Matthew Maurer 46c46ccafd rust: Do not pass -C prefer-dynamic for cdylib
cdylib targets cannot currently dynamically link to Rust crates, so this
flag was not actually doing anything, and in conjunction with -C lto
which we *do* want on for this target, causes a hard error on
rustc-1.40.0.

Bug: 147438124
Test: Build a rust_library module, this implicitly tries to build cdylib

Matthew Maurer 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.

Test: Build a rust library with "rlibs: ["liblibc"]" in the blueprint

Chih-Hung Hsieh 9a4a7bab41 Install rust tests under nativetest(64)
* Now the installation directories match those for C/C++ tests:
  * The relative_install_path refers to path under nativetest(64).
  * Device test files are installed in data/nativetest(64).
  * Automatically generated configuration files and copied test binaries
    are still in the "testcases" directory.
* Change host test configuration to run test binary files
  in testcases/<mutated_module_name>/<arch_type>/<stem_name>

Ivan Lozano 88f2b1ce53 Change stdlib linkage for C libraries.
Rust C libraries cannot currently depend on dylibs. This prevents device
libraries from attempting to link the stdlib dynamically, instead using
rlibs.

Test: Simple Rust library compiles as a shared/static library.

Ivan Lozano e0833b1f5c Allow cc modules to pull in rust includes.
Make sure LinkabeInterfaces can export include dirs to cc modules. This
fixes the Rust implementation and makes sure these are pulled in for cc
modules.

Bug: 144052093
Test: cc module depending on a rust library includes dirs correctly.

Ivan Lozano 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.

Ivan Lozano 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.

Bug: 140726209
Test: Soong tests pass.
Test: Example cc_binary can include a rust shared library as a dep.
Test: m crosvm.experimental

Ivan Lozano ffee334706 Add Rust support to Soong.
Adds support to Soong for building rust modules. This currently only
supports x86_64 device and x86 linux host targets. The functionality
is sufficient to build crosvm.

Bug: 136189233
Test: Test module builds.
Test: crosvm builds.
