NextBSD/src 9750eb8sys/dev/netmap netmap_pt.c netmap_generic.c, sys/net netmap_virt.h netmap.h

remove stale and unused code from various files
fix build on 32 bit platforms
simplify logic in netmap_virt.h

The commands (in net/netmap.h) to configure communication with the
hypervisor may be revised soon.
At the moment they are unused so this will not be a change of API.
