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.

Add a setlocale() call and use strftime().
Use err() instead of fprintf + exit.
Check for extraenous arguments and complain.

Sort option descriptions. Use more macros. New sentence, new line.
Add missing .El.

Patches from Liam Foy to:

- Use realloc instead of allocating 1000 structures.
- Remove NUSERS nonsense. If this is kept, shouldn't
who(1) comply with it too?
- Be consistent with who(1). Add two identical options
from who(1). These are -q and -H.
- General Cleans:
- Move globals into local scope
- Re-write a macro to remove an uneccessary
variable.
- Use UT_NAMESIZE.
- Remove unecessary header etc.

And from me, KNF, pass lint.

According to rwhod(8), file names are actually /var/rwho/whod.*

More and more .Os cleanups. .Os is defined in the tmac.doc-common file,
so we shouldn't override it with versions in the manpages. Many more to
