Interface glob to automatically add to the bridge

commit log

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*).
