bc7beb6574 vc2enc: calculate the minimum slice size only once 
This commit moves the minimum bits per slice calculations outside of the
rate control function as it is identical for every slice.

2b811e4605 vc2enc: halve allocated table size, refactor and optimize quantization 
Since coefficients differ only in the last bit when writing to the
bitstream it was possible to remove the sign from the tables, thus
halving them. Also now all quantization is done in the unsigned domain
as the sign is completely separate, which gets rid of the need to do
quantization on 32 bit signed integers.

Overall, this slightly speeds up the encoder depending on the machine.
The commit still generates bit-identical files as before the commit.

14f7a3d55a lavc/lavf: transmit stream_id information for mpegts KLV data packets 
This allows to copy information related to the stream ID from the demuxer
to the muxer, thus allowing for example to retain information related to
synchronous and asynchronous KLV data packets. This information is used
in the muxer when remuxing to distinguish the two kind of packets (if the
information is lacking, data packets are considered synchronous).

The fate reference changes are due to the use of
av_packet_merge_side_data(), which increases the size of the output
packet size, since side data is merged into the packet data.
