Add ctx argument to cc_common.configure_features

In order to migrate C++ rules to platforms, we need the access to the C++
configuration fragment in Starlark APIs. All existing APIs have already access
to it, but cc_common.configure_features doesn't. This change adds a
ctx argument to configure_features.

This is the migration needed for
https://github.com/bazelbuild/bazel/issues/7793, and is part of the effort for
https://github.com/bazelbuild/bazel/issues/6516.

If the rule doesn't depend on cpp fragment yet, you will have to add `fragments
=['cpp']` argument to the rule() call.

Note that this behavior is only available in Bazel 0.25 (to be released this month).

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.
