3dd0888d1e playbin3: Remove source property
And instead use the "setup-source" signal. This opens the way to deal
with more than one 'source' for a given playlist entry

35a8d42724 parsebin: Don't let thread run after unref
We have a dedicated one-shot thread to handle cleanup of old groups.

While this is a good idea. It's an even better idea to make sure
that thread is *completed* before the parsebin element to which
it is related isn't freed/gone.

* There can only be one cleanup thread happening at any point in time.
  If there is already one, we wait for the previous one to finish.
* When shutting down (NULL=>READY) make sure the thread is finished

d53ccfd8e5 parsebin: Check for shutdown before exposing pads

92e8876844 parsebin: Emit 'drained' only for the top-level chain
Instead of emitting 'drained' whenever every single chain is drained
(which would result in plenty of signal emission, and would also
occur when switching groups), only emit it when the top-level chain
is drained.

Furthermore, mark unknown (and therefore unexposed) pads as drained
since we'll never get EOS on them.

895d884701 oggdemux: Solidify gst_ogg_demux_loop_push() some more
There were still some races going on where seeking events wouldn't
be properly intercepted/executed by this thread.

* Instead of always waiting for the GCond to be emitted, first just
  check if there is an event available
* Take ownership of the event *while* the lock is taken and not
  after releasing/reacquiring it
* Finally acquire lock at the very top and release it at the end
  to make it a bit more streamlined

This removes the remaining issues with seeks not being executed

9f678bb27f oggdemux: Don't double-unlock

gst_ogg_demux_seek_back_after_push_duration_check_unlock()

c86df789ed oggdemux: Drop data before new segment
When calculating duration in push-mode we seek to a certain position
and discard any data until we get data from that requested position.

The problem is that basing ourselves solely on offset to determine
whether we reached the target offset is wrong since the source might
be fast enough  to send us that target position *before* it processed
the requested seek.

This would end up in a situation where:
* We think we're done with duration estimate
* We fire a seek back to "0" in the loop thread
* We resume normal processing
* ... except that we're still getting data from too far ahead which
  we decide to process.
* And we start doing totally wrong granule/time/duration calculation
  and pushing wrong data.

Instead of this confusion, wait until we receive data from the requested
seek. We do that by using the fact that the seqnum in
seek_event_drop_til will be non-zero until the SEGMENT corresponding
to the requested SEEK has been received.

Bonus: makes startup slightly faster

0a49b93ade oggdemux: Wait for push loop to be started
Code using the push_loop_thread (using for sending seeks) assumes
that the thread was properly started, except that this isn't always
true and the thread might not have completely started.

Instead wait for the thread to properly start before doing anything
else.

2ec51ef998 playbin: Don't ref_sink() the sinks twice
Since we're already sunk floating reference, we shouldn't call ref_sink

9a8cb29970 discoverer: Avoid race of adding elements while stopping
This would result in a lot of warnings regarding elements not being
in NULL state when removed, or even leaked elements.

Instead make sure we take the lock and check whether we are processing
or not before allocating or adding anything to the pipeline

91179622eb sdpmessage: add_attribute accepts NULL value
The attribute can be defined without value regardless session-level
or media-level.
Although `gst_sdp_message_insert_attribute` can be used to set NULL,
it would be easier if `gst_sdp_message_add_attribute` accepts NULL.

f448cecceb decodebin2: Recheck shutdown behaviour in error case
If we can expose the main chain, recheck whether we are shutting
down or not.

decodebin2 might have been set to READY/NULL during the attempt
to expose, which would cause it to fail ... but it is not a fatal
issue.

initialized yet.

Instead of that, use a default blank/empty first entry.
