a8cbe5a0cc h264_ps: export actual height in MBs as SPS.mb_height
Currently, SPS.mb_height is actually what the spec calls
PicHeightInMapUnits, which is half the frame height when interlacing is
allowed. Calling this 'mb_height' is quite confusing, and there are at
least two associated bugs where this field is treated as the actual
frame height - in the h264 parser and in the code computing maximum
reordering buffer size for a given level.

Fix those issues (and avoid possible future ones) by exporting the real
frame height in this field.

f638b67e57 h264: move the parameter set definitions to a new header file
The PS parsing code is independent from the decoder, so it makes more
sense for it to have its own separate header.
