Remove support for the /dev/net/* per-interface devices. They serve

little purpose and are unused in the base system.

The IOCTL functionality is entirely duplicated and routing sockets
provide a richer interface than the kqueue functionality.

Further, it is not practical for these devices to be made sensible in
the face of VIMAGE.

Bump __FreeBSD_version on the off chance that there is any code out
there that actually uses this stuff.
