h264: allow cropping to AVCodecContext.width/height
The above commit is not taken as is as its buggy (incorrect handling of
the interlaced case) and didnt apply cleanly.
Fixes ticket156

Override the frame size from the SPS with AVCodecContext values
if the latter specify a size smaller by less than one macroblock.
This is required for correct cropping of MOV files from Canon cameras.

With complex filters, an output can come from any input,
or several inputs, including inputs of a different type.
Copying the codec parameters from the first input with
the same type does not make any sense.
This does not change anything for simple 1->1 filters,
as source_index is set in that case.
Unlike its predecessor, Indeo Audio codec generates tables depending on
sampling rate. Previously decoder used pre-generated tables for 22050 Hz
which obviously doesn't work with other frequencies.
Many thanks to Maxim Poliakovsky for providing all needed information
for this.

This fixes: ffplay -f lavfi -i cellauto
This was a regression since factorizing the filter code with ffmpeg.
