While we can fixe the upstream latency using the min-upstream-latency, we
are now forced to use queues (hence more thread) in order to store the pending
data whenever we have an upstream source that has lower latency.
This fixes the issue by allowing to buffer the fixed upstream latency. This is
particularly handy on single core systems were having too many threads can
cause serious performance issues.

Subsequent lookups in the hashtable are probably better done
on memory we're confident is allocated to us :)
It was easy to trigger invalid reads by calling gst_meta_register
with dynamically allocated memory, freeing that memory, then
calling gst_meta_get_info()

... and update meson file so that enable it only using required headers.
"dependency(...)" is unlikely successful for Windows SDK libraries
since it doesn't ship pkg-config file. So it needs to be changed
to "find_library()" to link corresponding .lib file. That would
result to most MSVC build system will link dbghelp.dll. However,
one drawback of the change is that gstreamer-1.0.dll will mandate
dbghelp.dll although it should be optional. So g_module_open() way
can be the most safe way in this case.

When going to PLAYING we will now have a clock and can stop waiting on
the condition variable and instead start waiting on the clock if
necessary for the current configuration.
In the other direction when going to PAUSED the clock might have
disappeared and we might need to wait on the condition variable again
instead.

On the first buffer the base class would update the segment position
based on the start-time-selection. If the subclass provides its own
segment this will caused unexpected behaviour and override segment
information that was explicitly set by the subclass.

See https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/issues/771
for context.
This exposes new API that subclasses must call from their
aggregate() implementation to signal that they have selected
the next samples they will aggregate: gst_aggregator_selected_samples()
GstAggregator will emit a new signal there, `samples-selected`,
handlers can then look up samples per pad with the newly-added
gst_aggregator_peek_next_sample.
In addition, a new FIXME is logged when subclasses haven't actually
called `selected_samples` from their aggregate() implementation.

Make g-ir-scanner skip all those check macros that are
not useful for or usable from bindings.

It's been around for more than 4 years and people have built
lots of stuff on top of it, doesn't really make sense to keep
it marked as unstable. We're unlikely to change it now, and
we can always deprecate it and make a new one if needed.
This stabilises the following API:
- gst_tracer_register()
- gst_tracing_get_active_tracers()
- gst_tracing_register_hook()
- gst_tracer_record_new()
- gst_tracer_record_log()
Might also help a bit with #424
