a19c689dfa dashdemux: detect end-of-period correctly 
Detect end of period when there are no more buffers on any of the
streams

3a055ac2d1 dashdemux: Use the smallest queue value to define buffering state 
The smallest queue should be used to prevent blocking the download
thread when a stream has too much data buffered, leaving the other
streams starving from fragments

9777fc5cb5 dash: fix parsing of streams to get correct fragment durations 
Use the current stream base time instead of the 0th stream base time
to get default duration for fragments.

54542a6000 dashdemux: block waiting for buffers instead of busy wait 
Make the streaming loop block waiting for buffers on the queues instead
of busy waiting eating cpu continuously on a queue length check

80c6973319 dashdemux: fix seeking on multiple streams 
Each stream has its own durations and timestamps, the fragment number
is different for each stream when seeking, so the seek has to be done
for all streams, rather than on a single stream and propagated to
others

7330225ac8 dashdemux: Replace GQueue by GstDataQueue 
GstDataQueue has proper locking and provides functions to limit the
size of the queue. Also has blocking calls that are useful to
our multithread scenario in Dash.

27b1abbda3 dashdemux: move the buffers queues to the streams 
Store the buffers separately for each stream, this is clearer than
having a queue with a list of buffers. It also allows easier selection
of buffers to push in later refactors

f27bb684f7 dashdemux: Remove timing code that delays pushing of fragments 
Fragments should be pushed ASAP as downstream should be responsible for
doing the syncrhonization and proper buffering.

This has the great side effect of fixing most of the seeking A/V sync issues.

d058a7f2b2 plugin: register as dashdemux instead of fragmented

cbebb01f23 dashdemux: use new gst_mpd_client_get_next_fragment_duration API 
This fixes build that has been broken by commit
fb9aeac6552021b176a4c4bd07265e02a0b70e0f.

gst_mpd_client_get_target_duration has been removed, and
gst_mpd_client_get_next_fragment_duration should be used instead.

9387365fc9 dashdemux: reworked the API to retrieve fragment timestamp, fragment duration and media presentation duration 
This was necessary to support variable-duration Fragments.

in the new API:
- gst_mpd_client_get_current_position returns the timestamp of the NEXT fragment to download;
- gst_mpd_client_get_next_fragment_duration returns the duration of the next fragment to download;
- gst_mpd_client_get_media_presentation_duration returns the mediaPresentationDuration from the MPD file;

also there is a new internal parser function:
- gst_mpd_client_get_segment_duration extracts the constant segment duration from the MPD file
(only used when there is no SegmentTimeline syntax element in the current representation)

In gst_mpd_client_get_next_fragment, we set the timestamp/duration of the fragment just downloaded
copying the values from the corresponding GstMediaSegment.

TODO: rework SEEKING to support seeking across different Periods.

- do not add a spurious '$' when building an URL from a template like "$Bandwidth$/init.mp4v"

255eb4b161 mssdemux: use streams bitrate individually 
connection setup times seem to matter when measuring the download
rate of different streams. Streams with longer fragments have a
*relatively* lower connection setup time and achieve higher bitrates.

Using the average seems unfair here, so use each stream's measured bitrate
to select its best quality option.

aa1713068a mssdemux: implement live streams handling 
Live streams force the demuxer to keep reloading the Manifest from
time to time, as the new fragments are being added as they are recorded.
The demuxer should also try to keep up and detect when it had to skip
fragments, marking the discont flag when that happens.

Curiously, the spec doesn't seem to mention when/how a live stream is supposed
to end, so keep trying downloads until the demuxer errors out.
