Currently it always shows "Selected ratecontrol mode is not supported
by the QSV runtime. Choose a different mode", but sometimes it is not

Hypothetical Reference Decoding (HRD) model assumes that data flows
into a buffer of the fixed size BufferSizeInKB with a constant bitrate.
Smaller BufferSizeInKB means smaller frame size variations,
but more difficult to maintain HRD.

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
implementation, at

edfa#diff-7d84a34d58597bb7aa4b8239dca1f9f8). Already applied to

This will allow implementing the allocator more fully, which is needed
by the HEVC encoder plugin with video memory input.

For encoding, this avoids modifying the input surface, which we are not
allowed to do.
This will also be useful in the following commits.

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.
