This currently doesn't do anything, but will be used later for hwaccel
filters and libavutil.

Doing slice_end - slice_start is unsafe and can lead to undefined behavior

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.

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.
