Currently, ChromeOS defines the OS_LINUX directive as well as
OS_CHROMEOS. We're working to separate these two, so we're
making the fact that OS_LINUX == OS_LINUX || OS_CHROMEOS
explicit.

The former non-overloaded variants are deprecated.
Removed casts where they are now unnecessary.
This is a mechanical change; there is no intended behavior change.

This CL moves Zucchini-gen invocation code from zucchini_commands.cc
(in target zucchini) to zucchini_integration.cc (in target zucchini_io)
to clean up layering in Zucchini API, i.e.:
- zucchini_lib: Operates on buffers only.
- zucchini_io: Adds files interface, uses memory-mapped I/O.
- zucchini: Stand-alone executable that parses command-line arguments.
Other changes:
- Rename zucchini_lib functions (zuchcini.h), to dedup names and
emphasize that these functions operate on buffers:
- GenerateEnsemble() -> GenerateBuffer(),
- GenerateEnsembleWithImposedMatches() -> GenerateBufferImposed(),
- GenerateRaw() -> GenerateBufferRaw(),
- Apply() -> ApplyBuffer().
These renames only affect Zucchini and various tests.
- Variable renames and parameter reordering in zucchini_integration.cc.
- Remove '-dd' param in help text of Zucchini-detect (was never ported
from Trunk, and has been recently deleted there as well).
- Replace all base::File&& with base::File.
- Miscellaneous cleanup for header include.
- Update README.md.

Previously Zucchini-gen uses built-in heuristics to perform element
matching for ensemble patch generation. This CL adds an option
(accessible via the -impose parameter) to specify elements in "old"
and "new", and how they match. This allows the default heuristics to be
overridden, and enables external applications (who perhaps have better
ideas of element matching, e.g., have access to archiving programs) to
better use Zucchini to patch archives.
Zucchini-match is updated to prints the -impose command line to repeat
its results. Also, ElementMatch::ToString() is added.

By defaulti, Zucchini deletes the output (patch or patched "new") file
upon failure. The "-keep" debug flag overrides this behavior, so the
bad output file can be examined. This CL adds the flag for Zucchini-gen
and Zucchini-apply.
This CL also removes a duplicated call to Ensemble::CheckOldFile(),
which checks the CRC32 of the "old" file. This removal prevents
redundant work and slightly speed up Zucchini-apply (by ~5%).

Reintroduces the PeakPageMemory (Peak Virtual Memory) and
PeakWorkingSetSize (Virtual Memory High Water Mark) metrics to Linux
builds of Zucchini. Linux is used for benchmarking of ELF and DEX
variants of Zucchini as well as general intergration and regression
testing so it is nice to have these metrics remain in the program.
The method used is based on code in base/process/internal_linux.[h|cc]
however, it avoids the overhead of having to create key value pairs
for all of the metrics so is slightly faster. Moreover, the contents
of internal_linux are intended to be private to base/process so in
order to get these metrics it is necessary to replicate part of the
code.
These were originally removed in:
https://chromium-review.googlesource.com/c/chromium/src/+/951923.
Also fixes some weirdness with "// defined(...)" comments.

depend on Disassembler.
The number of CreateEquivalenceMap() iterations used be constant
kNumIteraitons = 2. This CL makes the value depend on architecture.
Current assignment:
- DisassemblerNoOp: 1, since no pointers are identified (though in this
case, CreateEquivalenceMap() should not be called).
- DisassemblerWin32: 2.
Upcoming DisassemblerDex will use 4.
Also applying generic cleanups on headers and comments.

(Use "git log --follow" to see older revisions of files).
/components/ is the most logical place to put Zucchini, which only
depends on /base and /testing/gtest. This move also enables Zucchini to
be used by the Component Updater. Details:
- Move all files; run the following to change deps and guards:
sed 's/chrome\/installer/components/' *.cc *.h -i
sed 's/CHROME_INSTALLER/COMPONENTS/' *.cc *.h -i
- Sorting works out pretty well!
- Change all 'chrome/installer/zucchini' to 'components/zucchini'
throughout other parts of the repo; sort if necessary.
- Fix 6 'git cl lint' errors.
- Change 1 Bind() usage to BindRepeated().
- Update OWNER.
