Upgrade libxkbcommon to xkbcommon-1.0.0

1. Run meson build locally:
meson config -Denable-x11=false -Denable-wayland=false -Denable-docs=false

2. Copy over generated parser.h / parser.c

3. Copy over config.h, and remove defines for not supported functions.

+libxkbcommon 1.0.0 - 2020-09-05
+==================
+
+Note: this release is API and ABI compatible with previous releases -- the
+major version bump is only an indication of stability.
+
+- Add libxkbregistry as configure-time optional library. libxkbregistry is a C
+  library that lists available XKB models, layouts and variants for a given
+  ruleset. This is a separate library (libxkbregistry.so, pkgconfig file
+  xkbregistry.pc) and aimed at tools that provide a listing of available
+  keyboard layouts to the user. See the Documentation for details on the API.
+
+  Contributed by Peter Hutterer <@who-t.net>.
+
+- Better support custom user configuration:
+
+    * Allow including XKB files from other paths.
+
+      Previously, a 'symbols/us' file in path A would shadow the same file in
+      path B. This is suboptimal, we rarely need to hide the system files - we
+      care mostly about *extending* them. By continuing to check other lookup
+      paths, we make it possible for a XDG_CONFIG_HOME/xkb/symbols/us file to
+      have sections including those from /usr/share/X11/xkb/symbols/us.
+
+      Note that this is not possible for rules files, which need to be manually
+      controlled to get the right bits resolved.
+
+    * Add /etc/xkb as extra lookup path for system data files.
+
+      This completes the usual triplet of configuration locations available for
+      most processes:
+      - vendor-provided data files in /usr/share/X11/xkb
+      - system-specific data files in /etc/xkb
+      - user-specific data files in $XDG_CONFIG_HOME/xkb
+
+      The default lookup order user, system, vendor, just like everything else
+      that uses these conventions.
+
+      For include directives in rules files, the '%E' resolves to that path.
+
+    * Add a new section to the documentation for custom user configuration.
+
+  Contributed by Peter Hutterer <@who-t.net>.
+
+- Add an `xkbcli` command-line utility.
+
+  This tool offers various subcommands for introspection and debugging.
+  Currently the available subcommands are:
+
+  list
+    List available rules, models, layouts, variants and options
+
+  interactive-wayland
+    Interactive debugger for XKB keymaps for Wayland
+
+  interactive-x11
+    Interactive debugger for XKB keymaps for X11
+
+  interactive-evdev
+    Interactive debugger for XKB keymaps for evdev (Linux)
+
+  compile-keymap
+    Compile an XKB keymap
+
+  how-to-type
+    See separate entry below.
+
+  See the manpages for usage information.
+
+  Contributed by Peter Hutterer <@who-t.net>.
+
+- Add `xkb_utf32_to_keysym()` to translate a Unicode codepoint to a keysym.
+  When a special keysym (`XKB_KEY_` constant) for the codepoint exists, it is
+  returned, otherwise the direct encoding is used, if permissible.
+
+  Contributed by Jaroslaw Kubik <@froglogic.com>.
+
+- Add `xkb_keymap_key_get_mods_for_level()` which retrieves sets of modifiers
+  which produce a given shift level in a given key+layout.
+
+  Contributed by Jaroslaw Kubik <@froglogic.com>.
+
+- Add `xkbcli how-to-type` command, which, using `xkb_utf32_to_keysym()`
+  and `xkb_keymap_key_get_mods_for_level()` and other APIs, prints out all
+  the ways to produce a given keysym.
+
+  For example, how to type `?` (codepoint 63) in a us,de keymap?
+
+    $ xkbcli how-to-type --layout us,de 63 | column -ts $'\t'
+    keysym: question (0x3f)
+    KEYCODE  KEY NAME  LAYOUT#  LAYOUT NAME   LEVEL#  MODIFIERS
+    20       AE11      2        German        2       [ Shift ]
+    20       AE11      2        German        2       [ Shift Lock ]
+    61       AB10      1        English (US)  2       [ Shift ]
+
+- Add a new section to the documentation describing the format of the XKB
+  rules file.
+
+- Search for Compose in $XDG_CONFIG_HOME/XCompose (fallback to
+  ~/.config/XCompose) before trying $HOME/.XCompose.
+
+  Note that libX11 still only searches in $HOME/.XCompose.
+
+  Contributed by Emmanuel Gil Peyrot <@linkmauve.fr>.
+
+- Bump meson requirement to >= 0.49.0.
+
+- Fix build with byacc.
+
+- Fix building X11 tests on PE targets.
+
+  Contributed by Jon Turney <@dronecode.org.uk>
+
+- The tests no longer rely on bash, only Python (which is already used by
+  meson).
+
+- New API:
+  xkb_utf32_to_keysym
+  xkb_keymap_key_get_mods_for_level
+  XKB_KEY_XF86FullScreen
+
+
+libxkbcommon 0.10.0 - 2020-01-18
+===================
+
+- (security) Fix quadratic complexity in the XKB file parser. See commit
+  message 7c42945e04a2107827a057245298dedc0475cc88 for details.
+
+- Add $XDG_CONFIG_HOME/xkb to the default search path. If $XDG_CONFIG_HOME
+  is not set, $HOME/.config/xkb is used. If $HOME is not set, the path is not
+  added.
+
+  The XDG path is looked up before the existing default search path $HOME/.xkb.
+
+  Contributed by Peter Hutterer <@who-t.net>.
+
+- Add support for include statements in XKB rules files.
+
+  This is a step towards making local XKB customizations more tenable and
+  convenient, without modifying system files.
+
+  You can now include other rules files like this:
+
+      ! include %S/evdev
+
+  Two directives are supported, %H to $HOME and %S for the system-installed
+  rules directory (usually /usr/share/X11/xkb/rules).
+
+  See commit message ca033a29d2ca910fd17b1ae287cb420205bdddc8 and
+  doc/rules-format.txt in the xkbcommon source code for more information.
+
+  Contributed by Peter Hutterer <@who-t.net>.
+
+- Downgrade "Symbol added to modifier map for multiple modifiers" log to a
+  warning.
+
+  This error message was too annoying to be shown by default. When working on
+  keymaps, set `XKB_LOG_LEVEL=debug XKB_LOG_VERBOSITY=10` to see all possible
+  messages.
+
+- Support building on Windows using the meson MSVC backend.
+
+  Contributed by Adrian Perez de Castro <@igalia.com>.
+
+- Fix bug where the merge mode only applied to the first vmod in a
+  `virtual_modifiers` statement. Given
+
+      augment virtual_modifiers NumLock,Alt,LevelThree
+
+  Previously it was incorrectly treated as
+
+      augment virtual_modifiers NumLock;
+      virtual_modifiers Alt;
+      virtual_modifiers LevelThree;
+
+  Now it is treated as
+
+      augment virtual_modifiers NumLock;
+      augment virtual_modifiers Alt;
+      augment virtual_modifiers LevelThree;
+
+- Reject interpret modifier predicate with more than one value. Given
+
+      interpret ISO_Level3_Shift+AnyOf(all,extraneous) { ... };
+
+  Previously, extraneous (and further) was ignored. Now it's rejected.
+
+- Correctly handle capitalization of the ssharp keysym.
+
+- Speed up and improve the internal `xkeyboard-config` tool. This tool
+  compiles all layout/variant combinations in the xkeyboard-config dataset
+  and reports any issues it finds.
+
+  Contributed by Peter Hutterer <@who-t.net>.
+
+- Speed up "atoms" (string interning). This code goes back at least to X11R1
+  (released 1987).
+
+
+libxkbcommon 0.9.1 - 2019-10-19
+==================
+
+- Fix context creation failing when run in privileged processes as defined by
+  `secure_getenv(3)`, e.g. GDM.
+
+
+libxkbcommon 0.9.0 - 2019-10-19
+==================
+
+- Move ~/.xkb to before XKB_CONFIG_ROOT (the system XKB path, usually
+  /usr/share/X11/xkb) in the default include path. This enables the user
+  to have full control of the keymap definitions, instead of only augmenting
+  them.
+
+- Remove the Autotools build system. Use the meson build system instead.
+
+- Fix invalid names used for levels above 8 when dumping keymaps. Previously,
+  e.g. "Level20" was dumped, but only up to "Level8" is accepted by the
+  parser. Now "20" is dumped.
+
+- Change level references to always be dumped as e.g. "5" instead of "Level5".
+
+  Change group references to always be dumped capitalized e.g. "Group3" instead
+  of "group3". Previously it was inconsistent.
+
+  These changes affect the output of xkb_keymap_get_as_string().
+
+- Fix several build issues on macOS/Darwin, Solaris, NetBSD, cross compilation.
+
+- Port the interactive-wayland test program to the stable version of xdg-shell.
+
+
+libxkbcommon 0.8.4 - 2019-02-22
+==================
+
+- Fix build of xkbcommon-x11 static library with meson.
+
+- Fix building using meson from the tarball generated by autotools.
+
+
+libxkbcommon 0.8.3 - 2019-02-08
+==================
+
+- Fix build of static libraries with meson.
+  (Future note: xkbcommon-x11 was *not* fixed in this release.)
+
+- New API:
+  XKB_KEY_XF86MonBrightnessCycle
+  XKB_KEY_XF86RotationLockToggle
+
+
+libxkbcommon 0.8.2 - 2018-08-05
+==================
+
+- Fix various problems found with fuzzing (see commit messages for
+  more details):
+
+    - Fix a few NULL-dereferences, out-of-bounds access and undefined behavior
+      in the XKB text format parser.
+
+
+libxkbcommon 0.8.1 - 2018-08-03
+==================
+
+- Fix various problems found in the meson build (see commit messages for more
+  details):
+
+    - Fix compilation on Darwin.
+
+    - Fix compilation of the x11 tests and demos when XCB is installed in a
+      non-standard location.
+
+    - Fix xkbcommon-x11.pc missing the Requires specification.
+
+- Fix various problems found with fuzzing and Coverity (see commit messages for
+  more details):
+
+    - Fix stack overflow in the XKB text format parser when evaluating boolean
+      negation.
+
+    - Fix NULL-dereferences in the XKB text format parser when some unsupported
+      tokens appear (the tokens are still parsed for backward compatibility).
+
+    - Fix NULL-dereference in the XKB text format parser when parsing an
+      xkb_geometry section.
+
+    - Fix an infinite loop in the Compose text format parser on some inputs.
+
+    - Fix an invalid free() when using multiple keysyms.
+
+- Replace the Unicode characters for the leftanglebracket and rightanglebracket
+  keysyms from the deprecated LEFT/RIGHT-POINTING ANGLE BRACKET to
+  MATHEMATICAL LEFT/RIGHT ANGLE BRACKET.
+
+- Reject out-of-range Unicode codepoints in xkb_keysym_to_utf8 and
+  xkb_keysym_to_utf32.
+
+
+libxkbcommon 0.8.0 - 2017-12-15
+==================
+
+- Added xkb_keysym_to_{upper,lower} to perform case-conversion directly on
+  keysyms. This is useful in some odd cases, but working with the Unicode
+  representations should be preferred when possible.
+
+- Added Unicode conversion rules for the signifblank and permille keysyms.
+
+- Fixed a bug in the parsing of XKB key type definitions where the number
+  of levels were determined by the number of level *names*. Keymaps which
+  omit level names were hence miscompiled.
+
+  This regressed in version 0.4.3. Keymaps from xkeyboard-config were not
+  affected since they don't omit level names.
+
+- New API:
+  xkb_keysym_to_upper()
+  xkb_keysym_to_lower()
+
+
+libxkbcommon 0.7.2 - 2017-08-04
+==================
+
+- Added a Meson build system as an alternative to existing autotools build
+  system.
+
+  The intent is to remove the autotools build in one of the next releases.
+  Please try to convert to it and report any problems.
+
+  See http://mesonbuild.com/Quick-guide.html for basic usage, the
+  meson_options.txt for the project-specific configuration options,
+  and the PACKAGING file for more details.
+
+  There are some noteworthy differences compared to the autotools build:
+
+  - Feature auto-detection is not performed. By default, all features are
+    enabled (currently: docs, x11, wayland). The build fails if any of
+    the required dependencies are not available. To disable a feature,
+    pass -Denable-<feature>=false to meson.
+
+  - The libraries are either installed as shared or static, as specified
+    by the -Ddefault_library=shared/static option. With autotools, both
+    versions are installed by default.
+
+  - xorg-util-macros is not used.
+
+  - A parser generator (bison/byacc) is always required - there is no
+    fallback to pre-generated output bundled in the tarball, as there is
+    in autotools.
+
+- Removed Android.mk support.
+
+- Removed the *-uninstalled.pc pkgconfig files.
+
+- Ported the interactive-wayland demo program to v6 of the xdg-shell
+  protocol.
+
+- Added new keysym definitions from xproto.
+
+- New API:
+  XKB_KEY_XF86Keyboard
+  XKB_KEY_XF86WWAN
+  XKB_KEY_XF86RFKill
+  XKB_KEY_XF86AudioPreset
+
+
+libxkbcommon 0.7.1 - 2017-01-18
+==================
+
+- Fixed various reported problems when the current locale is tr_TR.UTF-8.
+
+  The function xkb_keysym_from_name() used to perform case-insensitive
+  string comparisons in a locale-dependent way, but required it to to
+  work as in the C/ASCII locale (the so called "Turkish i problem").
+
+  The function is now no longer affected by the current locale.
+
+- Fixed compilation in NetBSD.
+
+
+libxkbcommon 0.7.0 - 2016-11-11
+==================
+
+- Added support for different "modes" of calculating consumed modifiers.
+  The existing mode, based on the XKB standard, has proven to be
+  unintuitive in various shortcut implementations.
+
+  A new mode, based on the calculation used by the GTK toolkit, is added.
+  This mode is less eager to declare a modifier as consumed.
+
+- Added a new interactive demo program using the Wayland protocol.
+  See the PACKAGING file for the new (optional) test dependencies.
+
+- Fixed a compilation error on GNU Hurd.
+
+- New API:
+  enum xkb_consumed_mode
+  XKB_CONSUMED_MODE_XKB
+  XKB_CONSUMED_MODE_GTK
+  xkb_state_key_get_consumed_mods2
+  xkb_state_mod_index_is_consumed2
+
+
+libxkbcommon 0.6.1 - 2016-04-08
+==================
+
+- Added LICENSE to distributed files in tarball releases.
+
+- Minor typo fix in xkb_keymap_get_as_string() documentation.
+
+
+libxkbcommon 0.6.0 - 2016-03-16
+==================
+
+- If the XKB_CONFIG_ROOT environment variable is set, it is used as the XKB
+  configuration root instead of the path determined at build time.
+
+- Tests and benchmarks now build correctly on OSX.
+
+- An XKB keymap provides a name for each key it defines.  Traditionally,
+  these names are limited to at most 4 characters, and are thus somewhat
+  obscure, but might still be useful (xkbcommon lifts the 4 character limit).
+
+  The new functions xkb_keymap_key_get_name() and xkb_keymap_key_by_name()
+  can be used to get the name of a key or find a key by name.  Note that
+  a key may have aliases.
+
+- Documentation improvements.
+
+- New API:
+  xkb_keymap_key_by_name()
+  xkb_keymap_key_get_name()
+
+
+libxkbcommon 0.5.0 - 2014-10-18
+==================
+
+- Added support for Compose/dead keys in a new module (included in
+  libxkbcommon). See the documentation or the
+  xkbcommon/xkbcommon-compose.h header file for more details.
+
+- Improved and reordered some sections of the documentation.
+
+- The doxygen HTML pages were made nicer to read.
+
+- Most tests now run also on non-linux platforms.
+
+- A warning is emitted by default about RMLVO values which are not used
+  during keymap compilation, which are most often a user misconfiguration.
+  For example, "terminate:ctrl_alt_backspace" instead of
+  "terminate:ctrl_alt_bksp".
+
+- Added symbol versioning for libxkbcommon and libxkbcommon-x11.
+  Note: binaries compiled against this and future versions will not be
+  able to link against the previous versions of the library.
+
+- Removed several compatablity symbols from the binary (the API isn't
+  affected). This affects binaries which
+
+  1. Were compiled against a pre-stable (<0.2.0) version of libxkbcommon, and
+  2. Are linked against the this or later version of libxkbcommon.
+
+  Such a scenario is likely to fail already.
+
+- If Xvfb is not available, the x11comp test is now correctly skipped
+  instead of hanging.
+
+- Benchmarks were moved to a separate bench/ directory.
+
+- Build fixes from OpenBSD.
+
+- Fixed a bug where key type entries such as "map[None] = Level2;" were
+  ignored.
+
+- New API:
+  XKB_COMPOSE_*
+  xkb_compose_*
+
+
+libxkbcommon 0.4.3 - 2014-08-19
+==================
+
+- Fixed a bug which caused xkb_x11_keymap_new_from_device() to misrepresent
+  modifiers for some keymaps.
+
+  https://github.com/xkbcommon/libxkbcommon/issues/9
+
+- Fixed a bug which caused xkb_x11_keymap_new_from_device() to ignore XKB
+  PrivateAction's.
+
+- Modifiers are now always fully resolved after xkb_state_update_mask().
+  Previously the given state components were used as-is, without
+  considering virtual modifier mappings.
+  Note: this only affects non-standard uses of xkb_state_update_mask().
+
+- Added a test for xkbcommon-x11, "x11comp". The test uses the system's
+  Xvfb server and xkbcomp. If they do not exist or fail, the test is
+  skipped.
+
+- Fixed memory leaks after parse errors in the XKB yacc parser.
+  The fix required changes which are currently incompatible with byacc.
+
+
+libxkbcommon 0.4.2 - 2014-05-15
+==================
+
+- Fixed a bug where explicitly passing "--enable-x11" to ./configure would
+  in fact disable it (regressed in 0.4.1).
+
+- Added @since version annotations to the API documentation for everything
+  introduced after the initial stable release (0.2.0).
+
+- Added a section to the documentation about keysym transformations, and
+  clarified which functions perform a given transformation.
+
+- XKB files which fail to compile during keymap construction can no longer
+  have any effect on the resulting keymap: changes are only applied when
+  the entire compilation succeeds.
+  Note: this was a minor correctness issue inherited from xkbcomp.
+
+- Fix an out-of-bounds array access in src/x11/util.c:adopt_atoms()
+  error-handling code.
+  Note: it seems impossible to trigger in the current code since the input
+  size cannot exceed the required size.
+
+
+libxkbcommon 0.4.1 - 2014-03-27
+==================
+
+- Converted README to markdown and added a Quick Guide to the
+  documentation, which breezes through the most common parts of
+  xkbcommon.
+
+- Added two new functions, xkb_state_key_get_utf{8,32}(). They
+  combine the operations of xkb_state_key_get_syms() and
+  xkb_keysym_to_utf{8,32}(), and provide a nicer interface for it
+  (espcially for multiple-keysyms-per-level).
+
+- The xkb_state_key_get_utf{8,32}() functions now apply Control
+  transformation: when the Control modifier is active, the string
+  is converted to an appropriate control character.
+  This matches the behavior of libX11's XLookupString(3), and
+  required by the XKB specification:
+  https://www.x.org/releases/current/doc/kbproto/xkbproto.html#Interpreting_the_Control_Modifier
+
+  https://bugs.freedesktop.org/show_bug.cgi?id=75892
+
+- The consumed modifiers for a key are now calculated similarly
+  to libX11. The previous behavior caused a bug where Shift would
+  not cancel an active Caps Lock.
+
+- Make xkbcommon-x11 work with the keymap reported by the XQuartz
+  X server.
+
+  https://bugs.freedesktop.org/show_bug.cgi?id=75798
+
+- Reduce memory usage during keymap compilation some more.
+
+- New API:
+  xkb_state_key_get_consumed_mods()
+  xkb_state_key_get_utf8()
+  xkb_state_key_get_utf32()
+
+- Deprecated API:
+  XKB_MAP_COMPILE_PLACEHOLDER, XKB_MAP_NO_FLAGS
+    use XKB_KEYMAP_NO_FLAGS instead.
+
+- Bug fixes.
+
+
+libxkbcommon 0.4.0 - 2014-02-02
+==================
+
+- Add a new add-on library, xkbcommon-x11, to support creating keymaps
+  with the XKB X11 protocol, by querying the X server directly.
+  See the xkbcommon/xkbcommon-x11.h header file for more details.
+  This library requires libxcb-xkb >= 1.10, and is enabled by default.
+  It can be disabled with the --disable-x11 configure switch.
+  Distributions are encouraged to split the necessary files for this
+  library (libxkbcommon-x11.so, xkbcommon-x11.pc, xkbcommon/xkbcommon-x11.h)
+  to a separate package, such that the main package does not depend on
+  X11 libraries.
+
+- Fix the keysym <-> name lookup table to not require huge amounts of
+  relocations.
+
+- Fix a bug in the keysym <-> name lookup, whereby lookup might fail in
+  some rare cases.
+
+- Reduce memory usage during keymap compilation.
+
+- New API:
+  New keysyms from xproto 7.0.25 (German T3 layout keysyms).
+  XKB_MOD_NAME_NUM for the usual NumLock modifier.
+  xkb_x11_* types and functions, XKB_X11_* constants.
+
+
+libxkbcommon 0.3.2 - 2013-11-22
+==================
+
+- Log messages from the library now look like "xkbcommon: ERROR" by
+  default, instead of xkbcomp-like "Error:   ".
+
+- Apply capitalization transformation on keysyms in
+  xkb_keysym_get_one_sym(), to match the behavior specified in the XKB
+  specification:
+  https://www.x.org/releases/current/doc/kbproto/xkbproto.html#Interpreting_the_Lock_Modifier
+
+- Support byacc for generating the parser, in addition to Bison.
+
+- New API:
+  XKB_KEY_XF86AudioMicMute keysym from xproto 7.0.24.
+  XKB_KEYSYM_NO_FLAGS
+  XKB_CONTEXT_NO_FLAGS
+  XKB_MAP_COMPILE_NO_FLAGS
+
+- Bug fixes.
+
+
+libxkbcommon 0.3.1 - 2013-06-03
+==================
+
+- Replace the flex scanner with a hand-written one. flex is no longer
+  a build requirement.
+
+- New API:
+  xkb_keymap_min_keycode()
+  xkb_keymap_max_keycode()
+  xkb_keymap_key_for_each()
+
+
+libxkbcommon 0.3.0 - 2013-04-01
+==================
+
+- Allow passing NULL to *_unref() functions; do nothing instead of
+  crashing.
+
+- The functions xkb_keymap_num_levels_for_key() and
+  xkb_keymap_get_syms_by_level() now allow out-of-range values for the
+  'layout' parameter. The functions now wrap the value around the number
+  of layouts instead of failing.
+
+- The function xkb_keysym_get_name() now types unicode keysyms in
+  uppercase and 0-padding, to match the format used by XKeysymToString().
+
+- Building Linux-specific tests is no longer attempted on non-Linux
+  environments.
+
+- The function xkb_keymap_new_from_names() now accepts a NULL value for
+  the 'names' parameter, instead of failing. This is equivalent to passing
+  a 'struct xkb_rule_names' with all fields set to NULL.
+
+- New API:
+  xkb_keymap_new_from_buffer()
+
+- Bug fixes.
