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.

The reference encoder limits it to 64, but testing revealed that there
is absolutely no difference for indices above 50 in amount of zeroed
coefficients.

Also bench a smaller buffer. This drastically reduces --bench runtime
and reports smaller, more readable numbers.

Improves streaming compatibility with Windows Media Services. Also tested for
compatilbility in Windows Media Player, Windows Media ASF Viewer and VLC.

This version of the patch only writes exclusion among audio streams, therefore
choosing a subtitle language should be possible independently of audio language.

ffserver&ffm: Fixed issues preventing ffserver write_index and files_size from being set correctly which was breaking ffserver streaming.

I discovered that ffserver streaming was broken (it seems like it has been since 20th November) and I opened a ticket for this (https://trac.ffmpeg.org/ticket/5250 <https://trac.ffmpeg.org/ticket/5250>).

I spent yesterday learning git bisect (with the kind help of cehoyos) to painstakingly track down the cause. This was made more difficult due to the presence of a segfault in ffserver during the period where the bug was introduced so I first had to identify when and how that was fixed and then retrospectively apply that fix again for each step of the second git bisect to find the actual bug.

Anyway, the fruits of my labour are the innocent looking patch below to correct a couple of typos and define a valid range for two variables.

Avoid invalid memory read/crash when frame offset >= 0xfffffff8.

Fix cases where unknown data (data beyond p->buf_size) could produce a
higher ico probe score than if the unknown data was known and valid.
For example:
    Header:  OK, 2 frames
    Frame 0: Unknown (offset points beyond end of probe buffer)
    Frame 1: Invalid
Previously this example had a score of 25, even though the score would
be 1 if the unknown frame was known to be valid or 0 if it was known
to be invalid.  For this example the score is now 1.

Codec options of streams detected during avformat_find_stream_info are not set
therefore without this patch we initialize the encoders with decoder info
based on decoders without options.

This cause problems for probed DVB teletext streams where
avctx->subtitle_header depend on the txt_format setting.
