1189af4292 h264: update avctx width/height/pix_fmt when returning frame 
Inconsistencies between the dimensions/pixel format of avctx and the
frame can confuse API users.
For example this can crash the demuxing_decoding example.

Back up the previous values and restore them, when decoding the next
frame. This is necessary, because these can be different between the
returned frame and the last decoded frame.

aef0e0f009 avcodec/h264_slice: Use AVFrame diemensions for grayscale handling 
The AVFrame values are closer to the AVFrame bitmap changed instead of
the AVCodecContext values, so this should be more robust

11f024ef0a h264: move freeing the escaped RBSP buffer to free_context()

ee62b364be h264: eliminate ff_h264_set_parameter_from_sps() 
That function currently does two things -- reinitializing the DSP
contexts and setting low_delay based on the SPS values.

The former more appropriately belongs in h264_slice_header_init(), while
the latter only really makes sense in decode_slice_header().

The third call to ff_h264_set_parameter_from_sps(), done immediately
after parsing a new SPS, appears to serve no useful purpose, so it is
just dropped.

Also, drop now unneeded H264Context.cur_chroma_format_idc.

a6cd154463 h264: move the DPB init/uninit to init_context()/free_context() 
Currently, the DPB is initialized in alloc_tables() and uninitialized in
free_tables(), but those functions manage frame size-dependent
variables, so DPB management does not logically belong in there.

Since we want the init/uninit to happen exactly once per the context
lifetime, init_context()/free_context() are the proper place for this
code.

f4f3065c69 h264: remove bogus YCgCo warning message 
YCgCo decoding works just fine. It depends on the API user what is done
with the output. Some API users might support it, some not. Some users
might support it under certain circumstances only.

It is not the job of the decoder to print this message. If the API user
supports it, this message is extremely unhelpful.
