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!).
In flush-on-eos=true mode any data remaining in the queue is
discarded when an EOS event is received, and the EOS passed
downstream as soon as possible (instead of waiting for all
buffers in the queue to get processed by downstream first).
May or may not be useful in capture/encoding scenarios.

When dropping buffers in leaky modes, mark next buffers we sent as
DISCONT.

When downstream returns UNEXPECTED from pushing a buffer, don't try to
push more buffers but allow pushing of EOS and NEWSEGMENT.
Add some more debug info here and there. Fixes#476514.

Refactor an cleanup queue a bit.
Do better time level calculations that also work when the srcpad is not
yet running.
Remove some unneeded debug lines.

Added testcase for time level measurement.
Try to make some stuff more racefree.

Be smarter when calculating the current amount of data in the queue by
measuring the difference between start and end timestamps (in running
time) inside the queue. Fixes#432876.
API: GstQueue::pushing to notify elements that we are pushing data again
since the running signal is rather broken for this purpose.

* plugins/elements/gstqueue.c: (gst_queue_init),
(gst_queue_locked_flush), (gst_queue_handle_sink_event),
(gst_queue_set_property):
* plugins/elements/gstqueue.h:
In queue, when EOS is received, if minimum threshold > max_size -
current_level, there is chance that queue blocks forever in conditional item
del wait. This is because the queue is not emptied completely due to minimum
threshold.
Here is another approach. Instead of setting cur_levels to max in EOS, just
zero all minimum threshold levels. This should make sure that queue gives out
all data. When going to READY (stop) state, just reset the original minimum
threshold levels.
Fixes#336336.

function.

Original commit message from CVS:
This is either a rewrite or a large bugfix to the queue element, whatever
you prefer to call it.
* upstream event forwarding now works. This should fix Julien's issues.
* this queue allows setting a min. treshold size and a max. limit size
in bytes, buffers and time before the queue allows the next element
to pull data or the previous element to push data into it. This is
very interesting for network-related buffering. Also includes signals
et all for the end user application.
* Events are no longer part of the queue's "size", they're essentially
seen as "void data". they have no size or time associated with them
anyway, so this shouldn't really sound weird.

Add patch for better buffering (especially useful for network streaming), see #108268 - kudos go to janzen@pixelmetrix.com
