0505bd76a1 gst-launch: Add support printing current position of pipeline
By default, gst-launch will print the current position of pipeline (with duration if available).
To disable it, use "--no-position" option.

be3c4d00cf event: Add new GST_EVENT_INSTANT_RATE_CHANGE and GST_SEEK_FLAGS_INSTANT_RATE_CHANGE
A seek with that flag set must be non-flushing, not change the playback
direction and start/stop position. A seek handler will then send the new
GST_EVENT_INSTANT_RATE_CHANGE event downstream for downstream elements
to immediately apply the new playback rate before the new in-band segment
event arrives.

0ca0a9d982 queue2: Use g_object_notify_by_pspec
`g_object_notify()` actually takes a global lock to look up the
`GParamSpec` that corresponds to the given property name. It's not a
huge performance hit, but it's easily avoidable by using the
`_by_pspec()` variant.

d25a88e3a1 tee: First deactivate the pad and then remove it when releasing pads
This reverts a96002bb28, which is not
necessary anymore. If we release the pad after removing it then none of
the deactivation code will actually be called because the pad has no
parent anymore, and we require a parent on the pad for deactivation to
happen.

This can then, among other things, cause a streaming thread to be still
stuck in a pad probe because the pad was never flushed, and waiting
there forever because now the pad will actually never be flushed anymore.

7f7da6a0d0 tee: Check for the removed pad flag also in the slow pushing path
If a pad is currently being released we don't want to forward the
FLUSHING flow return but instead consider it as NOT_LINKED. FLUSHING
would also cause upstream to be FLUSHING.

This part was missed in a3c4a3201a and
resulted in a different (and wrong) workaround in
a96002bb28.

enabled explicitly via -Dintrospection=enabled.

just fine this is crashing bindings and user-supplied log functions that
(rightfully) don't expect anything but GObjects.

a9e2776074 deviceprovider: set the bus to non-flushing before calling klass->start
Not posting DEVICE_ADDED messages while a device provider is being
started makes things awkward for applications, as they have to call
get_devices() after starting the monitor.

This requires redundant code on the application side, and as far as
I understand also could cause race conditions, when a device gets
added between the calls to gst_device_monitor_start() and
gst_device_monitor_get_devices(), causing the application to "see"
the same device twice.

89dfda56e3 base: GstBaseSrc/GstBaseSink::get_caps: add (nullable) to filter
The virtual method named `get_caps` in both `GstBaseSrc` and
`GstBaseSink` has a `filter` parameter which can be `NULL` (the
default implementation in GstBaseSrc already considers the case).
Before this commit, there was no gtk-doc annotation representing this
fact, which caused the corresponding entry in the GIR file to also
miss this fact.

This caused bugs in other places, such inducing the Vala compiler to
introduce a wrongly assert on `(filter != NULL)` in every
implementation of the `get_caps` method implemented in Vala.

4812c4087f Don't pass default GLib marshallers for signals
By passing NULL to `g_signal_new` instead of a marshaller, GLib will
actually internally optimize the signal (if the marshaller is available
in GLib itself) by also setting the valist marshaller. This makes the
signal emission a bit more performant than the regular marshalling,
which still needs to box into `GValue` and call libffi in case of a
generic marshaller.

Note that for custom marshallers, one would use
`g_signal_set_va_marshaller()` with the valist marshaller instead.

link that a pad has, e.g. to find the corresponding pad of a multiqueue.
Added a helper function that will return either a single internal link,
if there's no other, or NULL.

f8d70b475c miniobject: free qdata array when the last qdata is removed
In cases with many long-lived buffers that have qdata only very
briefly, the memory overhead of keeping an array of 16 GstQData
structs for each buffer can be significant. We free the array when
the last qdata is removed, like it was done in 1.14.

no other known side effect in that test.

a4d5c95638 utils: Avoid memory merge in gst_util_dump_buffer()
For buffers with multiple memory chunks, gst_buffer_map() has the side
effect of merging the memory chunks into one contiguous
chunk. Since gst_util_dump_mem() used gst_buffer_map() the internals
of the buffer could actually change as a result of printing it.

For the case of a buffer containing several memory chunks,
gst_memory_map() is now used to obtain the memory address and each
memory chunk is dumped separately preceded by a header line. The
behaviour for a buffer containing a single memory chunk is left unchanged.

74797e962f aggregator: Always handle serialized events/queries directly before waiting
Otherwise it can happen that we start waiting for another pad, while one
pad already has events that can be handled and potentially also a buffer
that can be handled. That buffer would then however not be accessible by
the subclass from GstAggregator::get_next_time() as there would be the
events in front of it, which doesn't allow the subclass then to
calculate the next time based on already available buffers.

As a side-effect this also allows removing the duplicated event handling
code in the aggregate function as we'll always report pads as not ready
when there is a serialized event or query at the top of at least one
pad's queue.
