2c6cf13940 wavpack: Reset internal state on corrupted blocks 
wavpack_decode_block() supposes that it is called back with the exact
same buffer unless it has returned with an error. With multi-channels
files, wavpack_decode_frame() was breaking this assumption.

* hexene/stagefright:
  libstagefright: start decode_thread() only after decode_frame() is called at least once.
  libstagefright: mark the dummy frame as keyframe.
  libstagefright: limit the output queue size
  libstagefright: return EOS if CustomSource::read() is called after decode_thread() returns
  libstagefright: set the correct frame size

a85996d834 libstagefright: start decode_thread() only after decode_frame() is called at least once. 
This prevents the situation where EOS is passed as the first frame to the
h/w decoder and thus avoids a potential crash.

fedbf9177c libstagefright: mark the dummy frame as keyframe.

14c21c1ff5 H264: Only wait before triggering ff_thread_setup_complete() until the next slice that contains a start-of-field/frame macroblock 
This allows concurrent decoding of the last field/frame, rather than
only the last slice, of data packets with multiple NAL units packed
together.

This will fix the slowdown reported in e.g. bug 52.
