node: add master priority

Browse source 
Change node.priority to priority.session to indicate that this
is the priority that the session manager uses to select the node.

Add another priority.master that the core uses to select a master
driver. Keep the driver nodes sorted by master priority.

Let jack always prefer to connect to the master driver nodes.
