Import protobuf-codegen-2.14.0
* Add OWNERS, Android.bp, and README.android.
* Hard code version number in src/lib.rs for now.
It could be in a smarter update_package.sh to get the
new version number from Cargo.tom. But until then,
the difference in lib.rs will be caught and fixed manually.
* Rename protoc_gen_rust to protoc-gen-rust for aprotoc plugin.
