Adds the SANITIZE_TARGET=integer_overflow build option to apply signed and
unsigned integer overflow sanitization globally. This implements the
Soong side of the build option.
An additional build option is provided to control whether or not to run
in diagnostics mode, controlled by SANITIZE_TARGET_DIAG. This works the
same way that SANITIZE_TARGET does and currently only supports
'integer_overflow' as an option.
A default sanitizer blacklist is added to avoid applying sanitization
to functions that are likely to exhibit benign overflows.
Bug: 30969751
Test: Building with and without the new flags, device boot-up, tested
various permutations of controlling the new flags from build files.

If a vendor (or vendor_available) lib has a dependency to a llndk
library, the name of the llndk library is modified to <name>.llndk.
There was a bug that this name modification is done only for shared_libs
property, but not for export_shared_lib_headers property. As a result,
the headers of the llndk was not re-exported. Fix the bug by modifying
export_shared_lib_headers property as well.

Test: look into out/soong/Android-<target>.mk. libutils.vendor has

Adding a mechanism to conditionally exclude some shared library
dependencies when a lib is built for vendors.
Without this, some libraries cannot be earily marked as vendor_available
if they are depending on shared libs can shouldn't be marked as
vendor_available.
By using exclude_shared_libs with exclude_srcs (or __ANDROID_VNDK__
macro), we can eliminate the unnecessary dependency for vendors.

Setting Sanitize.Diag.Undefined to true does not enable diagnostics for
all possible UBSan sanitizers that might be declared in Sanitize.Misc_undefined
(specifically unsigned-integer-overflow and nullability-*). This adds an
equivalent Sanitize.Diag.Misc_undefined string array to allow diagnostics to
be enabled in these sanitizers.
Bug: 62546512
Test: make works and device boots.
Test: Tested an Android.bp generated binary with the new field enabling
unsigned-integer-overflow diagnostics.

Also filter out -Wl,--no-undefined for all host sanitizers, not just ASan.
UBSan on host defaults to no-trap (i.e. diagnostic mode), and that requires
the runtime library and runs into the same problem with undefined symbols as ASan.

(cherry picked from commit fe9bc1dccb)
We now add export_static_lib_headers, export_generated_headers to the
filters while dumping the abi of a library using header-abi-dumper
(through -I<dir> additions to the invocation of header-abi-dumper and
header-abi-linker)
Also add support for zipped reference source based abi dumps.
Test: mm -j64 in hardware/interfaces/nfc/default/1.0 produces
android.hardware.nfc@1.0.so.lsdump with abi filtered out using generated
headers.
Test: Copied the linked abi dumps produced by mm -j64 in bionic/libc to
prebuilts/abi-dumps/ndk and gzipped them. Ran mm -j64 again in
bionic/libc and verified header-abi-diff getting invoked.

This is not very helpful - most of the characters are used to show the
output path, which contains useful information like target architecture,
but also contains most of the path to the source files twice, and less
useful information like the exact variant name used by soong.
