audiomixer: rework event handling to avoid race conditionsicefish_8.99.5icefish/8.99.58.99.5
Previously there was a race condition that would happen when
audiomixer was the first client to connect to pipewire.
It would get a session first and then a default endpoint id
from the session, but at the time the default endpoint id
would be known, the WpProxyEndpoints would still not be ready.
This would cause the populate_controls() algorithm to end up
with no controls and the binding would therefore report that
no controls were exposed.
Now we also handle objects-changed from the endpoints object manager.
This is an additional trigger, so that when we end up in the
situation described above, the objects-changed from the endpoints om
will trigger the controls to be exposed eventually.
In order to avoid signalling control changes all the time,
there are now some checks to change controls only under
certain conditions.
