This commit adds VTableLayoutDiffIR::IsExtended() that determines
whether the difference is a pure extension, i.e., appending virtual
functions to vtables.

The types defined in more than one source file are identified with
"#ODR:" and the source paths. The paths can be in intermediate
directories and differ between build targets. They cause ABI check
failure on opaque types. This commit fixes the bug by removing the
suffixes before the comparison.

Function parameters can be opaque and have no size information. For
example, __va_list in AArch64 ABI. header-abi-diff considers opaque
types compatible if their mangled names are the same.
The mangled name of __va_list can be _ZTI9__va_list or _ZTISt9__va_list.
They are also compatible.

This commit removes the comparison between class size and member offsets
from RecordTypeDiffIR::IsExtended. New members can be added to padding
space in a class without changing the existing members.

Resizing the parameters or return types changes the stack layout. It
is not an allowed extension to functions.
AbiDiffHelper::CompareFunctionTypes additionally checks the sizes of the
parameters and the return types. The difference cannot be ignored by
-allow-extensions. The user who intends to ignore the difference should
specify -ignore-symbols or -ignore-linker-set-key.

This commit adds RecordTypeDiffIR::IsExtended() that determines whether
the difference is a pure extension, i.e., appending members and
increasing the size. The extensions are stored in
record_type_extension_diffs in abi_diff messages. They can be ignored by
specifying -allow-extensions.

RecordTypeDiff and EnumTypeDiff in abi_diff.proto contain linker set
keys. The developers can copy them to the ignore list. The other Diff
messages do not need the field because it's in the messages imported
from abi_dump.proto.

Sometimes developers may want to ignore some incompatible changes in ABI
because it is safe for some reason. An option should be added to
header-abi-diff so it ignores these LinkerSetKeys passed from cli or
config file.
Test: perform abi diff on libz with abi-dump version 33 with the LinkerSetKey _ZTI14internal_stat is specified.

NDK and platform Libraries are required to ensure the compatibility
across SDK version. However, some changes of a library that break its
ABI compatibility are necessary. Thus a ignored_linker_set_keys option
is added to let developers to skip some symobls.

Skip loading config.json when the config.json is not found so the
header-abi-diff will still perform abi diff.

Change-Id: I92ebf7e7bfe6abb57bdefa211eaf604efaee517e
Enable the Cross-Version ABI diff configuration so developers can
specify different flags for current and previous version ABI Check. The
-target-version flag were added to determine the config section to be
selected. The details of this configuration logic could be found in
go/cross-version-abi-diff-configuration.
Test: preform abi diff with config.json
Bug: 239792343
Change-Id: I8fdad2d18096cfa7866183ecc2d7826682c85eb6
Since Cross-Version ABI Check is introduced, the flags could be
different when diffing with previous or current dumps. The structure and
format of the newly proposed config are changed so users can configure
flags for different diff targets. This CL changes the config format from
.ini to .json with the same features the format of the json is described
in go/cross-version-abi-diff-configuration.

header-checker build may use an older version of clang than the platform
version, causing errors for unknown cflags. Setting the env var allows
these errors to be suppressed.

* changes:
Refactor GetRefDumpDirStem to avoid excessive arguments passing
Generate dumps for non-VNDK into folder that matches Cross-Version ABI Check mechanism
Generate LLNDK ABI dumps to platform/ instead of vndk/
The arguments required by function get_ref_dump_dir_stem() would be
carried all the way to get_ref_dump_dir_stem(). In this CL, the logic
of get_ref_dump_dir_stem() would be wrapped into a class so that the
other functions can be cleaner.

The dumps of non-VNDK was generated to PLATFORM_SDK_VERSION. To enable
the Cross-Version ABI Check, before finalization (when
PLATFORM_VERSION_CODENAME is not REL), dumps should be generate to
current/ no matter what PLATFORM_SDK_VERSION is; After finalization,
dumps should be generate to PLATFORM_SDK_VERSION/.

Since vndk libraries don't need to maintain Cross-Version abi
compatibility. The newly proposed Cross-Version ABi checking mechanism
is applied to only ndk/ and platform/. The dumps of LLNDK libraries
should be generated to platform/ to be benefited from this checking
mechanism.
