When the sdk_version or LOCAL_SDK_VERSION is not current or
TARGET_BUILD_APPS is not null, module will use the prebuilt
libraries. For this, prebuilt libraries are supported in
prebuilt_api.go

droiddoc now supports apicheck. java_sdk_library uses it to
automatically perform apichecks against the not-yet-release API and
the latest-released API.
A module type prebuilt_apis is added. It finds api txt files and creates
filegroup modules so that it can be referenced from java_sdk_library
across the module boundary.
