3e1d235c1a decoder: fix possible leak of VA surfaces. 
Under some circumstances, we could have leaked a surface, thus not
releasing it to the pool of available surfaces in the VA context.
The strategy is now to use a proxy earlier and automatically ref/unref
whenever necessary. In particular, during the lifetime needed for FFmpeg.

61ae27d84c Split decoder creation with actual resources allocation 
and codec setup (probe). This fixes a memory leak (avctx, pctx)
on destroy and most interestingly makes it possible to
detect unsupported codecs.

0d7164c96c Flush stream only if avcodec_decode_video() read something. 
Otherwise, we might still have to seek into the stream.
i.e. keep the data longer.

a203d19a35 Add initial (multithreaded) decoder based on FFmpeg. 
There are tons of bugs left:
- Decoder API not nice enough with error conditions
- FFmpeg parser is sometimes broken
- Packets queue can be lost
