NDK has two ABI checks:
1. Check that prebuilt ABI exactly matches compiled binaries.
2. Check that ABI of level X compatible with level X+1.
The second check used compiled binaries for level X and prebuilts for
level X+1. But this approach may confuse people, because ABI change will
be shown "reversed". For example, adding new field to ABI monitored
binary of level X would be shown as "removed" when compared to level X+1
prebuilt.
This change uses prebuilts for both level X and level X+1. Given, that
prebuilts are checked to match compiled binaries, this should be enough.

Collect all NDK exported headers paths into a file that is used to
detect public types that should be ABI monitored.
Assume that we have the following code in exported header:
typedef struct Context Context;
typedef struct Output {
...
} Output;
void DoSomething(Context* ctx, Output* output);
If none of public headers exported to end-users contain definition of
"struct Context", then "struct Context" layout and members shouldn't be
monitored. However we use DWARF information from a real library, which
may have access to the definition of "string Context" from
implementation headers, and it will leak to ABI.
STG tool doesn't access source and header files, only DWARF information
from compiled library. And the DWARF contains file name where a type is
defined. So we need a rule to build a list of paths to public headers,
so STG can distinguish private types from public and do not monitor
private types that are not accessible to library users.

Soong currently adds -isystem
prebuilts/ndk/current/sources/cxx-stl/system/include to modules that
have ndk_system STL. This does not translate well to Bazel because of
its stricter sandboxing constraints.
In preparation for building sdk variants with Bazel, create an
indirection where sdk variants that use this STL depend on a
`ndk_system` header library module.
This should be a no-op in Soong, but the resultant ninja files are not
identical. (e.g diff https://diff.googleplex.com/#key=OOLtc1GFmDDF). The
-isystem now appears _before_ the local cflags. However, this should be
fine because we have a check in `CheckBadCompilerFlags` that bans use of

Soong's proto.include_dirs becomes the -I path for aprotoc cpp code
generation. This does not translate well to Bazel because it runs this
action in a sandbox. Even if we construct an -I path, the .proto files
will not be there. This CL attempts to handle this kind of dependency
automatically via bp2build.
For this hypothetical example
```
foo.proto # contains `import bar.proto"
Android.bp # cc_library {srcs:"foo.proto", p.include_dirs:["subdir"]},
subdir/bar.proto
```
Implementation details for CcProtoGen of foo
- Glob the labels of .proto files for each includeDir, and create a
proto_library that encapsulates them.
- Since Bazel poses a contraint that proto_library target needs to be
in the same pacakge as the .proto file, the proto_library might be created
in a subdirectory with an import_prefix
- Add bar's proto_library as transitive deps of foo's cc_proto_library.
This will be added to -I during aprotoc. We cannot add them to `deps`,
otherwise bar's symbols will be statically linked into foo's .a
file.
Implementation details for clang compile of foo
At the end of CcProtoGen, we have converted foo.proto
to .cpp/.h files. To compile them to .a files, we need the .h files
generated from bar.proto. Soong specifies this at the
top-level cc_library soong module, so add those deps as the
implementation deps for clang compile.
(Will add support for java in a follow-up CL)

If `srcs` contains a gensrcs/genrule module, the current bp2build module

To support `b test //path/to:my_test` command line, the actual
executable in the cc_test macro now has the __tf_internal suffix in its
name, so that the top level test suite target can be named without any suffixes.
See other CLs in this topic for more info.

Embedding multiple includes from a genrule may be difficult to read,
instead we generate a header library that contains the headers and all
include dirs that Soong generates.

This is prep work to add additional special handling for genrule
generated headers as there will be similar partitioning for those
headers.

This is currently implicitly added by the cc_test macro. This can cause
duplicate issues if users write a BUILD file as
```
cc_test (
name = "mytest",
deps = ["libgtest"],
)
```
Making this dep explicit in BUILD files prevents this issue.
The property `gtest` will not be removed as part of this CL. cc_test
macro will use this property to add some gtest specific copts

The generated module lets us keep the aconfig code in its own pacakge
and not infect all of the cc package with aconfig. It's also closer
to what bazel is going to do

The 'sdk_version' flag should be allowed to specify a preview API level
codename. Convert the raw name into an integer using the common library
functions. This also switches out the comparison logic to use the
ApiLevel as defined by the 'android' library instead of doing
string-to-int conversion on the output.
Test: Verified that setting VIC as an sdk_version does not crash.

Adds dylib support for vendor and recovery images.
This changes the default linkage for vendor and recovery images to
dylib, which matches the platform default linkage. This also means that
by default, dylib-std variants are used for rlib dependencies.

Build C/C++ targets with ThinLTO with "--lto-O0" by default. This takes
advantage of better dead code elimination and CFG simplification due to
ThinLTO's global view of the program, but do not enable the costly LTO
optimizations. This also makes builds faster because we can avoid doing
codegen for the dead code.

This is a revert of aosp/2449906
mixed build currently supports platform and apex variants of allowlisted
cc libraries. However when building apex variants, we would pass an
apexKey only for allowlisted _dcla_ libraries. This meant that for libraries in
mixed build allowlist but not in dcla allowlist, Soong's apex variants
were being replaced with Bazel's platform variants.
