.. when computing the high id.
After a flush for instance, sq->srcresult is reset to OK,
yet it doesn't make sense to pick a non-existing position
id as the high id when a queue doesn't contain any items
in that situation either.
It is in any case completely OK to let the not-linked stream
get consumed without throttling at this stage, as any
first packet arriving on other single queues will get assigned
a higher position id.

Use gap events to update the next_time of a queue the same
as buffers or segment events. Fixes problems where a group
consisting only of sparse streams primarily driven by
gap events would stall with a full multiqueue because
unlinked streams in the group were not being woken to
push data.

When the probe returns GST_PAD_PROBE_REMOVE and gets called concurrently
from the streaming thread while we're in the callback here, the hook has
already been destroyed by the time we've reacquired the object lock.
Consequently, cleanup_hook gets passed an invalid pointer.
Keep another reference to the hook alive to avoid this situation.

This new tracer will list loaded elements and plugins. This should
make it easier to generate minimal builds of GStreamer.
This also traces other features such as typefind functions, device
providers and dynamic types.
The format of the output of gst-stats should match the parameters
expected by the meson based gst-build system.

We shouldn't fail to load plugins just because we don't
recognise the license string. It's not our job to validate
licenses, and the license list is outdated and ambiguous
anyway.
Also add MPL-2.0 to the list, and fix some defunct license
URLs in the code comments.
Get rid of the hard-coded skip index, doesn't really buy us
much versus just skipping with a few strlens, and is harder
to maintain.

Default timer precision of Windows is dependent on system, but
usually it's known to be about 15ms in worst case.
That's not an enough precision for multimedia application.
Enable high-resolution clock in gst-launch to demonstrate
the usage of Windows high-precision clock for application developers.

Normally uri is get from user input and invalid user input should not
be treated as critical error. Moved gst_uri_is_valid outside of
g_return_val_if_fail.
NULL uri is checked inside of gst_uri_is_valid and is correctly
treated as critical error, removed unneeded checks of NULL uri outside
of gst_uri_is_valid function.

When getting backtraces, we were always creating a new Dwfl context and then
discarding it. The problem with that is that it resulted in having to re-scan a
lot of information for every single backtrace.
In order to fix that issue, use a global on-demand Dwfl context and use it with
a lock.
Furthermore, we were scanning the mappings of the
process (dwfl_linux_proc_report) for *every single step* in the backtrace, and
that function is horrendously expensive (does sscanf on /proc/PID/maps
...). While there is a possibility that new mappings might be available (new
plugins being loaded for example), we can limit ourselves to just do it once per
backtrace.
These two modifications speed up the elements_leaks unit test (which traces all
pads with full backtraces) by a factor of 6.

Usually the latency message is only posted whenever latency of an
element changes but that might be too early as the sinks might not be
able to query the latency at that point yet.
Similarly adding a new sink should cause latency reconfiguration once
that new sink is able to report its latency.
This fixes latency configuration in pipelines where webrtcbin is the
only "sink", i.e. it is used in a sendonly session. Before, the latency
would always be configured to 0.

If a property is supplied to gst-launch-1.0 to set on a property that
implements GstChildProxy, it would always accept any property name
and try to set it later. This means that (for example) decodebin
will accept and not complain about property names that can never exist like:
gst-launch-1.0 videotestsrc ! decodebin NON-EXISTING_PROPERTY=adsfdasf ! fakesink
Instead, only try to do deferred property setting for property names
that contain the :: separator that indicates it's a setting on a child
that might appear later.

This allows us to cover the case where we're on some unknown system that
doesn't have a known native precision monotonic time source. Sadly this
reintroduces some of the complexity removed in previous commits.

The gst_system_clock_get_internal_time and
gst_system_clock_get_resolution functions had some nested defined checks
making this code somewhat harder to reason about and much harder to
change. The logical meaning of the checks has changed but the actual
code coming out of the pre-processor should not have changed
significantly. The main logical change was flattening the checks for
existence of posix timing functionality, from what I can tell these
functions aren't available on Windows where they were trying to be
included. I have checked the Linux and macOS output and they are
functionally unchanged.

Most of these are only of historical interest, and for that it's
fine if they're maintained in the git history. They're confusing
for anyone stumbling across them expecting documentation relating
to current versions of GStreamer.
