  AvFormatDecoder: Flush H264 streams to release frames context

- on stream changes, a second hardware frames context was being created
before the first was released because the codec context still held
references to the frames context for reference frames (not relevant for
MPEG2).
- should fix H264 concurrency on both VAAPI and VDPAU
- a similar fix is necessary for NVDEC, MediaCodec and VideoToolBox
(which use device contexts)
- N.B. there is no fix for HEVC for any codec (which will have the same
issues) as we have no HEVC parser to detect stream changes.
