Colin Cross 7228ecd5e3 Move cc.imageMutator into the android package
Prepare for making the image mutator available to all modules and
moving it between the os and arch mutators by moving it into the
android package and using an interface implemented by the module
types to control it.

Jiyong Park fc752ca1ac Let genrule be mutatable by the apex mutator
genrule modules were not mutated by the apex mutator. As a result, a
module that is mutated for an apex have depended on the genrule modules
host_bionic_linker_{asm|flags} that are not mutated for the APEX.

This in turn caused an inconsistency problem because the
host_bionic_linker_* genrules use the dynamic linker that isn't mutated
for APEX as an input, while the outputs of the genrules are used by
modules mutated for APEX. The inconsistency caused b/135008828.

Fixing this issue by correctly let genrule to be mutated by the apex
mutator.

Jiyong Park 7ed9de3b81 Add support for versioned stubs.
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.

Jiyong Park 3f736c9661 Add recovery_available to cc_genrule
recovery_available property is required in cc_genrule. Specifically,
we will mark libminijail as recovery_available:true as part of building
adbd and other stuffs for recovery. Some source code of libminijail is
created via cc_genrule, so we need recovery_available in the module
type.

Dan Willemsen 3e5bdf29ba Add cc_genrule
cc_genrule is the same as a normal genrule, but can depend on other cc
modules (like cc_object).
