Remove IPsec and related code from the system.

It was unmaintained ever since we inherited it from FreeBSD 4.8.

FAST_IPSEC

Remove IPsec and related code from the system.

It was unmaintained ever since we inherited it from FreeBSD 4.8.

In fact, we had two implementations from that time: IPSEC and FAST_IPSEC.
FAST_IPSEC is the implementation to which FreeBSD has moved since, but
it didn't even build in DragonFly.

Fixes for dports have been committed to DeltaPorts.

* Remove if_sl, if_ppp, and if_faith from the kernel build. These
interfaces may be loaded as modules.

* Add missing MODULE_VERSION for if_sl and if_ppp. This allows these
modules to be specified in /boot/loader.conf without crashing the
kernel if the kernel already happens to build them in, for forwards
and backwards run-time compatibility.

Unbreak VKERNEL64 build.

After a05cac6 removal of MAKEBOOTDEV and B_ flags from sys/reboot.h
(that is not the place for such things) I broken the VKERNEL64 build.

This is a quick fix before someone with basic motoric functions
and a heart beat will take a better look (I lack the latter).

Not sure if disabling FFS_ROOT breaks anything, but it is better
than having build errors on vkernel/x86_64/autoconf.c

Also it gave me an oportunity to finally go through procedure
described in vkernel(7) to test it out for the first time!
So far no side effects on both X86_64_NON_GENERIC and VKERNEL64
except for no longer printed "no B_DEVMAGIC (bootdev=0)" in dmesg.

I should have guarded MAKEBOOTDEV and B_ flags with __i386__ in
sys/platform/pc64/include/bootinfo.h cause there is no platform/pc32
and I'm pretty sure thats a i386 thing only.

kernel: Make sysvipc syscalls non-optional.

Before this commit, we had three related kernel options, SYSVMSG,
SYSVSEM and SYSVSHM, to enable the syscalls. They were in all our
configs, but in theory the user could disable the functionality.
Having to deal with scenarios where they are not available is
unnecessarily complicated and there seems to be no real reason to
want to disable them.

For convenience, leave the three options as no-ops for now, so
adjusting the kernel config is not necessarily needed. We'll
change them to being unknown at some later point.

This commit also removes some parts which assumed that we had
sysvmsg.ko, sysvsem.ko and sysvshm.ko modules, like FreeBSD, but
this assumption was never true on DragonFly.
