a12d3188cb h264: use a smaller struct for the ref lists 
There is no need to store a whole H264Picture, with a full AVFrame
embedded in it. This should allow getting rid of the embedded AVFrame
later.

  h264_refs: make sure not to write over the bounds of the default ref list

Conflicts:
	libavcodec/h264_refs.c

This condition should be impossible and was checked for by asserts.
the asserts are moved up in this merge to gurantee that no out of array
access can happen even if the state is "impossible".
Also if such impossible states could somehow be created, that should
be dealt with and not silently ignored.
