Reuses the cc.Stripper logic. Abstracts Stripper to avoid the spreading
of references to the cc package.
rustc requires unstripped libraries (precisely, with the `.rustc`
section) when building dependent targets. Contrary to cc, the output of
a compiler module will remain unstripped and only an extra build rule
will be added. This rule will be referenced at install time (in
baseCompiler.install or androidmk).
This change drastically reduces the size of the installed libraries:

Device binaries currently are linked statically by default. Instead we
should be linking these dynamic by default. To avoid conflicts when

We don't need the prebuilt versions. The NDK CRT objects are (now)
built from the platform sources and the only difference is that the
NDK CRT objects also include an ELF note that identifies the NDK
version, which isn't helpful for anything built by the platform.
Add a `crt` property to cc_object that allows CRT objects to identify
themselves. CRT objects, unlike other modules, will have a variant
built per-API level they support, rather than just an SDK variant and
a platform variant. This is needed because new CRT objects will rely
on APIs not available in old libcs and old CRT objects will not
support all the features of a modern one.

This allows SourceProvider modules to create rust_library variants so
that generated source can be referenced as an external crate rather than
via an include macro. This is done by including rust_bindgen modules
like any other library, as a dependency in either rlibs, dylibs, or
rustlibs.
This renames the stem and flags properties for rust_bindgen modules to
source_stem and bindgen_flags, respectively. This deconflicts with the
usage in baseCompiler.
This also removes 'subName' from the Module struct and moves it over to
SourceProvider, which was the only user. This allows us to set it in
baseSourceProvider's AndroidMk; setting it in Module's AndroidMk was
causing problems finding NOTICE files for bindgen library variants.

rust_library modules no longer produce "link" variants alongside
"rust_libraries" variants as the former have been moved to rust_ffi
modules. rust_library modules however still create empty link variants
and code paths still assume that modules can support both rust linkage
and cc linkage. This adds unnecessary complexity that no longer serves a
purpose.
This cleans this up by removing the unused "link" variant for
rust_library modules and simplifies code paths that can now assume
modules are either a rust library or a cc library, but not both.
This also fixes a bug where Shared() was returning the wrong value.

dependencyTag uses a set of predefined tags to identify different types
of dependencies. There are already multiple bits of metadata stored
in the dependency tag (Library, Shared, ReexportFlags), and supporting
them all requires a combinatorial explosion of predefined tags and
causes issues when using equality comparisons if a new bit of metadata
is added.
Add a new libraryDependencyTag type that will contain the metadata
bits, and replace the quality comparisons with checks on the metadata
bits.
There are 5 TODOs where modifying the checks identified problems with
the existing checks. These were left in place to produce identical
build output and will be fixed separately.

rust_bindgen was not hermetic previously as it would pull in host
headers for device targets. This fixes that by using the same flags we
use when compiling with Clang. This also makes sure our rust_bindgen
headers are built as similar as possible to their respective

This also pulls in the bionic dependencies as well, which provide the
headers required for device targets.

Modules defined in the srcs property are automatically added as
dependencies with AddDependency(), which will use any variant available.
This can cause incorrect architecture bindings to be silently pulled in,
such as when a host module uses a rust_bindgen module that doesn't
create a host variant.
This moves populating depPaths.SrcDeps over to depsToPaths and adds a
check for SourceProviders to make sure the correct OS and architecture
is being used.

Allow rust modules to depend on and use generated source code provided
by SourceProvider modules and genrule modules without resorting to
hardcoded output paths.
All generated sources are now copied to a dependent module's
intermediates directory, then OUT_DIR is set to point to that path when
calling rustc. This matches the common convention used in most rust
crates to include generated source code from the path defined in the
OUT_DIR environment variable.
A couple other small notable changes are included in this CL:
* prebuiltLibraries can no longer include generated source files as they
should be prebuilt.
* srcPathFromModuleSrcs now excludes the main source file from the
second return value so its a list of only the generated sources.

With proper prebuilt modules, we can avoid any rustc implicit sysroot
searching.
Asd a bonus, this should make rust-project.json generation correctly
grab otherwise implicit dependencies.
Prebuilt rlibs may include several dependency rlibs. Without a
link_dirs attribute, every dependency (even if unexported) would need a
separate module.
Previously we were casing out on exact structs, which might be OK when
libraryDecorator and procMacroDecorator were the only possibilities, but
repeating the logic for three types is too much. Using an interface
makes this logic scale better.

When a lib has sdk_version set, an SDK variant and a platform variant
are created by the sdkMutator. Then by the versionMutator, if the
library had 'stubs.versions' property, one or more versioned variants
and one impl variant are created for each of the two (SDK and platform)
variants. As a concrete example,
cc_library {
name: "foo",
sdk_version: "current",
stubs: { versions: ["1", "2"], },
}
would create 6 variants:
1) (sdk: "", version: "")
2) (sdk: "", version: "1")
3) (sdk: "", version: "2")
4) (sdk: "sdk", version: "")
5) (sdk: "sdk", version: "1")
6) (sdk: "sdk", version: "2")
This is somewhat uncessary because the need for the SDK mutator is to
have the platform variant (sdk:"") of a lib where sdk_version is unset,
which actually makes sens for the impl variant (version:""), but not
the versioned variants (version:"1" or version:"2").
This is not only unncessary, but also causes duplicate module
definitions in the Make side when doing an unbundled build. Specifically,
The #1 and #4 above both are emitted to Make and get the same name
"foo".
To fix the problem and not to create unnecessary variants, the versioned
variants are no longer created for the sdk variant. So, foo now has
the following variants only.
1) (sdk: "", version: "") // not emitted to Make (by versionMutator)
2) (sdk: "", version: "1") // not emitted to Make (by versionMutator)
3) (sdk: "", version: "2") // emitted to Make (by versionMutator)
4) (sdk: "sdk", version: "") // not emitted to Make (by versionMutator)

Compiling native modules against the NDK disables platform features
like ASAN. For anything shipped on the system image there is no
reason to compile against the NDK. Add a new mutator to Soong that
creates a platform and an SDK variant for modules that set
sdk_version, and ignore sdk_version for the platform variant. The
SDK variant will be used for embedding in APKs that may be installed
on older platforms. Apexes use their own variants that enforce
backwards compatibility.

The APEX dependency is more correctly tracked. Previously, the
dependency was tracked while we gather modules that will be installed to
an APEX. This actually was incorrect because we skipped many dependency
types that we don't need to follow to gather the modules list, such as
the headers dependency.
Now, the dependency is tracked directly when a module is mutated for an
APEX. In other words, if a module is mutated for an apex X, then the
module will appear in the X-deps-into.txt file.
This change also changes the format of the txt file. It now clearly
shows why a module is included in the APEX by showing the list of
modules that depend on the module.
