Release 0.4.2 (2016-11-30)

Baseline: 2a26c3c

Cherry picks:
   + a79581e: Add gpu compile support to MSVC wrapper script
   + 4c67807: Improve reliability/performance of Bazel downloads
   + ed7ced0: Support multiple mirror URLs for external repos

Incompatible changes:

  - Callback functions in Skylark no longer support the cfg
    parameter. This is a cleanup and only affects the signatures of
    callbacks, since the parameter hasn't been set since September
    2016.

Important changes:

  - Prevent spurious recompiles, e.g. with changing --test_arg.
  - proto_library now produces a descriptor set, when built on the
    command-line.
  - Add ctx.coverage_instrumented function to Skylark, to indicate
    whether a specific targets should be instrumented for code
    coverage data collection.
  - Use --loading_phase_threads to control the number of threads used
    during the loading/analysis phase.
  - Structs in Skylark are tested for structural equality instead of
    reference equality.
  - Skylark implementations of http_archive, new_http_archive, and
    http_file.
  - Labels like "@foo//:foo" can now be written as "@foo" in build
    files
  - Alias proto_library's produce a descriptor set that contains all
    srcs of its dependencies.
  - External downloads now retry with exponential backoff and support
    gzip content-encoding.
  - proto_library supports strict proto deps.
  - A urls attribute has been added to repository rules to support
    multiple mirror URLs for reliably downloading files.
  - Top level @androidsdk support library targets have been replaced
    by @androidsdk//<group id>:<artifact id>-<version> for Android
    SDK Support and Google Play Services libraries.
