MFC r316699: Do not adjust interface MTU automatically. Leave this task to the system administrator.
Before r274246 interface MTU was adjusted only when GRE key is configured. The r274246 has changed this behavior to automatically adjust MTU when any option, that changes the size of GRE header is configured. This patch removes automatic MTU adjustment from if_gre(4) and if_me(4), and restores the behavior that was prior to r274246.

Add new socket ioctls SIOC[SG]TUNFIB to set FIB number of encapsulated packets on tunnel interfaces. Add support of these ioctls to gre(4), gif(4) and me(4) interfaces. For incoming packets M_SETFIB() should use if_fib value from ifnet structure, use proper value in gre(4) and me(4).

Overhaul if_gre(4).
Split it into two modules: if_gre(4) for GRE encapsulation and if_me(4) for minimal encapsulation within IP.
gre(4) changes: * convert to if_transmit; * rework locking: protect access to softc with rmlock, protect from concurrent ioctls with sx lock; * correct interface accounting for outgoing datagramms (count only payload size); * implement generic support for using IPv6 as delivery header; * make implementation conform to the RFC 2784 and partially to RFC 2890; * add support for GRE checksums - calculate for outgoing datagramms and check for inconming datagramms; * add support for sending sequence number in GRE header; * remove support of cached routes. This fixes problem, when gre(4) doesn't work at system startup. But this also removes support for having tunnels with the same addresses for inner and outer header. * deprecate support for various GREXXX ioctls, that doesn't used in FreeBSD. Use our standard ioctls for tunnels.
me(4): * implementation conform to RFC 2004; * use if_transmit; * use the same locking model as gre(4);
