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.

Explicitly move setting of NOxxx and USE_SHLIBDIR to the top of the
Makefile (before including <bsd.own.mk>)

Readability cleanups; MKfoo=no -> NOfoo.

More include cleanup. Remvoe (p) from #undef in libipsec.

convert from NOxxx= to MKxxx=no.
include <bsd.own.mk> if testing a MKxxx variable.

- define WARNS?=1 in the top-level Makefile.inc, and don't define
anywhere else.
- for now, override WARNS=0 in librpcsvc and libwrap, until they're
cleaned up
- rcsid police

lib is now clean (except for librpcsvc and libwrap) on the i386, and
this should motivate the other ports to fix any other minor problems
that their compilers pick up that the i386 version doesn't.

PR/38413: Takahiro Kambe: mt(1) print some junk output when using remote tape
Not all fields are valid in the ioctl to get tape info in the rmt protocol.
Zero out the struct so that we don't print junk.
While here, KNF.

Improve isrmt() check: it cannot be a rmt fd if there are no pipes
open for the fd. Prevents collision with rumphijack.

Also, prevent potential hyperspace memory access.

Does someone want to write tests for this facility?

WARNS=2 fixes

Negative exit code cleanup: Replace exit(-x) with exit(x).
As seen on tech-userlevel.

Make this file compile again on alpha; size_t isn't always same size as int.

More cosmetic changes.

convert to ANSI KNF

back out the #ifdef _DIAGNOSTIC argument checks; too many people complained.
_DIAGASSERT() is still retained.

* use _DIAGASSERT() to check pointer arguments against NULL and file
descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.

the first two items result in the addition of code similar to the
following in various functions:

_DIAGASSERT(path != NULL)
#ifdef _DIAGNOSTIC
if (path == NULL) {
errno = EFAULT;
return (-1);
}
#endif

More trailing white space.

- support RCMD_CMD, ala rcmd(3).
- put paths for rsh and rmt into "pathnames.h"
- document this.

- Convert a few functions to variable arguments so that they can be
prototyped like the functions that they remap (open, fcntl, ioctl).
- Pull in prototypes from <rmt.h>.

branches: 1.8.2;
clean up WARNS on the alpha.

gcc -Wall fixes, including: end unterminated comment (!), add braces
to Ctp and Ptc array initializers, fix sprintf() format in
_rmt_lseek(), add explicit return type for _rmt_ioctl(), and move
isrmt() definition so that it's defined before it's used.

- convert unsafe strcpy(), strcat() and sprintf() to the `n' versions.
- some KNF.

Change an instance of "int" to "unsigned long" (the correct type for
ioctl commands under NetBSD) so that this compiles on the Alpha.
