Vittorio Giovara 117b432748 lavc: Introduce AVCodec internal capabilities 
This field is designed for marking codec properties useful to lavc internals.
Two internal capabilities are added:
 - FF_CODEC_CAP_INIT_THREADSAFE: codec can be opened without locks;
 - FF_CODEC_CAP_INIT_CLEANUP: codec frees memory if initialization fails.
