Use GST_PAD_PROBE_PASS to pass through all events other than EOS instead of
blocking on the first non-EOS event forever. Also fix a typo in a comment in
that function.
Thanks to David Jaggard for reporting this on the mailing list.
'gst_element_post_message' takes the ownership of the message, so it
shall unref it when there is no post_message implementation. Otherwise
message is leaked.

This lock seems to exist only to prevent elements from changing states while
events are being processed. However events are going to be processed
nonetheless in those elements if sent directly via pads, so protection must
already be implemented inside the elements for event handling if it is needed.
As such having the lock here is not very useful and is actually causing
various deadlocks in different situations as described in
https://bugzilla.gnome.org/show_bug.cgi?id=744040
segment.position is meant for internal usage only, but the various
GST_EVENT_SEGMENT creationg/parsing functions won't clear that field.
Use the appropriate segment boundary as an initial value instead
Otherwise each bin might have a different latency in the end, causing
synchronization problems.
The bin will still first handle latency internally as before, but gives the
overall pipeline the opportunity to update the latency of the whole pipeline
afterwards.

Watching videos with variant bitrate is common to have delta
more than 10 kbps, resulting in tag list spam.
Instead of relying on fixed 10 kpbs delta, it is better to
calculale the difference in percentage and update tag list
only when bitrate changes more than 2%.

The pad could be activated but flushing because of a FLUSH_START event. That's
not what we're looking for here, we want to check for activated pads.

Changing states up and down while buffers are being pushed is not
a valid use case. If a pad is deactivated and reactivated during
a buffer push it is racy with the check of pushed sticky events
and the actual chainfunction call. As it might call the chain
without noticing the peer pad lost its previous sticky events.

My previous fix for #758029 wasn't quite right and simply made the race rarer.
Some of the files are installed by install-exec and others by install-exec, so
the hooks need to be split too.

When synchronizing the output by time, there are some use-cases (like
allowing gapless playback downstream) where we want the unlinked streams
to stay slightly behind the linked streams.
The "unlinked-cache-time" property allows the user to specify by how
much time the unlinked streams should wait before pushing again.
