4645bd26aa [Encoder] Add an SSE4.2 implementation of WelsGetNonZeroCount 
Avoid touching some cache lines by using popcnt instead of table
lookups.

Also gives a speedup of ~1.4x on Haswell as compared with SSE2.

3f31aff4dc [Encoder] Add an SSE4.2 implementation of CavlcParamCal 
Use a combination of table lookups and pshufb to convert coefficients
to zero run/level format. Two 16-entry lookup tables are used for a
total of 192 bytes worth of tables. (The existing SSE2 version uses a
table of size 2048 bytes.)

Speedup is ~1.5x-3x as compared with the SSE2 version on Haswell (the
speedup is greater for input with many trailing zeros).

The use of popcnt makes it require SSE4.2. This can be replaced with
a small LUT and accumulation which would reduce the requirement to
SSSE3.

69e3fac093 Avoid reading iCountMbNumInSlice out of bounds on slice realloc 
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.

c7fcba06c7 Added support for "video signal type present" information. 
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.
