	sys/net        : if_gre.c if_gre.h 

Log message:
- Add IPv6 over GRE.
- u_short -> u_int16_t
- Change default MTU to 1476 (same value that Cisco and other *BSD's use).
- Mark gre(4) interfaces as IFT_TUNNEL (Encapsulation interface).

>From NetBSD

- Support setting the MTU

Be very careful when upgrading, the change in default MTU might cause
problems with an existing OpenBSD <-> OpenBSD setup.
