This was only used in hevc muxing code so far.
This makes the return values match what get_se_golomb returns for
the same bitstream reader instances.
The logic for producing a signed golomb code out of an unsigned one
was based on the corresponding code in get_se_golomb, which operated
directly on the bitstream reader buffer - not on the equivalent
return value from get_ue_golomb.

unsigned int buf = get_ue_golomb_long(gb);
if (buf & 1)
- buf = -(buf >> 1);
+ buf = (buf + 1) >> 1;
else
- buf = (buf >> 1);
+ buf = -(buf >> 1);
return buf;
