The not handling of frame gaps has lead to the lack of a dummy reference

lead to one SEI recovery message being skiped which had introduced a
slightly suboptimal recovery point for at least 1 h264 file compared to

Add thread-safe wrapper for get_format().
...
Just like get_buffer, get_format should not be called from a different
thread if thread_safe_callbacks is not set.

h264: Only initialize dsputil if error resilience is enabled
...
It is only used for error resilience. This allows building the
h264 decoder without dsputil, if error resilience is disabled.

h264: Integrate clear_blocks calls with IDCT
...
The non-intra-pcm branch in hl_decode_mb (simple, 8bpp) goes from 700
to 672 cycles, and the complete loop of decode_mb_cabac and hl_decode_mb
(in the decode_slice loop) goes from 1759 to 1733 cycles on the clip
tested (cathedral), i.e. almost 30 cycles per mb faster.

h264: wait for missing slices only on frames
...
The EC code does not support fields currently thus it makes no
sense to wait for these cases (which also the check doesnt handle
correctly)
