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.

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)

* commit '1202b712690c14f0efb06e4ad8b06c5b3df6822a':
  theora: export cropping information instead of handling it internally
  h264dec: export cropping information instead of handling it internally
  h264dec: be more explicit in handling container cropping
  hevcdec: export cropping information instead of handling it internally

This commit is a noop.

This changes the cropping behavior, when it's supposedly only meant to move
it outside of the decoder.
See https://ffmpeg.org/pipermail/ffmpeg-devel/2017-May/211239.html for the
discussion about it.
