45901edb9a Ensure hermetic device rust_bindgen.
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
cc_libraries.

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

Bug: 162007475
Test: device rust_bindgen deps file does not reference host headers.

07cbaf4d89 Enforce correct variant usage for rust_bindgen.
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.

Bug: 161826371
Test: Soong no longer silently pulls in bindings for the wrong
      target.
Test: New Soong test to catch this case passes.

43845688bc Allow rust module dependency on SourceProviders.
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.

Bug: 159064919
Test: Local example rust_library compiles with rust_bindgen dependency.
Test: Local example rust_library compiles with genrule dependency.
Test: Collision detected when multiple providers produce similar output.
Test: New Soong tests pass.

bb3add1104 rust: Suppress default sysroot unconditionally
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.

c761eeca48 rust: Mutate prebuilt modules dylib/rlib
This change makes it possible to use a single module to provide both
dylib and rlib varieties of a library. This allows the use of libstd and
libtest from a rustlibs property, allowing linkage type to change
for different variants.

2ae0513a8e rust: Change default variants
rust_library now produces only rlib and dylib variants.
rust_library_foreign now produces static and shared variants.

This change was made because both are common cases, but all four
together essentially never happens. This allows us to have fewer repeat
module definitions.

1f7f70fe39 Remove moduleContextImpl struct
The moduleContextImpl structure contains duplicate information on the
contexts. BaseModuleContext, ModuleContext and DepsContext can already
surface which Module is being processed via Module(). Because most of
the Rust-specific methods on the *Context structures simply forward to
the Module methods, expose a RustModule() method.

a0cd8f9acb Add gcov coverage support to Rust modules.
This adds gcov coverage support for Rust device library and binary
modules (including test modules). Support is provided to pass Rust
static library gcno files to CC modules and visa versa.

Additional changes:
 * Begin mutator added for Rust modules.
 * SuffixInList added to android package.
 * CoverageEnabled added to Coverage interface.
 * CoverageFiles added to LinkableLibrary interface.
 * Fix in coverage mutator for non-CC modules which marked the wrong
   variant as the coverage variant.
 * Added coverage libraries to the cc.GatherRequiredDepsForTest.

9d1df10e2a Provide 32-bit and 64-bit Rust libs by default.
CC libraries which depend on Rust libraries get missing dependency
errors when building 32-bit variants dependent on Rust modules which
don't explicitly have "multilib: both" declared.

Because CC libraries use MultilibBoth by default, Rust should do the
same.

This also fixes a bug where the ARM32 toolchain incorrectly embedded
toolchain64Bit instead of toolchain32Bit.

Bug: 154730212
Test: Rust libraries provide both variants by default.

22cef966e1 rust: Include Soong module name as metadata
If we want to build a component which uses two versions of a crate in
the dependency graph (for example, libc in std and libc from
external/crates), Rust requires at least one of them have a metadata
field to differentiate them.

Since Soong module names should be distinct for a given target, they
should serve as metadata.

ad8b18b872 Enforce correct rust library file names.
rustc expects libraries and proc_macro filenames to conform to
a particular format, alphanumeric with underscores and lib${crate_name}.*.
Enforce this with a check when getStem() is called.

This makes the crate_name property required for proc_macros and
libraries. This also removes the notion of a default crate name derived
from the module name. It's not needed for binaries, so this won't impact
them.

52767be335 Add support for Rust C libraries.
Adds the ability for rust modules to be compiled as C libraries, and
allows cc modules to depend on these rust-generated modules. This also
means that soong-rust should not have any dependencies on soong-cc aside
from what's required for testing.

There's a couple small fixes included as well:

 - A bug in libNameFromFilePath that caused issues when library's had
 "lib" in their name.
 - VariantName is removed from rust library MutatedProperties since this
 was unused.
