Move asm routines to common. Delete obsolete decoder routines.
Use wider routines where applicable.
~1.07x overall faster decode on a quick 720p30 4Mbps test on Haswell.

Prior to 7bcb3ba4f4abf18a,
pCurLayer->sLayerInfo.pSliceInLayer[uiSliceIdx].iCountMbNumInSlice
was read after setting pCurLayer->sLayerInfo.pSliceInLayer to
the newly allocated, larger array. After this commit, it is read
before the array has been switched, and thus is read from the
old array (which only holds elements up to iMaxSliceNumOld, not
up to iMaxSliceNum).
This fixes reads out of bounds, and crashes in the test suite.
The "Video signal type present" information is written to the output
video file when it is created, and later is used by the decoder to
properly decode the compressed video data. The saved attributes
are:
- format type (PAL, NTSC, etc.)
- color primaries (BT709, SMPTE170M, etc.)
- transfer characteristics (BT709, SMPTE170M, etc.)
- color matrix ((BT709, SMPTE170M, etc.)
These modifications allow the client to specify these attributes
and, if specified, makes sure they are written to the output file.
