a740cae4a0 avcodec/dcadec: remove unsignedness from constant 
POSIX gurantees >=32bit so it all fits in signed int
Also >=32bit ints are assumed througout the codebase

f6577bd9cf huffyuvdec: use unsafe bitstream reader 
The reader reads in chunks of 11 bits at most, and at most 3 times. The unsafe
reader therefore may read 6 chunks instead of 1 in worst case, ie 8 bytes,
which is within the padding tolerance.

The reader ends up being ~10% faster. Cumulative effect of unsafe reading and
code block swapping on 3 sequences is for 1 thread, decoding time goes from
23.3s to 19.0s.

29f427c239 huffyuvdec: remove somewhat deprecated code 
The old code was reserving the 0xFFFF entry to represent an inexisting
entry/codeword. These entries are now detected through their length
being <= 0. As this entry is often used for the residuals (-1,-1), which
should be among the most frequent, it is particularly important to not
reserve it.

9dc1791977 huffyuvdec: swap code blocks 
The effect is not really deterministic, as it seems to be a combination
on x86_64 of fewer registers used, different jump offsets and, for all
archs, of likely branches.

Speedup is around 15%.
