Release 0.2.1 (2016-03-21)

Baseline: 19b5675

Incompatible changes:

  - Skylark rules that are available from their own repository will
    now issue a warning when accessed through @bazel_tools.
  - Set --legacy_bazel_java_test to off by default. java_test will
    now have a slightly different behaviour, correctly emitting XML
    file but, as a downside, it needs correct declaration of the
    test suite (see https://github.com/bazelbuild/bazel/issues/1017).
  - Labels in .bzl files in remote repositories will be resolved
    relative to their repository (instead of the repository the
    Skylark rule is used in).
  - Renamed proto_java_library to java_proto_library.  The former
    is now deprecated and will print out a warning when used.
  - android_sdk now compiles android_jack on the fly from
    android_jar, which means android_jar must be a jar and
    android_jack is now deprecated. The Jack tools (jack, jill,
    resource_extractor) must be specified.
  - Any project that depended on the objc_options rule will be
    broken. Can be fixed by adding attrs (infoplists,copts) directly
    to rules depending on the options.
  - .aidl files correctly require import statements for types
    defined in the same package and the same android_library.

New features:

  - Experimental Windows support is available.
  - Experimental support for writing remote repository rules in
    Skylark is available.
  - iOS ipa_post_processor attribute allows for user-defined IPA
    edits.
  - Adds a to_json method to Skylark structs, providing conversion to
    JSON format.
  - Native python rule can depend on skylark rule as long as skylark
    rule provides 'py' provider.
  - When using both --verbose_failures and --sandbox_debug, Bazel
    prints instructions how to spawn a debugging shell inside the
    sandbox.
  - add flag --sandbox_add_path, which takes a list of additional
    paths as argument and mount these paths to sandbox.

Important changes:

  - @androidsdk//:org_apache_http_legacy added for the legacy Apache
    classes for android sdk version 23 and above.
  - Genrules correctly work when used with bazel run.
  - When namespace-sandbox is run with the -D (debug) flag and
    inside a terminal, it spawns a shell inside the sandbox to aid in
    debugging when the sandboxed command fails.
  - Added --artifact to workspace generator for generating workspace
    and build file rules from artifact coodrinates.
  - Specifying --experimental_android_resource_shrinking on the
    command line will enable a resource shrinking pass on
    android_binary targets that already use Proguard.
  - J2ObjC updated to 1.0.1 release.
  - Added "root_symlinks" and "symlinks" parameters to Skylark
    runfiles() method.
  - You can no longer use objc_binary targets for the xctest_app
    attribute of an ios_test rule.
  - Enable overriding jsonnet binaries and stdlib for Jsonnet rules.
  - mount target of /etc/resolv.conf if it is a symlink.
  - Tests that failed to build because execution was halted no longer
    print their status.
  - Bazel warns if a cc rule's includes attribute contains up-level
    references that escape its package.
  - Add repository_ctx.download and repository_ctx.download_and_extract
    function.
