Fix sign-compare issues

branches: 1.21.20;
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.

Remove some more old kerberos4 code.

Merge a bunch of things from crypto-us and crypto-intl into basesrc,

bsd.crypto.mk.

There is still a bunch more work to do, but crypto is now more-or-less
fully merged into the base NetBSD distribution.

optionally include CRYPTOPATH Makefile.frag files.

Use bsd.crypto.mk.

Remove the crypto-related bits until such time as we have a fully-
integrated source tree. Export-controlled versions of these are now
built during the domestic build process.

.Nm does not need a dummy argument ("") before punctuation or
for correct formatting of the SYNOPSIS any longer.

"Utilize" has exactly the same meaning as "use," but it is more
difficult to read and understand. Most manuals of English style
therefore say that you should use "use".

revert rev 1.45:
"PR/54435: Adjust for new kernel behavior of soreceive(9) clearing MSG_OOB"

That change was trying to make rlogin work again after the SIOCATMARK ioctl
was broken, but that kernel bug has now been fixed, so the original rlogin code
now works again. Further, the changed rlogin code actually did the wrong thing,
by treating reception of the MSG_OOB byte as meaning that we are now
"at the mark", but that is not true... we are "at the mark" only when
we have reached the point in the stream where the MSG_OOB byte was originally,
as indicated by SIOCATMARK. So going back to the previous code seems best
all around. ok'd by christos.

PR/54435: Adjust for new kernel behavior of soreceive(9) clearing MSG_OOB
when receiving the oob message. This made SIOCATMARK return always 0 since
the oob message was cleared. Instead, use recvmsg(2) to determine if
the message was oob or not. This works with both the old and new kernel
and it is not racy.

(foo *) 0 -> NULL
int -> ssize_t/size_t

msg:
avoid passing the same pointer in multiple arguments for restrict
marked arguments:
- sigaction() wants separate in/out
- use memmove() not memcpy() for overlapping regions (this may fix
a real bug in nvi -- but it seems unlikely)
- select() wants separate read/write/except
- sigprocmask() wants separate set/oset
