5f4723d842 tests: Add more tests for gsturi
Add tests that exercise unescaping of userinfo and fragments.

Also convert to a modular macro-based definition so that we can reuse
the list of tests in the next commit.

d74efc1aed aggregator: expose sample selection API
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.

e4f7cdb0df tracer: declare GstTracer API stable
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

3cfda6d6eb gstelementfactory: Fix missing features in case a feature moves to another filename
In case a plugin filename was renamed with the plugin being in the registry cache
the features were not loaded after the rename:

1) Cache of old/gone filename was loaded, features added
2) New filename was loaded, features where not added because
   they were already found in the registry.
3) In the end stale cache entries for files which are no longer there
   are removed, including the wanted features.
4) The cache gets updated without the features.

Fix this by also checking at (2) that the found feature is from the loaded plugin
and not from some stale cache entry.

This affected directsoundsink where libgstdirectsoundsink.dll was renamed
to libgstdirectsound.dll, losing the directsoundsink element in the process.

65e89d45b8 hooks: add opt-in cache update hook
CI now checks that plugin caches are up to date, for example
when adding a new property to an element.

This is something pretty easy to forget, and it can be checked
in a pre-commit hook provided the cache generator generates no
unnecessart diff on the developer's machine. This is now the
case for me in core, -base and -good, and eventually all the
repositories should behave appropriately, at least on my
development machine.

The new check in the pre-commit hook is only performed when
the user is in the development environment (it checks
$MESON_BUILD_ROOT to determine that), and when the developer
has opted-in by setting `GST_CACHE_HOOK=enabled`. That is
because the hook will actually rebuild the cache with ninja,
and modify it in the source directory, that's not a behaviour
we want to enable by default.

1206a60bac bus: clear bus->priv->signal_watch immediately when the source is removed
There is a race-condition that can trigger the assertion in
gst_bus_add_signal_watch_full():

If gst_bus_add_signal_watch_full() is called immediately after
gst_bus_remove_signal_watch() then bus->priv->signal_watch may still be set
because gst_bus_source_dispose() or gst_bus_source_finalize() was not yet
called.
This happens if the corresponding GMainContext has the source queued for
dispatch. In this case, the following dispatch will only unref and delete
the signal_watch because it was already destroyed. Any pending messages
will remain until a new watch is installed.

So bus->priv->signal_watch can be cleared immediately when the watch is
removed. This avoid the race condition.
