[FFmpeg-devel] [PATCH] hwcontext: add a QSV implementation

[nablet developer]

patch is taken from libav project, authored by Anton Khirnov <anton at khirnov.net>
https://lists.libav.org/pipermail/libav-devel/2016-May/077126.html
the only differences from original libav patch:
1) replaced CONFIG_LIBMXF with CONFIG_QSV to match the rest of ffmpeg sources
2) changed copyright headers to match ffmpeg standard

this patch adds Intel QuickSync Video hardware context implementation to libavutil,
in same manner as other hardware context implementations like CUDA, VAAPI, etc.
this context will be used and shared by various Intel QuickSync Video decoders and
encoders component (like qsv_h264), as well as VPP filter.
