3f83ca9c43 multiqueue: do not post messages holding the lock
It might cause deadlocks to post messages while holding the multiqueue
lock. To avoid this a new boolean flag is set whenever a new buffering percent
is found. The message is posted after the lock can be released.

To make sure the buffering messages are posted in the right order, messages
are posted holding another lock. This prevents 2 threads trying to post
messages at the same time.

09982c3c13 dataqueue/queuearray: Make public API again
These are actually used outside of coreelements nowadays.
Also hide lots of internals and add padding and documentation.

434e7042d8 base: make GstDataQueue private API for multiqueue
There's no code that uses it other than multiqueue, so make it private
to multiqueue for now. That way we can also do optimisations that
require API/ABI breaks. If anyone ever wants to use it, we can still
make it public again.

383cac91b1 multiqueue: Increment unique item counter with atomic operations
Before it was only protected by the stream lock but every pad
has its own stream lock, making the protection rather useless.

99dd9830a9 multiqueue: add buffering support
Add support for buffering mode where we post BUFFERING messages based on the
level of the queues. It currently operates on the first queue that goes over or
under the high/low thresholds.

b95cc5031b multiqueue: avoid lock for taking the counter
The counter for incomming data is already protected with the STREAM_LOCK so we
don't need to add another lock around it.

afebd394fa plugins/elements/gstmultiqueue.*: Take the multiqueue lock when updating the fill level so we don't get confused.
Original commit message from CVS:
* plugins/elements/gstmultiqueue.c: (gst_multi_queue_init),
(gst_single_queue_flush), (apply_segment), (apply_buffer),
(gst_single_queue_push_one), (gst_multi_queue_loop),
(gst_multi_queue_sink_activate_push), (gst_multi_queue_sink_event),
(gst_multi_queue_src_activate_push), (wake_up_next_non_linked),
(compute_high_id), (gst_single_queue_new):
* plugins/elements/gstmultiqueue.h:
Take the multiqueue lock when updating the fill level so we don't get
confused.
After applying a buffer or event on the src pad segment, make sure to
call gst_data_queue_limits_changed() to get the data queue to unblock
and check the filled state again.
Rework the not-linked pad handling so the logic is that not-linked
pads can push as fast as they like, but only so they never get
ahead of any linked pads.
* tests/check/elements/multiqueue.c: (mq_sinkpad_to_srcpad),
(mq_dummypad_getcaps), (mq_dummypad_chain), (mq_dummypad_event),
(run_output_order_test), (GST_START_TEST), (multiqueue_suite):
Add a test to check that not-linked pads always stay behind
linked pads.
