syrinx b5c537984b Add two new flags to if_bridge(4) indicating whether the edge flag
of the bridge port and path cost have been administratively set or
calculated automatically by RSTP.

Make sure to transition from non-edge to edge when the port goes down
and the edge flag was manually set before.
This is needed to comply with the condition
	((!portEnabled && AdminEdge) || ....)
in the Bridge Detection State Machine (IEE802.1D-2004, p. 171).
