mpegvideo: remove FMT_H264
h264: remove a useless svq3 condition

The svq3 decoder does not call ff_h264_frame_start() anymore.
h264_refs: cosmetics, reformat
vf_gradfun: fix uninitialized variable use

vf_hqdn3d: fix uninitialized variable use

h264: check that DPB is allocated before accessing it in flush_dpb()
pthread: unref the decoded but not returned frames on close.

Fixes memleaks when frame mt is used and the decoder is not flushed at
the end.
avframe: call release_buffer only if it is set

AVCodecContext release_buffer() shall be NULL for audio codecs using
get_buffer. The backward compatibility code hence have to check before
calling it.
vda: remove async decoder leftovers
