So we can do "#include <ext4_utils/make_ext4fs.h>" without adding
"LOCAL_C_INCLUDES += system/extras/ext4_utils".
Also clean up the #include lines in system/extras/ext4_utils/.
Test: `m checkbuild` works.

xattr_free_space() does not match kernel, it subtracts
sizeof(__u32) as a buffer zone to permit IS_LAST_ENTRY
to function. As documented in .../linux/fs/ext4/xattr.c:
+------------------+
| header |
| entry 1 | |
| entry 2 | | growing downwards
| entry 3 | v
| four null bytes | <<<< HERE is why sizeof(__u32)
| . . . |
| value 1 | ^
| value 3 | | growing upwards
| value 2 | |
+------------------+

Add the -B option to make_ext4fs, which causes it to record the block
ranges used for each (regular) file in the image. We can use this
information to construct more efficient block-based incremental OTAs.

Remove warnings called by duplicate definition of ALIGN macro.
Note that bionic/libc/include/sys/param.h defines ALIGN as
#define ALIGN(p) (((uintptr_t)(p) + ALIGNBYTES) &~ ALIGNBYTES)
which is not good - clashes with every other definition of ALIGN.

Move the kernel header includes into a single include file that
can deal with getting the kernel int types correct on all
platforms.

After commit 4df62f342dbbe2f5cca831ce789dc0426d32ec03,
occurs segmentation fault if mkuserimg.sh runs without FILE_CONTEXTS options.
It's due to strlen() for null value. To fix it, return 0 for null.

Add support for specifying filesystem capabilities when
creating a new filesystem.
The combination of SELinux extended attributes plus
filesystem capability extended attributes is too big
to fit inside one inode entry. Because of this, I added
support to ext4_utils to create an xattr block and link
the inode to that block. We continue to try to fit
everything inside the inode if possible, but fall over to
creating a block if the extended attribute is too big.

When the total dentry size is N * 4096 - 4 or N * 4096 - 8, there is
not enough room in the block to insert an extra padding dentry.
Instead, switch to always padding the previous dentry out to the end
of the block, which matches what the kernel does when creating new
directory entries.
Also fix dentry_size to return the size of all the dentries
without the padding, the len + 8 padding is incorrect, and the
DIV_ROUND_UP will round up to the correct number of blocks.

Extend make_ext4fs with support for looking up the right security context from
the file_contexts configuration and setting it in the generated image. This is
similar to the existing support for looking up the UID/GID/mode via
android_filesystem_config.h and setting it, but via configuration rather than
defined in a header.

This is not a full port of ext4_utils for windows.
Instead it merely enables use to use the library
for the 'create an empty fs image' functionality
as used by 'fastboot format'.

When computing the size of a directory that is being created,
make sure to include the size of the null entry at the end of
the list of entries in that directory.

The PAD_TO function was incorrectly handling values that were already
aligned, which could lead to overruns of the dentry block. Fix the
function, rename it to ALIGN, move it to ext4_utils.h, and use it
everywhere the dentry size is calculated.

Zero length files should just skip the block allocation so the
inode extent fields are empty.
