Andrew Thompson 55ba40bfe2 Add rc.d/bridge which is invoked when a new interface arrives and can
automaticly add it to an Ethernet bridge. This is intended for applications
such as qemu, vmware, openvpn, ... which open tap interfaces and need them
bridged with the hosts network adapter, the user can set up a glob for
interfaces to be automatically added (eg tap*).
