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.

Iterator may need to be resynced, for instance if pads are released
during state change.
got_eos should be protected by the object lock of the element, not of
the pad, as is the case throughout the rest of the funnel code.

Writing a test for unscheduling the gst_clock_id_wait inside the
identity element, found an invalid read, caused by removing the clock-id
when calling _unschedule instead of letting the code calling _wait remove
the clock-id after being unscheduled.

Update test_seeking testcase to verify the render and render_list
virtual method handle buffers and buffer list containing multiple
memory blocks correctly.
https://bugzilla.gnome.org/show_bug.cgi?id=747223
GstFileSink implements the render_list virtual method to render
a list of buffers. Update the test_seeking test case to also
check the render_list method implementation.

This property avoids not linked error when all the pads are unlinked
or when there are no source pads. This is useful in dynamic pipelines
where it can happen that for a short time there are no pads at all or
all downstream pads are not linked yet.

3 new tests:
1) Tests that a stream that is empty (just an EOS event)
on inactive pad doesn't get through and tamper
with the active pad that still has data
2) Tests that a stream that is shorter than the active one
(pushes EOS earlier) doesn't has its EOS pushed
3) Tests that switching to an inactive stream that has received
EOS will make input-selector push EOS

Demultiplex a stream to multiple source pads based on the stream ids from the
stream-start events. This basically reverses the behaviour of funnel.

In this mode we accept previously set filter caps until
upstream renegotiates to something that is compatible
to the current filter caps.
This allows dynamic caps changes in the pipeline even
if there is a queue between any conversion element
and the capsfilter. Without this we would get not-negotiated
errors if timing is bad.

Make pipe socket non-blocking, so we don't
end up being blocked in a write on the pipe
while the src is eos and not reading data
any more, and thus we never unblock and never
notice that we're done. This would happen
quite reliably on the rpi.
When no data is coming from sinkpads and eos events
arrived at one of the sinkpad, funnel forwards the EOS
event to downstream. It forwards the EOS because lastsink pad
is NULL. Also the unit testcase of the funnel is not checking
the correct behavior as it should. The unit test case should
fail if one of the sink pad has already EOS present on it and
we are trying to push one more EOS.

From the test case:
/* This test creates a multiqueue with 2 streams. One receives
* a constant flow of buffers, the other only gets one buffer, and then
* new-segment events, and returns not-linked. The multiqueue should not fill.
*/
If one of the queues goes EOS and the other returns NOT_LINKED the stream
can be considerered EOS as a NOT_LINKED means that one of the branches has no
sink downstream that will block the EOS message posting.

The check itself is racy.
(CK_FORK=no GST_CHECK=test_output_order make elements/multiqueue.forever).
The problem is indeed the test and not the actual element behaviour.
The objects to push are being pulled out of the single internal queues in the
right order and at the right time...
But between:
* the moment the global multiqueue lock is released (which was used to detect
if we should pop and push downstream the next buffer)
* and the moment it is received by the source pad (which does the check)
=> another single queue (like the unlinked pad) might pop and push a buffer
downstream
What should we do ? Putting a bigger margin of error (say 5 buffers) doesn't
help, it'll eventually fail.
I can't see how we can detect this reliably.
