d246c18ea6 Avoid C99 variable declarations within for statements. 
We generally do not declare variables within for statements and
there are compilers that choke on such constructs.

4795362660 golomb: check remaining bits during unary decoding in get_ur_golomb_jpegls() 
Fixes infinite loop in FLAC decoding in case of a truncated bitstream due to
the safe bitstream reader returning 0's at the end.

Fixes Bug 310.

30f515091c h264: allow cropping to AVCodecContext.width/height 
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.

cac4760bf4 iac: generate codec tables as they are supposed to be 
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.

bc92214e27 vc1dsp: mark put/avg_vc1_mspel_mc() always_inline 
This ensures that these functions are inlined into the per-position
entry points, allowing constant propagation as needed for proper
optimisation.

b56825c40e mpc8: fix maximum bands handling 
In Musepack SV8 codec property tell the maximum nonzero band, but every
frame codes maximum band as a limit (i.e. strictly less than given value).
Synthesis also expects maximum nonzero band, so there's a need to convert
frame maximum band limit value.

6163d880c0 vp8: move block coeff arithcoder on stack. 
This prevents gcc from assuming that contents of it may have changed
between calls to vp56_range_get_prob(), thus preventing countless (and
unnecessary) movs. Decoding of sintel trailer goes from (avg+SG) 9.796
+/- 0.003 to 9.635 +/- 0.010.

b37d945dd4 mp3: fix start band index for block type 2 in 8kHz audio 
In hybrid frames long window part ends at 36 samples for most of the cases
but at 72 for 8kHz case. For some reason decoder assumed it's 48 or even 36
samples, which caused wrong bitstream decoding for such blocks.

l3_25207.mpg from conformance suite demonstrates it the best.
