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."

Remove the userland part of ISDN. The kernel part is untouched for now.
ipppctl was actually an exact copy of pppoectl; there is no functional
change in pppoectl in this commit.

branches: 1.3.76; 1.3.78;
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.

Rename ISDN devices, per discussion on tech-kern. The network devices
become ippp (ISDN ppp) and irip (ISDN raw IP). The character device now
are called: /dev/isdn (isdnd <-> kernel communication), /dev/isdnctl (dialing
and other control), /dev/isdntrc* (tracing), /dev/isdnbchan* (raw B channel
access, i.e. for user land PPP) and /dev/isdntel* (telephone devices, i.e.
for answering machines).

Move /usr/sbin/pppoectl to /sbin/pppoectl, so we can call it from
ifconfig.pppoe* files.

Rename the source directory and files to match the primary purpose
of this utility - probably noone is using this for ISDN now anymore,
as isdnd has simpler ways to acomplish the same.

Fix wrong macro, use An.

Bump date.

fix the date.

Two small fixes from David H. Gutteridge in PR bin/45454.

Kill stray t.

Assume o umlaut is transliterated by nroff as needed.
\\ -> \e

Fix preamble to match order set out by mdoc(7). Discussed with wiz.

PR/29457: Joachim Kuebart: pppoectl's config file does not allow # in passwords
Fixed, by passing FPARSELN_UNESCALL in parsing.

Bump date for previous.

use netmask of /32. as discusssed on tech-userlevel

Punctuation nits.

Make LCP keepalive behaviour configurable.

bump .Dt [from wiz]

add a "-f configfile" option. the config file contains individual lines of
parameter=value pairs normally passed on the command line (# and \
continuation also works, yay fparseln), one per line. now you don't have
to run a program with a password on the command line.

Drop trailing whitespace.

It's ipppctl not ipppcontrol ...
Also add synopsis for ipppctl.

New sentence, new line. By Robert Elz with minimal fixes.

Grammar improvement.

Add a "clear-auth-failure" command to reset the authentication failure
count without changing any (local) authentication settings.

Fixes kern/18071 ( without any kernel change ;-) )

Fix copyright notice, sprinkle some $NetBSD$.

Typo fix.

Whitespace nit.

Add a "query-dns" parameter to tell the interface we would like to get
DNS settings from the peer and a "-n" option to retrieve the results
after the PPP connection is established.

Xref pppoe(4) and ifwatchd(8).

Display the authentication failure count (if non zero) and make the
limit settable.

Fix two typos and a whitespace nit.

Make idle timeout settable and display it.
Bring the man page closer to reality.

Lots of grammar fixes and other slight improvements.

Remove duplicate static.

static + __dead

Fix memset usage.

Check for allocation failures in malloc, calloc, realloc, asprintf, and
vasprintf and try to handle them.

Move WARNS=3 to the Makefile.inc, and add a little const to the remaining

Partly back out previous - do not free the linebuffer while still having
pointers into parts of it. Add a comment explaining why we prefer to
leak memory ;-)
Fixes PR bin/30174.

Skip empty lines, and free the line buffer so that we don't leak.
