7f21226956 dashdemux: offset segment numbers by startNumber
For SegmentTemplate elements containing a startNumber attribute, the
`number' member of GstMediaSegments should be offset by the value of
startNumber; however, this is not currently the case. As a result, the
first URI(s) requested by the download loop will be wrong.

This commit ensures that segment numbers will be offset by startNumber
when one is present in a SegmentTemplate element.

19a45554bf dashdemux: remove incorrect timestamp scaling.
When using a SegmentTemplate element, the timestamps of the buffers
output by dashdemux are incorrect, causing problems downstream.

The reason is that GstMediaSegment start times are calculated (in
gst_mpdparser_get_chunk_by_index) by multiplying segment index by
segment duration and then scaling the result according the `timebase'
attribute from the MPD. However, the segment duration is already a
GstClockTime (i.e., it has already been scaled according to the timebase
from the MPD and converted to a nanosecond value), so multiplying it by
the segment index will give the correct timestamp without the need for
any further scaling.

1b1332cb6d mssdemux: use gst_data_queue_push_force for adding events to queue
This prevents locking on startup when a stream only has a single buffer
for one of the streams and mssdemux decides to push an EOS event right
after it.

2db211e243 dashdemux: use push_force when adding events to the dataqueue
This prevents deadlocks on startup on files that have only a very
large buffer for a stream and the queue is filled and will lock on
the eos event that is pushed after the buffer. As no buffers have yet
been pushed to other streams, the pipeline locks on preroll

ed16c9c560 hls: fix for assert failure when using encrypted HLS streams
When using an HLS encrypted stream, an assertion failure is thrown:
(gst-launch-1.0:31028): GLib-GObject-WARNING **: cannot register
existing type `GstFragment'

(gst-launch-1.0:31028): GLib-CRITICAL **: g_once_init_leave: assertion
`result != 0' failed

Eventually tracked this down to the call gst_fragment_new()
in function gst_hls_demux_decrypt_fragment.

The GstFragment class is defined in ext/hls/gstfragment.c and in
gst-libs/gst/uridownloader/gstfragment.c. Having two class definitions
with the same name causes the assert failure when trying to allocate
GstFragment. Deleting the version from hls and editing the
Makefile.am solves this assert failure.

5a5e66ec90 dashdemux: handle live playback resync
During a live stream it is possible for dashdemux to lag behind on a
slow connection or to rush ahead of the connection os too fast.

For the first case it is necessary to jump some segments ahead to be able to
continue playback as old segments are usually deleted from the server.

For the later, dashdemux should wait a little before attempting another
download do give time to the server to produce a new segment

b316d8a677 dashdemux: fix template based segment generation
When using a template based segment list, do not try to
contruct a finite segment list for the limits of the available periods.

We might not know when the period ends (for live streams) and we can
always create the segment on demand when requested by dashdemux,
avoiding use of some memory and cpu when re-creating this list.

a8a355108a dashdemux: use more appropriate data structures for parsing
Replaces the 2 likely larger lists with more appropriate structures
to improve performance.

Replaces S nodes GList for a GQueue, this reduces latency to startup
because of traversing the list just append an element.

Replaces the processed media segments GList for a GPtrArray as it is
constantly acessed by index during playback.

5ad2a2d161 dashdemux: Change first fragment selection for live streams
When dashdemux selects its first fragment, it always selects the
first fragment listed in the manifest. For on-demand content,
this is the correct behaviour. However for live content, this
behaviour is undesirable because the first fragment listed in the
manifest might be some considerable time behind "now".

The commit uses the host's idea of UTC and tries to find the
oldest fragment that contains samples for this time of day.

5920ee2777 dashdemux: Implement inheritance for certain MPD elements
According to the MPEG-DASH spec, certain elements (i.e.
SegmentBase, SegmentTemplate, and SegmentList) should inherit
attributes from the same elements in the containing AdaptationSet
or Period.

Updated the SegmentBase, SegmentTemplate, and SegmentList parsers
to properly inherit attributes from the corresponding elements in
AdaptationSet and/or Period.

Convert all xml attribute/content parsing functions to return a

implement the inheritance policies described in the spec

Also fixed several memory leak conditions when handling errors in
the xml attribute/content parsing functions.
