Add support for divert sockets. They allow you to:

- queue packets from pf(4) to a userspace application
- reinject packets from the application into the kernel stack.

The divert socket can be bound to a special "divert port" and will
receive every packet diverted to that port by pf(4).

The pf syntax is pretty simple, e.g.:

pass on em0 inet proto tcp from any to any port 80 divert-packet port 8000

test, bugfix and ok by reyk@
manpage help and ok by jmc@
no objections from many others.
