API: Refactor GstController into the core controller which can take
a GstControlSource for providing actual values for timestamps.
Implement a interpolation control source and use this for backward
compatibility, deprecate a bunch of functions that are now handled
by GstControlSource or GstInterpolationControlSource.
Make it possible to disable the controller completely or only for
specific properties. Fixes#450711.

* tests/check/pipelines/simple-launch-lines.c
(test_state_change_returns): Enable pull-mode tests now that
basesink has been fixed.
* libs/gst/base/gstbasesink.c (gst_base_sink_needs_preroll):
Changed from gst_base_sink_is_prerolled, reversing the sense of
the return value. Returns FALSE also if the sink is in pull mode,
in which case it needs no preroll.
(gst_base_sink_query, gst_base_sink_change_state): Update for
needs_preroll change.
(gst_base_sink_change_state): Add a case for READY_TO_PAUSED after
chaining up, in which we return SUCCESS directly if we activated
in pull mode instead of ASYNC. Involves countering an async_start
message sent before chaining up; not sure if this is correct, in
an ideal world we only send async-start when activating in push
mode.

(gst_single_queue_new):
Keep track of time in the queue by measuring the difference between
running_time on input and output. This gives more accurate results and
can compensate for segments correctly.
Make a queue by default only 5 buffers deep. We will now increase the
buffer size depending on the filledness of the other queues.
Factor out commong flush code.
Make sure we don't add additional refcounts to buffers when we can avoid
it.
Propagate GstFlowReturn differently.
Use GSlice for intermediate GstMultiQueueItems.
Keep track of EOS.
Resize queues on over and underruns based on filled level of other
queues.
When checking if the queue is filled, prefer to measure in time if we
can and fall back to bytes when no time is known.

Ugly 'fix' for the controller unit test on the p5 bot: in
fail_unless_equals_float() check whether the values are 'almost
equal' by allowing a small absolute error, which should be good
enough for our use cases (normal numbers and values close to 0).
Proper fixage left to floating point arithmetic aficionados.

of "return (foo)".

Fix multiqueue leaking buffers and events when downstream or the
queue are flushing. Make refcounting assumptions explicit and
document them (shouldn't break existing code that uses it other than
maybe leak miniobjects, but that already happens anyway). Add unit
test for the most common flushing case. Fixes#423700.
Original commit message from CVS:

* libs/gst/controller/gstinterpolation.c:
Factor out the 'set' logic into gst_controller_set_unlocked for the
gst_controller_set and gst_controller_set_from_list functions.
To make life of the interpolators easier always add a control point
at timestamp zero with the default value.
In the linear interpolator make things more obvious by better variable
naming (slope).
Implement cubic interpolation mode (by using a natural cubic spline)
and map the quadratic interpolation mode to this too (as quadratic
doesn't make much sense, see discussion on the list).
* tests/check/libs/controller.c: (GST_START_TEST),
(gst_controller_suite):
Add unit test for the cubic interpolation mode and check everywhere
if the interpolation mode could be set as expected.

Original commit message from CVS:
* libs/gst/controller/gstcontroller.c:
(gst_controller_get_value_array):
* libs/gst/controller/gstcontroller.h:
Clarify the docs of gst_controller_get_value_array(): The array where
the values should be written to must be allocated as there seems to be
no way to get the size of a random GType. This doesn't change any
behaviour. Also fix some typos all over the place and remove an unused,
commented function that is not necessary as g_object_set() could be
used instead.
* tests/check/libs/controller.c: (GST_START_TEST),
(gst_controller_suite):
Add unit test for gst_controller_get_value_array().

API: gst_controller_suggest_next_sync(), gst_object_suggest_next_sync()
Add API that provides sync suggestion timestamps for elements that
call gst_object_sync_values() from which those elements can subdivide
their processing loop to get the best results for the controlled
properties. For now it just suggests last_sync + control_rate as
new timestamp but this will be improved in the future.
While doing that change the control-rate property to a GstClockTime
from guint and change it's meaning from samples to nanoseconds as
the GstController doesn't know anything about sampling rate. Strictly
speaking this breaks ABI but as the control-rate property didn't do
anything in the past and as such couldn't be used this should be no
problem.

values next to each control point. From the outside everything is
still a GstControlPoint so we don't loose binary compatibility.
Also fixup all the GValue handling to not leak GValues or list nodes.

Original commit message from CVS:
* libs/gst/base/gstbasetransform.c: (gst_base_transform_activate):
Make sure streaming has finished before calling the ::stop() vfunc,
since that vfunc might clear state which is being used in the
streaming thread. This fixes a race that caused crashes in
audioresample when shutting down a pipeline (#420106).

Allow basesrc derived classes to execute seeks in other formats
by providing a prepare_seek_segment vmethod. Sub-classes can choose
to prepare the GstSegment in any format that their perform_seek method

old behaviour of attempting to convert the seek offsets to the
configured native format.
