Disable automatic port configuration in acp and move the logic
to the session manager.
Implement initial port selection and restore on profile activation.
Implement route switch when unavailable
Implement port settings save.
Keep track of active profile in default-routes so that we can restore
the prefered routes later.
Keep track of all active routes in an array. There can be more than
one active route per direction.
New routes will get their volume restored. Route changes will be saved.
Follow the active input/output routes. If the route changes, restore
the previously saved settings. If only the properties change, save
them to be restored later.
Fixes#402
Save settings as jason and use a small json compatible tokenizer to
load settings instead of our own less flexible format.
Save settings with a prefix and filter out entries without prefix
Listen for changes in restore.stream metadata and update properties.
