wm4 532b23f079 videotoolbox: add hwcontext support 
This adds tons of code for no other benefit than making VideoToolbox
support conform with the new hwaccel API (using hw_device_ctx and
hw_frames_ctx).

Since VideoToolbox decoding does not actually require the user to
allocate frames, the new code does mostly nothing.

One benefit is that ffmpeg_videotoolbox.c can be dropped once generic
hwaccel support for ffmpeg.c is merged from Libav.

Does not consider VDA or VideoToolbox encoding.

Fun fact: the frame transfer functions are copied from vaapi, as the
mapping makes copying generic boilerplate. Mapping itself is not
exported by the VT code, because I don't know how to test.

Martin Vignali 2c6179aa82 libavcodec/exr : simplify reorder_pixels 
reorder_pixels is call by rle_uncompress and zip_uncompress
with size == uncompress_size

uncompress_size is a multiple of 2 (because exr store data
in half, float, or uint32)
