java_sdk_library does the apicheck by default

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.
