b98d334dce vaapipostproc: get "interlaced" attribute from surface proxy. 
Add new "interlaced" attribute to GstVaapiSurfaceProxy. Use this in
vaapipostproc so that to handles cases where bitstream is interlaced
but almost only frame pictures are generated. In this case, we should
not be alternating between top/bottom fields.

7b19745141 decoder: simplify output of decoded frames. 
Drop obsolete gst_vaapi_decoder_push_surface() that was no longer used.
Change gst_vaapi_decoder_push_surface_proxy() semantics to assume PTS
is already set correctly and reference count increased, if necessary.

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

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
