Much cleaner sync with NetBSD. Some #if defined() magic has been sent in the

form of a diff to augustss@netbsd.org so that future syncs will be very easy.
This commit also adds support for ADMtek AN986 "Pegasus" based USB Ethernet,
CATC USB-EL1210A based USB Ethernet, and USB Printers (all untested).
