Add if_gre module glue.

# $FreeBSD$
Fix a bug whereby the physical endpoints of a gre(4) tunnel would not be printed, if the module were loaded into a kernel which had INET6 enabled. The gre(4) driver does not use INET6, nor is it specified for IPv6. The tunnel_status() function in ifconfig(8) is somewhat overzealous and assumes that all tunnel interfaces speak KAME ifioctls. This fix follows the path of least resistance, by teaching gre(4) about the two KAME ifioctls concerned. PR: bin/56341

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); PR: 164475 Differential Revision: D1023 No objections from: net@ Relnotes: yes Sponsored by: Yandex LLC

SRCS= if_gre.c opt_inet.h opt_inet6.h
After r274246 make the tree compile again. gcc requires variables to be initialised in two places. One of them is correctly used only under the same conditional though. For module builds properly check if the kernel supports INET or INET6, as otherwise various mips kernels without IPv6 support would fail to build.
