Add pair(4), a vether-based virtual Ethernet driver to interconnect
rdomains and bridges on the local system. This can be used to route
through local rdomains, to create L2 devices (like trunks) between
them, and many other things.
Discussed with many, with input from mpi@
OK sthen@ phessler@ yasuoka@ mikeb@
