7a20656474 cbs_h265: Add a lot more SEI parsing support 
Supports both prefix and suffix SEI, decoding all of the common SEI
types and some more obscure ones.  Most of this is tested by the
existing tests in fate.

ee47ac97d7 cbs_h2645: Improve performance of writing slices 
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.

da6db843b8 cbs_h2645: Allocate all internal buffers with padding 
Any of these buffers (for both H.264 and H.265) might reasonably be
parsed using the bitstream reader, so include padding on all of them.

3143fe34f6 cbs_h264: Actually decompose end-of-sequence NAL units 
64c50c0e97 declared support for decomposing
them but omitted to implement it; this adds an implementation.

Also do the same for end-of-stream NAL units, since they are equivalent.

56ed011692 cbs_h265: read/write HEVC PREFIX SEI 
Similar to H264, cbs_h265_{read, write}_nal_unit() can handle HEVC
prefix SEI NAL units. Currently mastering display colour volume SEI
message is added only, we may add more SEI message if needed later

df3a2ff767 avcodec/cbs: use a reference to the assembled CodedBitstreamFragment buffer when writing packets 
This saves one malloc + memcpy per packet

The CodedBitstreamFragment buffer is padded to follow the requirements

ce5870a3a8 cbs: Refcount all the things! 
This makes it easier for users of the CBS API to get alloc/free right -
all subelements use the buffer API so that it's clear how to free them.
It also allows eliding some redundant copies: the packet -> fragment copy
disappears after this change if the input packet is refcounted, and more
codec-specific cases are now possible (but not included in this patch).
