Release 0.4.1 (2016-11-21)

Baseline: 9a796de

Cherry picks:
   + 88bfe85: Description redacted. -- MOS_MIGRATED_REVID=139219934
   + b09ea94: Rollback of commit
              a3f5f57.

New features:

  - android_library now has a "exported_plugins" attribute just like
    java_library
  - Use --strict_system_includes to apply hdrs_check=strict also to
        cc_library.includes, even if sandboxing is disabled.
  - Bazel on Windows: java_binary can now be the executable of
    Skylark rule actions (ctx.action's executable argument)
  - Packages are defined in BUILD.bazel as well as BUILD files.

Important changes:

  - getattr()'s 3-arg form no longer raises an error when the
    retrieved field is a built-in method.
  - --apk_signing_method default changed to v1. Android APKs are now
    signed with the new ApkSignerTool by default.
  - New rule: proto_lang_toolchain(), to support LANG_proto_library
    rules on multiple platforms.
  - Fix for Android clang++ std::stack segfault on 32bit x86. See
    https://code.google.com/p/android/issues/detail?id=220159
  - Default android_manifest_merger is now "android" which uses the
    official Android manifest merger.

    ifest-merger
  - Do not propagate aspect to its own attributes when using '*'.
  - Comparing sets (`if set1 < set2:`) is not allowed anymore in
    Skylark because it didn't work correctly anyway.
  - When --experimental_extra_action_top_level_only, Bazel reports
    extra-actions for actions registered by Aspects injected by a
    top-level rule (approximately).
  - Blacklists for proto_lang_toolchain() no longer have to be
    proto_library's.
  - Extra actions now contain aspect-related information.
  - Fix slicing bug where "abc"[:-4:-1] would give wrong answer
