ui/console-vc: fire ADDED/REMOVED notifications

Browse Source 
Fire CONSOLE_ADDED when the chardev is opened.

Fire CONSOLE_REMOVED in char_vc_finalize() before dropping the console
reference, so the console is still in a valid state when listeners
handle the event. Also fixes a console object leak by adding the
missing object_unref().
