Porting the hlsdemux work in issue 698155 to 1.x

[Duncan Palmer]

Hi Arnaud,

Whilst I think your work will be quite useful for me, it doesn't
include support for i-frame playlists, which is a feature I need.
However, I see that Andoni's branch requires an I-frame playlist to be
present to allow seeking, which seems a bit of a feature regression...
It's interesting what you say about performance - will have to try it
and see how I go. Andoni's branch also uses buffer lists, but not to
hold the playlist. I'm not sure of the significance of that...

Right now, I don't need support for alternative renditions, but I may
down the track. I do wonder how much use these see in practice - do
people typically use alternative renditions, or do they use
alternative audio tracks and dvb subs in the transport stream instead?
