Ratchanan Srirattanamet facb000afe androidmedia: add NDK implementation of Android MediaCodec
This reduces the amount of Java <-> native calls, which should reduce
overhead a bit. It also paves a way to share the code between Android
and a libhybris-based backend (where GNU/Linux system uses Android
driver) in the future.
