A cc_library or cc_library_shared can be configured to have stubs
variants of the lib.
cc_library_shared {
name: "libfoo",
srcs: ["foo.cpp"],
stubs: {
symbol_file: "foo.map.txt",
versions: ["1", "2", "3"],
},
}
then, stubs variants of libfoo for version 1, 2, and 3 are created
from foo.map.txt. Each version has the symbols from the map file where
each symbol is annotated with the version that the symbol was introduced
via the 'introduced=<ver>' syntax. The versions don't need to be in sync
with the platform versions (e.g., P for 28). The versions are local to
the library.
For another library or executable to use the versioned stubs lib, use
the new 'name#ver' syntax to specify the version:
cc_binary {
name: "test",
....
shared_libs: ["libFoo#2"],
}
Internally, a new mutator 'version' is applied to all cc.Module objects.
By default, a variant named 'impl' is created for the non-stub version.
If the versions property is set, additional variations are created per a
version with the mutable property BuildStubs set as true, which lets the
compiler and the linker to build a stubs lib from the symbol file
instead from the source files.
This feature will be used to enforce stable interfaces among APEXs. When
a lib foo in an APEX is depending on a lib bar in another APEX, then bar
should have stable interface (in C lang) and foo should be depending on
one of the stubs libs of bar. Only libraries in the same APEX as foo can
link against non-stub version of it.

From now on, a c++ shared library can be built only with adding
".sysprop" description file to srcs. Sysprop library generator will
automatically generate a .cpp and .h files, and the header file will be
exposed to any clients linking against the shared library. For the full
schema of description file, see system/tools/sysprop/sysprop.proto.
Bug: 80125326
Test: 1) write a .sysprop description file.
2) create cc_library_shared and add description file to srcs.
3) create another module, link against library of 2), include generated
header, and access generated sysprop functions
4) see compile succeeded.

This commit changes "current" to ctx.DeviceConfig.PlatformVndkVersion().
This change make it possible to place ABI dumps in
prebuilts/abi-dumps/vndk/${version} instead of
prebuilts/abi-dumps/vndk/current.
If BOARD_VNDK_VERSION is not specified or is equal to "current",
PLATFORM_VNDK_VERSION (either PLATFORM_SDK_VERSION or
PLATFORM_VERSION_CODENAME) will be chosen. Currently,
BOARD_VNDK_VERSION is always equal to "current" because both system and
vendor images are built in a single source tree.
In the future, if the system image and vendor images are separately
built in different source trees, BOARD_VNDK_VERSION will be set to other
values and we should respect that value.
Test: Create an ABI dump under
prebuilts/abi-dumps/vndk/${PLATFORM_VNDK_VERSION}, make some ABI
breakages, and see whether the checks are working.

Historically, we've always passed '-I .' as the first argument to
protoc, essentially treating all proto file package names as their full
path in the android source tree. This would make sense in a monorepo
world, but it makes less sense when we're pulling in external projects
with established package names.
So keep the same default (for now), but allow individual builds to opt
into using local paths as the default names with
'canonical_path_from_root: false'. A cleanup effort and/or large scale
change in the future could change the default to false.
As part of this, run protoc once per input proto file, since the flags
may need to change per-file. We'll also need this in order to specify
--dependency_out in the future.

This commit adds `extends: "name"` property and provides basic support
to VNDK extensions. This is the simplest example:
```
cc_library {
name: "libvndk",
vendor_available: true,
vndk {
enabled: true,
},
}
cc_library {
name: "libvndk_ext",
vendor: true,
vndk: {
enabled: true,
extends: "libvndk",
},
}
```
A vndk extension library must extend an existing vndk library which has
`vendor_available: true`. These two libraries must have the same
`support_system_process` property.
VNDK-ext libraries are installed to `/vendor/lib[64]/vndk` and
VNDK-SP-ext libraries are installed to `/vendor/lib[64]/vndk-sp` by
default.
If there is a matching abi-dumps in `prebuilts/abi-dumps`,
`header-abi-diff` will be invoked to check for ABI breakages.

Wrap blueprint.PackageContext so that the *Func methods can provide
an android.Config instead of an interface{}. The modified signatures
means that every method in ModuleContext and SingletonContext
that takes a blueprint.PackageContext now needs to be wrapped to
take an android.PackageContext.
SingletonContext wasn't previously wrapped at all, but as long
as it is, wrap everything like ModuleContext does. This requires
updating every Singleton to use the android-specific methods.

(a) Adds a second -version-script=... to the command line
when building components that use a version script. This ensures that
__cfi_check is also exported, and allows CFI to be enabled for these
components.
(b) Adds both topdown and bottom up mutators for CFI to help propagate

both generated variants
