Remove gst_init() from a few tests. Use _OBJECT variants in logging. Remove
arbitrary extra blank lines. Make push_event() more like push_buffer() - set
the event to NULL and add cleanup to _chain_data_clear().
Using two (or more) probes on the same pad where one of the probe
returns HANDLED or DROP is tricky since the other probes might
not be called.
Instead use regular probes and a proper pad (the sinkpad already existed,
it only required to be activated and have a dummy chain function for
the events/buffers to be received/handled properly)
Failure by this commit 2dfa548f36, which is
to append hooks instead of prepend.
Because of this change, aggretated_cb is not called and leads to failure.
And correct to check flush stop value instead of flush start value

When this is TRUE, we really have to produce output. This happens
in live mixing mode when we have to output something for the current
time, no matter if we have enough input or not.
When registering categories after gst_init() we would re-check *all*
categories against the existing GST_DEBUG patterns again, whereas
it's enough to just check the new category. Moreover, we would parse
the GST_DEBUG pattern string again and re-add that to the existing
pattern list for every newly-registered debug category, and then
check that against all categories of course. This made registering
categories after gst_init() very very slow.
Checking that the pad is in the correct mode before the parent is
checked makes the call always succeed if the mode is ok.
This fixes a race with ghostpad where gst_pad_activate_mode() could
trigger a g_critical() if the ghostpad is unparented while the
proxypad is deactivating, for instance if the ghostpad is released.
More specifically, gst_ghost_pad_internal_activate_push_default()'s
call to gst_pad_activate_mode() would fail if ghostpad doesn't have a
parent. With this patch it will return true of mode is already
correct.
An object that can be waited on and asked for asynchronous values.
In much the same way as promise/futures in js/java/etc
A callback can be installed for when the promise changes state.

Add convenience API that iterates over all pads, sink pads or
source pads and makes sure that the foreach function is called
exactly once for each pad.
This is a KISS implementation. It doesn't use GstIterator and
doesn't try to do clever things like resync if pads are added
or removed while the function is executing. We can still do that
in future if we think it's needed, but in practice it will
likely make absolutely no difference whatsoever, since these
things will have to be handled properly elsewhere by the element
anyway if they're important.
After all, it's always possible that a pad is added or removed
just after the iterator finishes iterating, but before the
function returns.
This is also a replacement for gst_aggregator_iterate_sink_pads().

Boy scout rule. Make is a little less painful to debug the tests by using
fail_unless_equals_{uint64,int64,float} where appropriate. Ideally the large
tests would be splitted to avoid guessing data dependencies.
For linked elements, the resulting gst_bin_iterate_sorted() will
properly return elements from sink to sources.
If we have some elements that are not linked, we *still* want to
ensure that we return:
* In priority any sinks
* Last of all any sources
* And in between any element which is neither source nor sink
For this to work, when looking for the next candidate element,
not only check the degree order, but if there are two candidates
with the same degree order, prefer the non-source one.
Amongst other things, this fixes the case where we activating a
bin containing unlinked sources and other elements. Without this
we could end up activating sources (which might start adding pads
to be linked) before other (to which those new source element pads
might be linked) are not activated

The real use case is when downstream didn't set a pool or
allocation params, in which case we expect the tee to not
create a pool or param from thin air. Dowstream setting
an pool with size=0 was in fact testing a downstream element
bug. The fact we handle that is accidental.
If the aggregated size is 0 and we create a pool, the pool would provide
buffers with no memory assigned. Handle that case and skip the pool.
This was the behaviour before cf803ea9f4.
Add a test for this scenario.

In the unit test refactoring, the unlinked pad required to test
the different behaviour induced by "allow-not-linked" property
was removed.
Commit e364d7944e
Move all the code for this test in the proper function, and re-add
the missing unlinked pad. This makes the test useful again.
Split the large allocation_query test into seperate tests. Add a setup helper
to reduce code duplication. Fix the original test that used fail_unless instead
of ck_assert_int_eq and had it accidentially working.
Need to pass -DGST_DISABLE_DEPRECATED to avoid warnings when
testing deprecated API such as gst_uri_construct().
Also remove #ifndef GST_DISABLE_DEPRECATED guard from header
file, we don't use those any more for functions, the
GST_DEPRECATED_FOR macro is enough.
