Adds aar_import rule to Bazel along with tools needed to implement it. Currently only uses AndroidManifest.xml, classes.jar and res/ from AARs. This is sufficient for many of the AARs of Google Play Services and Android Support Repository.

The next step will be for AndroidSdkRepositoryRule to scan the SDK and generate aar_import rules for the AARs within.

The rule is not yet documented because it is not intended for end users to use it yet. We should probably support more of the features of AARs before that time. See http://tools.android.com/tech-docs/new-build-system/aar-format for all of the files that can be included in AARs.

Also note that R.txt from the AAR is intentionally ignored and regenerated based on the contents of res/. This is more correct, because the R.txt inside of an AAR can contain ids for dependencies of the AAR that are not included in res/.

See https://github.com/bazelbuild/bazel/issues/564 for discussion of supporting AARs and https://github.com/bazelbuild/bazel/issues/1745 for motivation to get it done soon.
