video: mac hardware acceleration

Browse Source 
Adds VideoToolbox and VDA hardware accelerations. VideoToolbox
supports H.264, H.263 and MPEG4, while VDA only supports H.264.

VDA is implemented in case libav is used instead of FFmpeg, as
only the latter implements VideoToolbox. This being said, Ring
will prefer VideoToolbox.

VideoToolbox is OSX 10.8+ and iOS 8+. VDA is OSX 10.6.3+.

Both have their respective configure switches.
