Previous solution by using objcopy uses a quirky behaviour of the GNU
objcopy and there is no equivalent option in llvm-objcopy.
Instead of removing symbols, extract and repack libgcc to only include
required objects.

We rely on a weird, GNU specific behaviour of objcopy:
$ aarch64-linux-android-objcopy -w libgcc.a stripped.a --strip-unneeded-symbol=*
$ llvm-nm --defined-only stripped.a | grep multi
0000000000000000 T __multi3
$ aarch64-linux-android-objcopy -w libgcc.a stripped.a --strip-unneeded-symbol=* --keep-symbol=FOO
$ llvm-nm --defined-only stripped.a | grep multi
llvm-objcopy has a different, more consistent behaviour that does not
mark exported symbols as unneeded when "--keep-symbol" flag exists.
However this behaviour will leave most symbols not deleted in the
libgcc_stripped library.
Revert the change while I'm implementing an alternative solution.

sysprop_library now checks the API stability itself, cutting dependency
on java_sdk_library. Under the directory {module_dir}/api,
{module_name}-current.txt and {module_name}-latest.txt hold API
signatures.
When sysprop_library is built, or a user run "m {module_name}-check-api"
command, API check is performed. First, current.txt must have exactly
same signature with built sysprop_library module. Second, current.txt
must be compatible with latest.txt.
Build system emits a handy error message to generate/update those API
files, in case of missing or mismatching. Also, a script file for
freezing API files is introduced.
Bug: 131637873
Test: 1) m && boot blueline
Test: 2) m {sysprop_library} performs API check

This tool is used to modify apex_manifest.json when building apex
module.
Here's the usage:
usage: jsonmodify [-h] [-o output] [-v path value] [-s path value]
[-r path] [-a path [value ...]]
[input]
positional arguments:
input JSON file
optional arguments:
-h, --help show this help message and exit
-o output, --out output
write result to a file. If omitted, print to stdout
-v path value, --value path value
set value of the key specified by path. If path
doesn't exist, creates new one.
-s path value, --replace path value
replace value of the key specified by path. If path
doesn't exist, no op.
-r path, --remove path
remove the key specified by path. If path doesn't
exist, no op.
-a path [value ...], --append_list path [value ...]
append values to the list specified by path. If path
doesn't exist, creates new list for it.

If sort_bss_symbols_by_size is true, a shared library is built twice.
The first build generates an unsorted output file, which is used to
generate the symbol ordering file. The output of the second build is
a shared library with its bss symbols sorted by their size.
With this, the only user of symbol_ordering_file, libc, is migrated to
use the new property, so we remove symbol_ordering_file support as well.
Bug: 135754984
Test: Build and check the resulting libc.so has its bss symbols sorted.

clang-format tries to automatically detect the Cpp standard used,
particularly when determining to put spaces in template definitions:
Cpp03: std::vector<std::pair<bool, bool> >
vs
Cpp11: std::vector<std::pair<bool, bool>>
It doesn't always get this correct as seen in
https://android-review.googlesource.com/c/platform/system/core/+/973463/8
but since we know that all code within Android is C++17, we can safely
assume it should be formatted with the newer standard.
Test: clang-format doesn't break the above change.

As of [1], the Google format, which we default to, uses IncludeBlocks:
Regroup, which sorts all includes with <> and without .h into the top
group reserved for libc headers, e.g.:
+#include <android-base/properties.h>
+#include <android-base/strings.h>
#include <ctype.h>
#include <stdlib.h>
#include <sys/system_properties.h>
#include <iostream>
-#include <android-base/properties.h>
-#include <android-base/strings.h>
This is accurate to the Google C++ style guide, which states that
other library headers should be included with "", however we have a
strong tendency to use <> for these headers for Android, so we must
revert this change.
Note, clang-format allows regexes for creating the blocks as well,
however, short of including all possible libc headers, I don't think
there's a way to differentiate between <sys/wait.h> and
<other_lib/header.h>.

The jars containing the merged header classes from transitive
static dependencies were stripping all of META-INF/. Kotlin
puts metadata in META-INF that is used to map the package to
the static class that contains the package-level functions.
This also exposed that the metadata in META-INF is always
called "name.kotlin_module", so a library that contains
kotlin files with a dependency that also contains kotlin files
would shade the metadata file. Use a unique name instead.

When no-vendor-variant VNDK is enabled, the vendor variant of VNDK
libraries are not installed. Since not all VNDK libraries will be
ready for this, we keep a list of library names in cc/vndk.go to
indicate which libraries must have their vendor variants always
installed regardless of whether no-vendor-variant VNDK is enabled.
Also add --remove-build-id option to the strip script to facilitate
the check of functional identity of the two variants.
