This will allow to error out immediately if incompatible options are
passed on the command line instead of running time-consuming tests.

This avoids unnecessarily linking against xlib.

Also drop a related and now redundant informative output line.

Also drop a redundant output line.

Handle the internal frame requests, which is required by the HEVC
encoding plugin.

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.

Uploading/downloading data through VPP may not work for some formats, in
that case we can still try to call av_hwframe_transfer_data() on the
child context.

Certain pixel formats (e.g. P8) might not be supported for
download/upload through VPP operations, but can still be used otherwise.

When using GPU surfaces with QSV, one needs to supply a frame allocator,
which will be invoked to pass surface pools to libmfx.
For encoding, this allocator gets invoked not only for the pool of input
frames, but also for a separate pool of (apparently) reconstructed frames
and another pool of MFX_FOURCC_P8, which on Windows needs to return
D3DFMT_P8 D3D surfaces. Those are probably used to store the encoded
bitstream on the GPU.

This format is used internally by the QSV encoder to store the encoded
bitstream.
