During FLUSH_START the query needs to be unblocked already, otherwise
it can lead to deadlocks if the FLUSH_START is the result of something
done from the streaming thread of the srcpad (the queue will never be
emptied!).
Fixes some deadlocks during flushing.
And store queue items differently to not accidentially read
already unreffed queries when flushing. Queries are owned by
upstream and not us.
But do this only for events that are not dropped by flushing,
i.e. do it only for everything except SEGMENT and EOS.
Without this we might drop a CAPS event if flushing happens
at an unfortunate time and nobody is resending the CAPS event.

If a pad block was triggered from sending a sticky event downstream, it
could happen that the pad block is relinking pads, which then requires
to resend previous sticky events.
Previous patch was inforcing a complete ordering of the sticky events, while
in fact, only STREAM_START, CAPS and SEGMENT events need proper ordering.
See: https://bugzilla.gnome.org/show_bug.cgi?id=688188
In the case the source has no caps, caps must be sent before segment. This
fixes few unit tests that where failing due to the new misordering warning.

We can prevent buggy element from causing other elements to fail or crash
by sorting sticky event at insertion. In this case, we also warn as this
is not supposed to happen.

As long as the scripts' filenames are different, and the _gst_inspect
and _gst_launch functions are named differently, the completion scripts
for GStreamer 1.0 and 0.10 can be installed side-by-side in
/etc/bash_completion.d.
On my 0.10 branch† the completion script is renamed to
"gstreamer-completion-0.10" and the functions are renamed to
"_gst_inspect_0_10" and "_gst_launch_0_10". The remaining helper
functions should remain identical (the command-line interface to
gst-inspect hasn't changed, nor has the format of the gst-launch
pipeline), so it doesn't matter if the 1.0 script overrides the 0.10
script's definitions.
Note that I don't expect there to be another GStreamer 0.10 release, so
the 0.10 completion script will probably never be officially released;
but it is still worthwhile allowing both scripts to be installed
alongside each other, for those who install the 0.10 completion script
manually.
Fixes: #690515
