577dabf7b1 Use g_memdup2() where available and add fallback for older GLib versions 
g_memdup() is deprecated since GLib 2.68 and we want to avoid
deprecation warnings with recent versions of GLib.

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.
