Otherwise we'll wait until buffers are completely processed downstream,
which might take quite some time.

b7ef52c515 hlsdemux: Segfaults if playlist has no media files 
hlsdemux causes a null pointer dereference if the media playlist
does not contain any media files. The gst_m3u8_client_get_duration
function assumes that demux->client->current->files is valid when
computing duration.

gst_m3u8_client_update needed to be modified to check for the
case of downloading an M3U8 file that doesn't contain any media
files, and returning an error to gsthlsdemux.c

This bug can be reproduced by creating a master m3u8 file that
contains one media playlist that points back to the master m3u8
file.  For example create a file called bug725134.m3u8:
  #EXTM3U
  #EXT-X-VERSION:4
  #EXT-X-STREAM-INF:PROGRAM-ID=1, BANDWIDTH=1251135, CODECS="avc1.42001f mp4a.40.2", RESOLUTION=640x352
  bug725134.m3u8

874af7db4e hlsdemux: Init and clear a mutex 
GLib initialises automatically for us for some reason... but of course
does not clear the mutex once the demuxer is destroyed.

161254d7c0 hlsdemux: Fix parsing of CODECS and RESOLUTION 
hlsdemux does not check for the '"' character in #EXT-X-STREAM-INF
attributes. The CODECS parameter is an example of an attribute
that might use the '"' symbol and might contain a ',' character
inside this quoted string.

For example: CODECS="avc1.77.30, mp4a.40.2"

hlsdemux does not correctly parse the RESOLUTION attribute, it
assumes that an '=' character is used to delineate the width
and height values, but the HLS RFC states that a 'x' character
must be used as the delimiter between width and height.

91775a1abd hlsdemux: Fix for URLs that contain a '/' in the query parameter 
If the URL for the master manifest files contains a '/' character
in the query parameter (for example
http://example.net/1054559_h264_1500k.mp4/master.m3u8?acl=/*1054559_h264_1500k.mp4),
hlsdemux is incorrectly converting the relative URLs of the media
playlists in to absolute URLs. It is incorrectly using the last '/' it
finds in the URL. According to RFC3986 the '/' character is allowed in
the query part of the URL.

b3a7242910 hlsdemux: Keep track of timestamps by adding them up during playback 
...instead of adding them from the start of playlist every time. This
among other things fixes timestamps for live streams, where the playlist
is some kind of ringbuffer of fragments and thus adding from the beginning
of the playlist will miss the past fragments.

a51116add3 hlsdemux: Refactor threading and downloading 
We now download fragments as fast as possible and push them downstream
while another thread is just responsible for updating live playlists
every now and then.

This simplifies the code a lot and together with the new buffering
mode for adaptive streams in multiqueue makes streams start much faster.

Also simplify threading a bit and hopefully make the GstTask usage safer.
