Scott Long 2bc6081c9f Reintroduce the lmc T1/E1/T3 WAN driver. This version is locked, supports 
interface polling, compiles on 64-bit platforms, and compiles on NetBSD,
OpenBSD, BSD/OS, and Linux.  Woo!  Thanks to David Boggs for providing this
driver.

Altq, sppp, netgraph, and bpf are required for this driver to operate.
Userland tools and man pages will be committed next.
