bsd.own.mk: rename GCC_NO_* to CC_WNO_*

Rename compiler-warning-disable variables from
GCC_NO_warning
to
CC_WNO_warning
where warning is the full warning name as used by the compiler.

GCC_NO_IMPLICIT_FALLTHRU is CC_WNO_IMPLICIT_FALLTHROUGH

Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.

introduce some common variables for use in GCC warning disables:

GCC_NO_FORMAT_TRUNCATION -Wno-format-truncation (GCC 7/8)
GCC_NO_STRINGOP_TRUNCATION -Wno-stringop-truncation (GCC 8)
GCC_NO_STRINGOP_OVERFLOW -Wno-stringop-overflow (GCC 8)
GCC_NO_CAST_FUNCTION_TYPE -Wno-cast-function-type (GCC 8)

use these to turn off warnings for most GCC-8 complaints. many
of these are false positives, most of the real bugs are already
commited, or are yet to come.


we plan to introduce versions of (some?) of these that use the
"-Wno-error=" form, which still displays the warnings but does
not make it an error, and all of the above will be re-considered
as either being "fix me" (warning still displayed) or "warning
is wrong."

branches: 1.7.20;
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.

From Liam Foy:
- Print uptime in secs if uptime is less than 1 minute
- If at least one call to onehost() fails, return one (allows for external error detection)
- Avoid leaks, use clnt_destroy (from OpenBSD)
- err(3) cleans
From me:
- lint cleanups
- more KNF

RCS id police.

specify man pages the new way.

Add RCS identifiers, remove some completely useless RCS logs and patchkit
headers, and a few other insignificant changes.

No need to link with -lrpc

Add rup and rusers. Changes to rwall

src is too big these days to tolerate superfluous apostrophes. It's
"its", people!

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22365, verified by myself.

New sentence, new line.

Use standard headers, punctuation nit.

Whitespace cleanup.

Substitute the cross reference to portmap(8) with rpcbind(8).

branches: 1.12.10;
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
come.

s/bzero/memset, fix .Nm usage

RCS id police.

Fix spelling errors.

Implemented sorting options found in Sun's rup.

more sane output.
option -t: print remote-host's time

Add cross references to "SEE ALSO" section.

Change Sun-OS to SunOS. Every other instance of in manual our manual
is typeset that way.

Add RCS identifiers, remove some completely useless RCS logs and patchkit
headers, and a few other insignificant changes.

Fix man page.

Cleanup man page; convert to mandoc.

Add rup and rusers. Changes to rwall

Drop main() prototype.

Apply casts to cases where xdrproc_t is expected but is not
strictly passed, for example because the second argument is
a different kind of pointer.

convert __attribute__s to applicable cdefs.h macros

Homogenize usage messages: make the 'usage' word all lowercase, as this seems
to be the most common practice in our tree.

safer use of realloc

Don't declare 'extern opt*' getopt variables.

Remove spurious ^L, as per bin/9574 by Thilo Manske.
While here, const poison a little.

If printing of a host's time is requested via the -d switch, condense
output so it doesn't exceed 80 columns.

Patch submitted in PR 5933 by Tim Rightnour <root@garbled.net>

If up for one minute, report "1 min, " not "1 mins,".

add includes to fix compiler warning

s/bzero/memset, fix .Nm usage

Fix compiler warnings (because new prototypes came into scope
with latest "rpc.h" changes). It's -Wall ready now.

make rup handle uptimes of more than 1 year per pr-3060

RCS id police.

Correct time display for 12:xx case.
From Dave Huang <khym@bga.com>, PR #2734.

clnt_call requires timeval argument

Implemented sorting options found in Sun's rup.

put -t in the usage line

more sane output.
option -t: print remote-host's time

Make sure we use rstat's protocol's values of FSCALE. We were picking up
the FSCALE from sys/param.h which caused all of the load averages from
remote machines to be incorrect.

Add RCS identifiers, remove some completely useless RCS logs and patchkit
headers, and a few other insignificant changes.

Line buffer output to work better with more.

Fix calling clnt_sperror()

Widen host name.
