Hi all,

Here are various improvements to the HLS demuxer.

Notably it now works with this sample, including subtitles
(ticket #2833):

There are still some other HLS issues I have not yet fixed that I might
look at later (like #2737 and maybe #2886), but I guess it is time to
get what I have in first... :)

The non-HLS commits that the HLS commits depend on are in the
beginning of the patchset. FFmpeg builds fine between each patch.
