Ryan Lortie 799e0242ae improve thread safety in GDelayedSettingsBackend
- hold a lock while accessing the tree of delayed values
  - use weak reference counts with the owner object to avoid doing
    g_object_notify on a dead object
  - dispatch the "has-unapplied" notify to the proper main context
