Allow loadable interface drivers with BPF support to be loaded into a kernel that doesn't have it. This is achieved by having minimal do-nothing stubs enabled when there are no bpfilter devices configured. Driver modules should be built with BPF enabled for maximum convenience (but can be built without it for maximum performance).

The discard, tunnel, SLIP, and PPP network interface pseudo-devices are now dynamically loadable. It doesn't make sense to do the same for the loopback.

Sample initial set of kld-ified modules. Not all have been completely converted yet. These are more of a starting point. This is NOT connected to the parent Makefile. OK'ed by jkh (who is ever so patiently waiting)

Undo #undef KERNEL hack for vnode.h to avoid vnode_if.h. XXX It probably makes sense to have a flag for bsd.kern.mk to avoid these rules. XXX IO_NDELAY seems to be the main reason for it, when used in a cdevsw read or write "flag" context. Perhaps a redundant declaration somewhere like sys/conf.h might help remove the need for vnode.h in these device drivers in the first place.
