a53fd87508 dashdemux: mpd parsing: fix query parameter parsing 
Try harder to detect URL parameters and split them to accomodate
the fragment url in the concat:

base-url + fragment-url + url-parameters

737d328bb5 dashdemux: properly reset stream status after a flush 
The stream eos/end of period status must also be reset after a flushing
seek. This makes seeking after EOS work.

460542daaf dashdemux: add a downloadrate utility

94dcb60127 dashdemux: change bitrates based on the stream bitrate 
Do not use a global bitrate as the sizes of the fragments matter
when calculating the download rate as the connection setup time is
also being taken into the download duration, a smaller fragment
will have a lower bitrate than a larger one.

This avoids switching the bitrates for streams frequently because
of bitrate mismatches

83c0e1e25d dashdemux: download the next fragment with smaller timestamp 
Instead of downloading 1 fragment per stream per download loop,
select the stream with the earlier timestamp and get a fragment
only for that one.

The old algorithm would lead to problems when the fragment durations
were too different for streams.

dbd6bde9d1 dashdemux: track segments in the demuxer

39924c60a1 dashdemux: remove buffering message emission from dashdemux 
dashdemux shouldn't emit the buffering message as that can pause
the pipeline. It has no proper knowledge of the downstream buffering
status so it can pause the pipeline when it isn't necessary. It should
have an internal buffer for downloading the streams ahead of playback,
but that shouldn't make it able to stop the pipeline for buffering.

A particular case in which this is bad is when a pad switch happens
(changing bitrates for example), the new pads dashdemux creates
will get linked to demuxers and new queues will be created,
these queues are initially empty and dashdemux will quickly
drain its buffers by pushing them to those queues. So it
would have no more buffers internally and would emit a
buffering message with a low ratio, causing the pipeline
to pause when it wouldn't be necessary.

2d85107299 dashdemux: correctly signal EOS on manifest end 
Put EOS on the streams queues after the last fragment from the
last period for each stream. This way we keep it serialized
with the buffers and it will work when streams have different
ending times

3a055ac2d1 dashdemux: Use the smallest queue value to define buffering state

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

f27bb684f7 dashdemux: Remove timing code that delays pushing of fragments

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.

375634f669 mpdparser/dashdemux: fixed get_width, get_height, get_audio_rate, get_num_audio_channels API functions 
the actual values now can be extracted also from the AdaptationSet element;
checking NULL structs for better robustness;

dd198bc86d mpdparser: fixed parsing of SegmentList syntax element, and eliminated Represention node list from Period node 
SegmentList nodes are allowed into Period, AdaptationSet or Representation nodes
and there is at most 1 element, so no need to keep a list;

Period nodes cannot have any Represention elements, as AdaptationSet nodes are mandatory;
this breaks compatibility with some legacy DASH test sequences.

43fea50c8a smoothstreaming: pass width, height, channels and rate as integer 
g_ascii_strtoull() returns a long long integer, but we need to
pass a normal int to gst_structure_set() for fields of G_TYPE_INT,
so cast appropriately.

GstBuffers. Replace gst_value_deserialize with a simpler, direct

e541ec7e63 mssdemux: replace unused parameter 
The buffer parameter wasn't being used, it was only to signal if
a buffer was downloaded and advance to the next fragment in the
manifest.

Replace the buffer with a boolean that has the same effect and is
safer

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.
