C++: Exposes new C++ API to Skylark

This is the API as described in https://docs.google.com/document/d/1_irTE1a8aTg8Hhf5mmlEXsFcwOw6-hz3a8FxufCyVKA/edit

This is a low level API used for rules like cc_import or for foreign C++ rules. This does not include the compilation and linking API elements.

This CL introduces the new API in a compatible way with the old. Several Skylark methods may return different object types depending on whether we are using the new or the old API. We figure out whether we are using the old or the new API from the parameters that are passed to the functions. All of this is transparent to the user from Skylark.

The old API will be deleted once cc_import and foreign rules C++ have been migrated. The internal implementation of CcLinkParams will also be deleted.

Bazel

{Fast, Correct} - Choose two

Build and test software of any size, quickly and reliably.

  • Speed up your builds and tests: Bazel only rebuilds what is necessary. With advanced local and distributed caching, optimized dependency analysis and parallel execution, you get fast and incremental builds.

  • One tool, multiple languages: Build and test Java, C++, Android, iOS, Go, and a wide variety of other language platforms. Bazel runs on Windows, macOS, and Linux.

  • Scalable: Bazel helps you scale your organization, codebase, and continuous integration solution. It handles codebases of any size, in multiple repositories or a huge monorepo.

  • Extensible to your needs: Easily add support for new languages and platforms with Bazel's familiar extension language. Share and re-use language rules written by the growing Bazel community.
