Otherwise it can easily happen that the pad is destroyed before the
thread disappears, as happened sometimes in the test_pad_probe_block_add_remove
test where joining of the thread was done *after* the pad was unreffed
and destroyed.
Fixes https://gitlab.freedesktop.org/gstreamer/gstreamer/issues/339
Existing test for iterating/removing buffer meta data was insufficient
to detect linked list corruption when removing multiple items, and could
also suffer from such corruption in attempting to count remaining items.
Modified the one test and added several others to exercise multiple
scenarios.
Validates fix for issue #332.
We won't be able to do ASSERT_CRITICAL, but the main body of the tests
are still valid, and given we ship GStreamer with this configuration, it
is important to be able to run some tests against it.
Allows determining from downstream what the expected bitrate of a stream
may be which is useful in queue2 for setting time based limits when
upstream does not provide timing information.

A pointer to a hook in this list can easily not be unique, given both
the slice-allocator reusing memory, and the OS re-using freed blocks
in malloc.
By doing many repeated add and remove of probes, this becomes very easily
reproduced.
Instead use hook_id, which *is* unique for a added GHook.
If a segment has stop == -1, then gst_segment_to_running_time()
would refuse to calculate a running time for negative rates,
but gst_segment_do_seek() allows this scenario and uses a
valid duration for calculations.
Make the 2 functions consistent by using any configured duration
to calculate a running time too in that case.

Using a rate of 1.1 in the test is causing the test to
fail on 32-bit because ceil(1.1 * 10) can round to 12.
Instead use a rate 2.0 that can be expressed as floating
point number and doesn't trigger the problem.

Fixes for gst_segment_position_from_running_time_full() when
converting running_times that precede the segment start (or
stop in a negative rate segment)
The return value was incorrectly negated in those cases.
Add some more unit test checks for those cases, and especially
for segments with offsets.
Otherwise it's not guaranteed that buffers are actually on disk after
pushing them, and reading the file via g_file_get_contents() might not
include them yet.
This reverts commit 11e0f451eb.
When pushing a sticky event out of a pad with a pad probe or pad offset,
those should not be applied to the event that is actually stored in the
event but only in the event sent downstream. The pad probe and pad
offsets are conceptually *after* the pad, added by external code and
should not affect any internal state of pads/elements.
Also storing the modified event has the side-effect that a re-sent event
would arrive with any previous modifications done by the same pad probe
again inside that pad probe, and it would have to check if its
modifications are already applied or not.
For sink pads and generally for events arriving in a pad, some further
changes are still needed and those are tracked in
https://bugzilla.gnome.org/show_bug.cgi?id=765049
In addition, the commit also had a refcounting problem with events,
causing already destroyed events to be stored inside pads.
Previously gst_buffer_list_foreach() could modify (drop or replace)
buffers in non-writable lists, which could cause all kinds of problems
if other code also has a reference to the list and assumes that it stays
the same.

gst_buffer_list_new_sized(0) will cause an underflow in a calculation
which then makes it try to allocate huge amounts of memory, which
may lead to aborts.

In the case where the user sets a new padprobeinfo->data in a probe
where the data is a sticky event, the new sticky event should be automatically
sticked on the probed pad.

Remove unneeded reapplication of patterns. Besides being
superfluous (gst_debug_reset_threshold already applies
patterns) it was also wrong and didn't stop checking patterns
after the first match (broken in 67e9d139).
Also fix up unit test which checked for the wrong order.

The queue gets filled by the tail, so a query will always be the tail
object, not the head object. Also add a _peek_tail_struct() method to the
GstQueueArray to enable looking at the tail.
With unit test to prevent future regression.

Position queries with GST_FORMAT_TIME are supposed to return stream
time.
gst_base_sink_get_position() estimates the current stream time on its
own instead of using gst_segment_to_stream_time(), but the algorithm
used was not taking segment.offset into account, resulting in invalid
values when this field was set to a non-zero value.
https://bugzilla.gnome.org/show_bug.cgi?id=792434
Occasionally this test would fail, especially if the system is under load,
because the position query would pick up the last position from the
last buffer timestamp which has a lower timestamp than what we're
looking for. The sleep is long enough, however. It's unclear to me why
exactly this happens but there seems to be some kind of scheduling
issue going on as the streaming thread floods the sink with buffers.
Let's throttle the fakesrc to 100 buffers per second and make the sink
sync to the clock to restore some sanity. It should be totally sufficient
to test what we want to test, and seems to make things reliable here.
