980bcc554d Unroll main loop so the edge==0 case is seperate. 
This allows many things to be simplified away.
h264 decoder is overall 1% faster with a mbaff sample and
0.1% slower with the cathedral sample, probably because the slow loop
filter code must be loaded into the code cache for each first MB of each
row but isnt used for the following MBs.

7e2ef1b9e1 Fix possible crashes in mlp parser, it tries to go back 7 bytes after 
finding the 4-byte signature.
Add a check that ignores the signature if we do not have enough previous
data to go back at least 7 bytes.

9f72b23c5c Revert Revision: 21362 
Log:
	Set CODEC_CAP_SUBFRAMES for adpcm decoders

	This makes ffmpeg stop printing millions of
	  Multiple frames in a packet from stream 0
	when decoding adpcm.
Reason: adpcm has no subframes, the flag does not belong there

b52fcba9cd Fix decoding ATI VCR2 codec, sample in 
samples/V-codecs/ATI-VCR12/ATI/VCR2test.avi
Software decoding was broken since r8865, when two new context variables
were added, but not initialized in vcr2_init_sequence().
Another such context variable was added in r18381.
