lavf: add some basic documentation of the muxing process

Previously these type of streams were not returned even if wanted stream was
set to a stream of such. Now they are only skipped if they are not wanted
streams.
Fixes ffplay -sst <stream number> out.ts where stream number is a *_IMPAIRED stream.

Since 2007, the Xiph.org Foundation recommends that .ogg only be used
for Ogg Vorbis audio files.
Source: http://wiki.xiph.org/index.php/MIME_Types_and_File_Extensions
However we only do it if we have libvorbis available because the
built in vorbis encoder is not as good.

If a special comment packet shows up in the middle of the stream, we
should extract it out into the vorbis stream metadata dictionary.
Also, if there is metadata in the packet on the way in, it might linger
since we only add data to the dictionary causing stale metadata to be
inserted into the stream. Instead, clear it to remove any doubt about
what is new and old.

Currently, if there are multiple 'performer' tags, the last one is the
only one which appears. Instead, join them with a semicolon.

Currently ff_interleave_packet_per_dts() waits until it gets a frame for
each stream before outputting packets in interleaved order.
Sparse streams (i.e. streams with much fewer packets than the other
streams, like subtitles or audio with DTX) tend to add up latency and in
specific cases end up allocating a large amount of memory.
Emit the top packet from the packet_buffer if it has a time delta
larger than a specified threshold.

Even though the most common framerate for RoQ is 30fps,
the format supports other framerates too.

This is the solution we've been using in XBMC for over 2 years for dvd still frames.
The problem is that the demuxer asks for probing of the codec in the mpeg stream.
This causes lavf to read the whole menu structure into internal buffers.
After which, it won't read from input stream anymore and no events triggers.

If someone has an idea on how to fix this nicer, that would be very welcome
but the stream contains several PMTs with just one of the 2 streams at the start
