2018-11-22cbs_h2645: Avoid memcpy when splitting fragmentAndreas Rheinhardt
Now memcpy is avoided for NAL units that don't contain 0x03 escape characters. Improves performance of cbs_h2645_fragment_add_nals from 36940 decicycles to 6364 decicycles based on 8 runs with a 5.1 Mb/s H.264 sample (262144 runs each).

This commit adds configuration options to libvpxenc.c that can be used to enable VP8 temporal scalability. It also adds a way to programmatically set the per-frame encoding flags which can be used to control usage and updates of reference frames while encoding with temporal scalability enabled.

2018-11-18vaapi_encode_h264: Reduce SAR to valid rangeMark Thompson
The SAR of the input could have a numerator or denominator greater than 2^16 which would then be truncated to a 16-bit integer when written to the VUI parameters, giving a random result. Instead, reduce the SAR to the nearest representable fraction. Fixes #7502.

videotoolbox returns an already cropped stream which led to double cropping. this issue was introduced with the refactor of the cropping mechanism in commit 07596e4 for h264 and 000fb61 for HEVC. to fix this we set the cropping of the frame and the output frame to 0.

2018-11-12cbs_h2645: Improve performance of writing slicesAndreas Rheinhardt
Instead of using a combination of bitreader and -writer for copying data, one can byte-align the (obsolete and removed) bitreader to improve performance. With the right alignment one can even use memcpy. The right alignment normally exists for CABAC and hence for H.265 in general. For aligned data this reduced the time to copy the slicedata from 776520 decicycles to 33889 with 262144 runs and a 6.5mb/s H.264 video. For unaligned data the number went down from 279196 to 97739 decicycles. Signed-off-by: Mark Thompson <sw@jkqxz.net>

only 16b alpha is supported (not 8 bits) following official encoder, alpha data doesn't impact yuv plane quality. So the alpha data encoding is done after the yuv part. It's also avoid to loose quality in yuv part when alpha is not uniform. the alpha encoding funcs is mainly take from prores_ks encoder, except for the alpha data reorganization
