Release 0.3.1 (2016-07-29)

Baseline: 792a9d6

Cherry picks:
   + 25e5995: Rollback of commit
              a277033.
   + 2479405: Fix NPE with unset maven_jar sha1
   + 3cf2126: Rewrite the extra action info files if the data within
              them changes.
   + 5a9c6b4: JavaBuilder: Reintroduce the -extra_checks flag.

Incompatible changes:

  - Removed predefined Python variable "generic_cpu".
  - Skylark rules: if you set "outputs" or an attribute to a
    function, this function must now list its required attributes as
    parameters (instead of an attribute map).
  - The host_platform and target_platform entries are not written to
    the master log anymore.
  - Bazel requires Hazelcast 3.6 or higher now for remote execution
    support, because we upgraded our client library and the protocol
    it uses is incompatible with older versions.

New features:

  - LIPO context (--lipo_context) can now also be a cc_test (in
    addition to cc_binary)

Important changes:

  - If --android_crosstool_top is set, native code compiled for
    android will always use --android_compiler and not --compiler in
    choosing the crosstool toolchain, and will use --android_cpu if
    --fat_apk_cpu is not set.
  - Add --instrument_test_targets option.
  - apple_binary supports a new platform_type attribute, which, if
    set to "watchos", will build dependencies for Apple's watchOS2.
  - objc_binary now supports late-loaded dynamic frameworks.
  - Native Swift rules no longer pull in module maps unconditionally.
    Use --experimental_objc_enable_module_maps for that.
  - Merged manifests are guaranteed to have the application element
    as the last child of the manifest element as required by Android
    N.
  - The Android manifest merger is now available as an option for
    android_binary rules. The merger will honor tools annotations in
    AndroidManifest.xml and will perform placeholder substitutions
    using the values specified in android_binary.manifest_values. The
    merger may be selected by setting the manifest_merger attribute
    on android_binary.
  - The progress message would not clear packages that need to be
    loaded twice.
  - Remove warning for high value of --jobs.
  - Use the correct build configuration for shared native deps during
    Android split transitions.
  - When building ObjectiveC++, pass the flag -std=gnu++11.
  - use xcrun simctl instead of iossim to launch the app for "blaze
    run".
  - Glob arguments 'exclude' and 'exclude_directories' must be named
  - Bazel no longer regards an empty file as changed if its mtime has
    changed.
