This optimization improved h264 decoding performance about 4%(from 74fps to 77fps, tested on loongson 3A3000).

This checks the value exactly for intra frames and checks it against a
minimum for inter frames as they can be variable.

decomp_len is used in raw frames, so it should not be left at the value from
whatever was decoded previously (which may be any other frame)

Combined 1st and 2nd loop into one inline asm in function ff_vc1_inv_trans_8x8_mmi to
reduce memory operation, and made some small optimization in ff_vc1_inv_trans_4x8_mmi.

Fixes high memory usage and prevents over allocation of the frames via
proper unref.
Can be checked as:
-hwaccel qsv -c:v h264_qsv -i ../h264-conformance/CANL2_Sony_E.jsv -c:v
h264_qsv -b:v 2000k -y qsv.mp4
For example bitdepth should be printed as 10 instead of 0A. Thanks to Hendrik Leppkes for pointing this out

Fixes ticket #5654.
The linesize can be greater than the minimum required. This copies the
frame taking linesize into account.
