hwcontext: Hardware frame mapping

Multimedia / Libav - Mark Thompson [jkqxz.net] - 3 November 2016 18:49 UTC

Adds the new av_hwframe_map() function, which allows mapping between hardware frames and normal memory, along with internal support for implementing it.

Also adds av_hwframe_ctx_create_derived(), for creating a hardware frames context associated with one device using frames mapped from another by some hardware-specific means.
