31e6d766ff gst: Delay creation of threadpools
Since glib 2.64, gthreadpool will start waiting on a GCond immediately upon
creation. This can cause issues if we fork *before* actually using the
threadpool since we will then be signalling that GCond ... from another process
and that will never work.

Instead, delay creationg of thread pools until the very first time we need
them. This introduces a minor (un-noticeable) delay when needing a new thread
but fixes the issues for all users of GSTreamer that will call gst_init, then
fork and actually start pipelines.

See https://gitlab.gnome.org/GNOME/glib/-/issues/2131 for more context.

e272ae281f task: Introduce gst_task_resume() API
This new API allow resuming a task if it was paused, while leaving it to
stopped stated if it was stopped or not started yet. This new API can be
useful for callback driver workflow, where you basically want to pause and
resume the task when buffers are notified while avoiding the race with a
gst_task_stop() coming from another thread.

daa98fc02a gst: Don't ref_sink() GstObject subclasses in instance_init/constructor
This is something bindings can't handle and it causes leaks. Instead
move the ref_sink() to the explicit, new() constructors.

This means that abstract classes, and anything that can have subclasses,
will have to do ref_sink() in their new() function now. Specifically
this affects GstClock and GstControlSource.

519d64881f Don't use deprecated g_object_newv()
Use g_object_new() instead which nowadays has a shortcut for the
no-properties check. It still does an extra GType check in the
function guard, but there's a pending patch to remove that
and it's hardly going to be a performance issue in practice,
even less so on a system that's compiled without run-time checks.

Alternative would be to move to the new g_object_new_properties()
with a fallback define for older glib versions, but it makes the
code look more unwieldy and doesn't seem worth it.

Fixes deprecation warnings when building against newer GLib versions.

40727d9c83 element: clean up thread pool from gst_task_cleanup_all()
This ensures that all async operations (started from gst_element_call_async())
have been completed and so there is no extra thread running.

Fix races when checking for leaks on unit tests as some of those
operations were still running when the leaks tracer was checking for
leaked objects.

6c079367f1 task: Fix pause/stop race condition
If a task thread is calling pause on it self and the
controlling/"main" thread stops the task, it could end in a race
where gst_task_func loops and then checks for paused after the
controlling thread just changed the task state to stopped.
Hence the task would actually call func again even though it was
both paused and stopped.
