Generated bindings are intended to be slim translation layers, usually
consisting of nothing more than type signatures and constants.
Generally, they should also be used in exactly one location by the safe
wrapper for these bindings. By preventing them from building as
`dylib`s, we avoid the per-library overhead of these non-reused pieces
of code.
Additionally, default visibility restrict all bindgen modules to their
subpackages. This is being done both:
* to encourage use of a single safe bindings crate
* to avoid diamond dependency graphs with mixed rlib/dylib dependencies
Bug: 166332519
Test: m; Make sample module use dylib bindgen dependency, see build failure.

To allow grpc protobufs to include non-grpc protos in a singular
library, we need to allow them to be defined as part of the same module.
This CL merges the two previously distinct module types into
rust_protobuf, and adds a new property for declaring which protos
contain grpc definitions.
Bug: 172952239
Test: rust_grpcio modules converted to rust_protobuf modules and build.
Test: Example rust_protobuf module with both proto types builds.

Use WriteFileRule instead of a rule that calls printf for generating the
module source file for rust_protobuf.
Bug: 171361369
Test: rust_protobuf modules compile

Enable the RuleBuilder and RuleBuilderCommand methods to access
the BuilderContext by passing it to NewRuleBuilder instead of
RuleBuilder.Build.
Test: genrule_test.go
Test: rule_builder_test.go
Test: m checkbuild

This further emulates the rust-protobuf gen_mod_rs flag by providing
support for generating a single module containing multiple protobuf
definitions.
Bug: 171361369
Test: New Soong tests.
Test: Example module containing multiple protos works.

Allow rust_bindgen modules to define dependencies that only provide
headers and may not necessarily need to be linked in.
Bug: 161141999
Test: Soong tests pass.
Test: Example module has appropriate include flags when compiling.

The usage of the well known type Empty requires a hack in the module
above the grpc implementation, this is now the generated stem_mod.rs
This also adds additional implicit dependencies that are required by
the grpc protobuf generated code. This includes the addition of a
'header_libs' property for library dependencies which export include
paths required by protos.
We also now include both the protos and the grpcio in the library
variant via the mod_stem.rs.

Bug: 171504899
Test: m nothing
Test: Example rust_grpcio module build command includes dependencies,
include paths.

When using the grpc generator, the plugin expects to also have access to
the protobuf generator. This patch ensures that aprotoc will use the
Soong copy of the protobuf generator, rather than trying to use a
locally installed version from PATH.
Test: m nothing

Adds a new SourceProvider type to generate grpcio code from protos.
Since it's so similar to protobuf, it's basically just a different type
of rust_protobuf.
Bug: 171504899
Test: Example module compiles.
Change-Id: I9882f3ac4d4aeaae0191f2b557e9612b5c7a9ac9
* Upgrade to new protobuf-codegen; use its standard
default output without local change.
* Allow a sourceProvider to have multiple output files.
For a stem.proto file, output stem.rs and mod_stem.rs.
* New protobuf-codegen option gen_mod_rs always generates
output file named "mod.rs". To generate multiple .proto
files into the same output directory, we need to rename
mod.rs to mod_<stem>.rs.
* Instead of using the gen_mod_rs option and renaming mod.rs
to mod_<stem>.rs, we generate the same mod_<stem>.rs
directly with a simple printf command.

Test: atest -c --host --include-subdirs external/crosvm

This adds a new SourceProvider module type to handle protobuf code
generation. See the new test for an example of how to call this.
Bug: 143953733
Test: New soong tests pass.
Test: Replacing genrules in crosvm with rust_protobuf modules.
