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.

lint: warn about extern declarations outside headers

https://mail-index.netbsd.org/tech-userlevel/2023/03/15/msg013727.html

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."

-Wstringop-truncation is only gcc.

Ignore strncpy(foo, bar, sizeof(foo)) for the wtmp fields where we don't
want NUL termination. We can't use pragma's because the old gcc complains
about the new warnings it does not understand.

Add getlabelusesmbr(), as proposed in
http://mail-index.netbsd.org/tech-userlevel/2011/08/25/msg005404.html
This is used by disk tools such as disklabel(8) to dynamically decide is
the undelyling platform uses a disklabel-in-mbr-partition or not
(instead of using a compile-time list of ports).
getlabelusesmbr() reads the sysctl kern.labelusesmbr, takes its value from the
machdep #define LABELUSESMBR.
For evbmips, make LABELUSESMBR 1 if the platform uses pmon
as bootloader, and 0 (the previous value) otherwise.

Add humanize_number.3 from Tomas Svensson in PR lib/15508.
Bump version of libutil

branches: 1.32.2;
* Add user-controlled mk.conf variables
- SHLIBDIR Location to install shared libraries if ${USE_SHLIBDIR}
is "yes". Defaults to "/usr/lib".

- USE_SHLIBDIR If "yes", install shared libraries in ${SHLIBDIR}
instead of ${LIBDIR}. Defaults to "no".
Sets ${_LIBSODIR} to the appropriate value.
This may be set by individual Makefiles as well.

- SHLINKDIR Location of shared linker. Defaults to "/usr/libexec".
If != "/usr/libexec", change the dynamic-linker
encoded in shared programs

* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
libtermcap libutil libz

* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
to ${_LIBSODIR}/${LIB}.so* for compatibility.

* Always install /sbin/init statically (for now)


The net effect of these changes depends on how the variables are set:

1.) If nothing is set or changed, there is no change from the
current behaviour:
- Static /bin, /sbin, and bits of /usr/*
- Dynamic rest
- Shared linker is /usr/libexec/ld*so

2.) If the following make variables are set:
LDSTATIC=
SHLINKDIR=/lib
SHLIBDIR=/lib
Then the behaviour becomes:
- Dynamic tools
- .so libraries used by /bin and /sbin are installed to /lib,
with symlinks from /usr/lib/lib*so to -> /lib/lib*so
where appropriate
- Shared linker is /lib/ld*so

3.) As per 2.), but add the following variable:
USE_SHLIBDIR=yes
This forces all .so's to be instaleld in /lib (with compat
symlinks), not just those tagged by their Makefiles to be.
Again, compat symlinks are installed

Add a catch-all man page for libutil.

Rename secure_path(3) source file from securepath.c to secure_path.c.

Add getbootfile(3) to libutil, and a man page.
Bump libutil version to 5.5.

Add two new passwd file update functions:
- The pw_setprefix() function defines the root directory used for passwd
file updates. If the prefix is set to /newroot pw_lock() will operate on
/newroot/etc/ptmp afterwards. The default prefix is an empty string.
- The pw_getprefix() function returns the root directory which is currently
used for passwd file updates.

rename securepath.3 into secure_path.3, as the function is named secure_path().
it is too hard to guess...

More trailing white space.

Add pidfile(3), which write a pid file in /var/run, and arranges for it

Move the bswap functions from libutil to libc (this bups the
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.

Kill __LIBUTIL_BUILD in favor of the newly added _LIBC indicator completely;

Add pidlock, ttylock, ttyunlock functions.

- define WARNS?=1 in the top-level Makefile.inc, and don't define

- 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.

WARNSify

implement opendisk(3), as discussed with Jason Thorpe

Add ttymsg.3 to the man pages.

- RCSID police

Add ttyaction.3 and ttyaction.c

Add two functions to libutil:

- getmaxpartitions: get the value of MAXPARTITIONS for the
currently running system

- getrawpartition: get the value of RAW_PART for the
currently running system

These functions are necessary since the value of MAXPARTITIONS might
be different across platforms which are binary compatible (e.g. amiga
and sun3).

Minor reorganization of libutil, including the addition of passward
locking and editing functions.
