a941b4651c queue: Wake up the query function on errors from the loop function
Otherwise we might wait forever for serialized queries to be handled as the
loop function is stopped and as such we will never ever dequeue the query and
handle it.

38657bff51 queue: Do not hold GST_QUEUE_LOCK while posting ERROR messages
This might create deadlocks and we need to avoid holding element
specific lock while posting messages

For example a deadlock will happen if while posting the message,
someone connected on the bus (sync) tries to DOT the pipeline.

93d8679b00 queue: fix race when flush-stop event comes in whilst shutting down
Don't re-start the queue push task on the source pad when a
flush-stop event comes in and we're in the process of shutting
down, otherwise that task will never be stopped again.

When the element is set to READY state, the pads get de-activated.
The source pad gets deactivated before the queue's own activate_mode
function on the source pads gets called (which will stop the thread),
so checking whether the pad is active before re-starting the task on
receiving flush-stop should be fine. The problem would happen when the
flush-stop handler was called just after the queue's activate mode
function had stopped the task.

6a261b1fc2 queue: Post errors when receiving EOS after downstream returned an error
There might be no further data flow that would allow us to propagate the

6f042f13ae queue: Fix handling of serialized queries

09bb0c2cdb queue: remove query from queue if queue is flushing
When querying a queue that is flushing we end up adding
a query to the queuearray without taking a reference to
that query (because the normal functionality is to block
until that query is done and discarded from the queue).
This later causes problem if the query is unreffed outside
of the queue before we discard the queue. There is a check
to avoid unreffing any lingering query-objects, but since
the query has been deleted that check fails.

This commit depends on other fixes done to gst_queue_array_find()
and gst_queue_array_drop_element().

c257b19ead queue: don't fail in _sink_event for sticky events
Implement the same behaviour as gst_pad_push_event when pushing sticky events
fails, that is don't fail immediately but fail when data flow resumes and upstream
can aggregate properly.

This fixes segment seeks with decodebin and unlinked audio or video branches.

af2482b170 queue: add "flush-on-eos" property
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.

af73f3fc02 queue: Fix handling of min-threshold and serialized queries
Only consider the queue empty if the minimum thresholds
are not reached and data is at the queue head. Otherwise
we would block forever on serialized queries.

This also makes sending of serialized events, like caps, happen
faster and potentially improves negotiation performance.

Fixes bug #679458.
