Purpose: qsvenc: make sure that interlaced encoding works. Also,
reduce the vertical alignment constraint when possible to reduce
memory usage.
Note: Most of this code used to be present in ffmpeg and was
eliminated in revision 1f26a23 on Oct. 31, 2016 (qsv: Merge libav

Merged as-at libav 398f015, and therefore includes outstanding
skipped merges 04b17ff and 130e1f1.
All features not in libav are preserved, and no options change.
The b_frame_strategy option is only used by mpegvideoenc, qsv, x264, and
xavs, while b_sensitivity is only used by mpegvideoenc.
These are very codec-specific options, so deprecate the global variants.
Set proper limits to the maximum allowed values.
