75ff053010 Make netstat build again. I don't see why it has any business dumping 
the raw contents of tcpcb but that's another story.

4147a3c54a Add new Makefile knob, USE_FORT, which extends USE_SSP by turning on the 
FORTIFY_SOURCE feature of libssp, thus checking the size of arguments to
various string and memory copy and set functions (as well as a few system
calls and other miscellany) where known at function entry.  RedHat has
evidently built all "core system packages" with this option for some time.

This option should be used at the top of Makefiles (or Makefile.inc where
this is used for subdirectories) but after any setting of LIB.

This is only useful for userland code, and cannot be used in libc or in
any code which includes the libc internals, because it overrides certain
libc functions with macros.  Some effort has been made to make USE_FORT=yes
work correctly for a full-system build by having the bsd.sys.mk logic
disable the feature where it should not be used (libc, libssp iteself,
the kernel) but no attempt has been made to build the entire system with
USE_FORT and doing so will doubtless expose numerous bugs and misfeatures.

Adjust the system build so that all programs and libraries that are setuid,
directly handle network data (including serial comm data), perform
authentication, or appear likely to have (or have a history of having)
data-driven bugs (e.g. file(1)) are built with USE_FORT=yes by default,
with the exception of libc, which cannot use USE_FORT and thus uses
only USE_SSP by default.  Tested on i386 with no ill results; USE_FORT=no
per-directory or in a system build will disable if desired.

65305bdc98 Good intentions are still intentions. If we can't open kvm, but we still 
have sysctl, it's still not enough for -P. A groveler is a groveler is
a groveler.

On a different note, this code needs a rewrite.

32f8a691e7 - Back to using kvm if we have access to it, since the sysctl stats do not

5d7aa1a613 Make netstat use sysctl when dumping routing tables/stats. 
Heavily based on similar code from Claudio Jeker (at OpenBSD).

While here, fix inet/inet6 sysctl stuff commited previously to
actually work, and some other nits to make netstat more sysctl
friendly.

One step closer to losing setgid kmem on this one...
