Avoids a (incorrect) "possibly used uninitialized" warning, no measurable

88517e9f9d Extract duplicated code into a separate function. 
5% faster on Intel Atom with gcc 4.4.1 (performance is unchanged
if using av_always_inline).

e814817b74 Factor mv/ref compare code out. 
This is a hair slower (0.15% maybe) but i really dont want to have the
identical code duplicated 3 times because gcc adds odd threaded jumps with
register reshuffling and register safe/restore.

0a32508d90 Make the fast loop filter path work with unavailable left MBs.

fast code paths in each row.

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.

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

3ff0daf06d Print "Multiple frames in a packet" warning independant of CODEC_CAP_SUBFRAMES 
because CODEC_CAP_SUBFRAMES is primarely misused to hide this warning otherwise
