eea769df32 hevc: Use generic av_clip function, not C implementation 
hevc seems to be the only place where the C implementation
of the av_clip function is explicitly selected, precluding
platform-specific optimizations

52f2adc015 avcodec/hevc: Update the USE_SAO_SMALL_BUFFER case for the alignment requirements in FFmpeg 
Use edge emu buffers
And enable the code unconditionally

Speed difference without USE_SAO_SMALL_BUFFER and with the new code:
Decicycles: 26772->26220 (BO32),  83803->80942 (BO64)

da81cc38e8 avcodec/hevc: reduce memory for SAO 
cherry picked from commit 5d9f79edef2c11b915bdac3a025b59a32082f409

SAO edge filter uses pre-SAO pixel data on the left and top of the ctb, so
this data must be kept available. This was done previously by having 2
copies of the frame, one before and one after SAO.

This commit reduces the storage to just that, instead of the previous whole
frame.
