[Anton Khirnov]

ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Thu Jan  7 07:58:24 2016 +0100| [ee359c72ef8735122929da96006565e1558f1e55] | committer: Anton Khirnov

nvenc: rename encoders

Change 'nvenc_<codec>' to '<codec>_nvenc', which is consistent with
other similar decoders and encoders (QSV, MMAL).
