[BRIDGE]: netlink interface for link management

Browse Source 
Add basic netlink support to the Ethernet bridge. Including:
 * dump interfaces in bridges
 * monitor link status changes
 * change state of bridge port

For some demo programs see:

These are to allow building a daemon that does alternative
implementations of Spanning Tree Protocol.
