Migration have been done for these ffmpeg/libav changes:
2013-12-11 - 29c83d2 / b9fb59d,409a143 / 9431356,44967ab / d7b3ee9 - lavc 55.45.101 / 55.28.1 - avcodec.h
av_frame_alloc(), av_frame_unref() and av_frame_free() now can and should be
used instead of avcodec_alloc_frame(), avcodec_get_frame_defaults() and
avcodec_free_frame() respectively. The latter three functions are deprecated.
2012-10-08 - ae77266 / 78071a1 - lavu 51.74.100 / 51.42.0 - pixfmt.h
Rename PixelFormat to AVPixelFormat and all PIX_FMT_* to AV_PIX_FMT_*.
To provide backwards compatibility, PixelFormat is now #defined as
AVPixelFormat.
Note that this can break user code that includes pixfmt.h and uses the
'PixelFormat' identifier. Such code should either #undef PixelFormat
or stop using the PixelFormat name.
FFmpeg now requires that frames allocated with avcodec_alloc_frame are
freed with avcodec_free_frame.

The 'sysctl' syscall has been strongly deprecated on Linux for ages.
Currently, on old architectures it will spam syslog whenever used, and on
newer ones it's missing from the headers altogether. Opencv has migrated
away on Linux already, but #includes were left lingering. This commit
removes them on non-__APPLE__, unbreaking x32 (and probably others).
