This reverts commit 3733ab00f2a0aa6cc40b4c9cb732ffc36dd916db.
Cleanup full range YUV handling.

In FFmpeg v2.3, calling sws_setColorspaceDetails() after
sws_getContext() for YUV conversions works as desired. Now,
we can also get rid of the swscale deprecated pixel format
warnings.

Based on patches by Loic Guibert <lfdummy-
Add support for color_trc (transfer characteristic) to framework.

Frames and consumers can now have a color_trc property. Setting
color_trc on the consumer propogates to a consumer_color_trc property on
the frame.
Add support for color_trc handling to avformat module.
Add support for color_trc to Movit integration.
