avcodec: Remove libstagefright
It serves absolutely no purpose other than to confuse potentional Android developers about how to use hardware acceleration properly on the the platform. The stagefright "API" is not public, and the MediaCodec API is the proper way to do this. Furthermore, stagefright support in avcodec needs a series of magic incantations and version-specific stuff, such that using it actually provides downsides compared just using the actual Android frameworks properly, in that it is a lot more work and confusion to get it even running. It also leads to a lot of misinformation, like these sorts of comments (in [1]) that are absolutely incorrect.
