movenc/isom: update vpcC box to version 1.0 of the specification
...
This brings our generation of the vpcC box up to date to version 1.0
of the VP Codec ISO Media File Format Binding.
Specifically, color/transfer properties are now written with values
based on ISO/IEC 23001-8, which is the same reference specification the
AVColor* enumerations are based on.

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.
