Implement pidfile_lock, pidfile_read and pidfile_clean.

Discussed on tech-net@, ok core@.

add kinfo_getvmmap() decl

Add ereallocarr(3) to libutil

ereallocarr(3) wraps reallocarr(3) and embeds return status validation.

Older version reviewed by <riastradh> and <christos>

add estrto{i,u} (Kamil Rytarowski)

Add getbyteorder(void) prototype.

Over the years this header gained a lot of disparate functionality
and willy nilly people kept adding headers appropriate to the new
functionality So we reached where we are today, this header causes
lots of namespace conflicts (for example you cannot use util.h from
a lex file, because ECHO is macro used in lex, and ECHO is defined
to 8 in termios). Roll back time, and remove all the unnecessary
includes, leaving it to the program to include the ancillary headers
they need.

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.

prototype for strpct

pw_error is documented to be dead

Retire varargs.h support. Move machine/stdarg.h logic into MI
sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.

Consistently use __printflike and __scanflike.

branches: 1.54.2;
retire pw_policy(3) -- it is not found useful, there are other
(more common) ways to enforce a password strength policy
approved by elad

In a furious blaze of *facepalm* / "what was i thinking?", fix the
open routine function pointer prototype of opendisk1() to match
the prototype of open().

Add opendisk1(), which functions like opendisk(), but takes a function
pointer to the routine to be used for open().

Implement snprintb_m(3) to provide multi-line bit/bit-field decode.
Discussed on tech-kern.

merge christos-time_t

branches: 1.49.12; 1.49.14; 1.49.18;
humanize_number was the only function in <util.h> that is not in libutil.
Move it to stdlib.h and add dehumanize_number.

don't use u_long because it is present only with _NETBSD_SOURCE

Add raise_default_signal(3) -- raise the default signal handler.
Can be used by applications that have their own SIGINT (et al)
handlers and want to exit in a manner that correctly
signals to the parent that the process was terminated by a signal.
See http://www.cons.org/cracauer/sigint.html for more info.
Discussed on tech-userlevel@.

branches: 1.46.4;
add estrndup()

moved string_to_flags and flags_to_string from ls to libutil.

getdate -> parsedate

constify getdate

add getdate.

Add efun(3)

Don't expose struct pw_policy and use pw_policy_t, use malloc, man-page
fixups.

As discussed on source-changes@.

Okay yamt@, thorpej@.

Add the struct pw_policy forgotten in previous commit.

Forgot these when imported pw_policy(3).
Thanks to Hisashi T Fujinaka for noticing.

Get rid of the #if !HAVE_NBTOOL_CONFIG_H kludge. None of host tools
uses this header now.

Make disklabel(8) and fdisk(8) into "host tools " last step: build
and install ${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-disklabel,
${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-fdisk by "reaching over" to
the sources in ${NETBSDSRCDIR}/sbin/{disklabel fdisk}/.

To avoid clashes with a build-host's header files, especially on
*BSD, the host-tools versions of fdisk and disklabel search for
#includes such as disklabel.h, disklabel_acorn.h, disklabel_gpt.h,
and bootinfo.h in a new #includes namespace, nbinclude/. That is,
they #include <nbinclude/sys/disklabel.h>, <nbinclude/machine/disklabel.h>,
<nbinclude/sparc64/disklabel.h>, instead of <sys/disklabel.h> and
such. I have also updated the system headers to #include from
nbinclude/-space when HAVE_NBTOOL_CONFIG_H is #defined.

u_short -> uint16_t

add pw_getpwconf()

Add sockaddr_snprintf()

- Rename pw_copy() to pw_copyx(), make it return a success/failure code,
and add "errbuf" and "errbufsz" parameters so that errors can be handled
gracefully, rather than simply exiting the process.
- Add a pw_copy() wrapper around pw_copyx() to preserve old behavior for
apps that use it.
- Bump shlib version to 7.4.

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

Patches provided by Joel Baker in PR 22270, verified by myself.

Bump daddr_t to 64 bits. Replace it with int32_t in all places where
it was used on-disk, so that on-disk formats remain the same.
Remove ufs_daddr_t and ufs_lbn_t for the time being.

Add getlabelsector() and getlabeloffset() as wrappers around the
KERN_LABELSECTOR and KERN_LABELOFFSET sysctls.

- Migrate fparseln(3) from libutil to libc, where it should have been in
the first place...
- Bump libutil major (to 7.0) and libc minor (to 12.91).

add prototypes for disklabel_dkcksum() and disklabel_scan().

Add snprintb(3)

Cosmetic changes.

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

add utmpx/wtmpx processing routines

change return type of pidfile(3) to int (-1 on error), to inform caller
of errors. behavior now in sync with openbsd implementation.
(see tech-userlevel and bsd-api-discuss)

branches: 1.21.2;
Add two arguments to pw_mkdb(), a la OpenBSD. This is to allow us to pass
the -u and -s options to pwd_mkdb.

add getbootfile(3)

branches: 1.19.2;
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.

- Sort function decls.
- Remove duplicate decl.
- First arg to secure_path() is now constant.

Remove decl for parseuserspec(), a local modification which acidentally got
comitted.

- Declare pw_getconf().
- ANSIfy.

branches: 1.15.4;
Add necessary support routines for login.conf.

- provide forward struct declarations for all functions.
- const poison login().
- XXX: we should not include all these files here. We only need stdio.h and
sys/types.h! But I am not rm'ing them now because too many things will break.

Add pidfile(3), which write a pid file in /var/run, and arranges for it
to be removed on normal exit.

const poisoning.

move pw_scan from util.h to pwd.h, add _PASSWORD_{OLDFMT,NOWARN} flags

add flags arg to fparseln(), and define FPARSELN_UNESC{ESC,CONT,COMM,REST,ALL}

fix retval of fparseln

Add fparseln(3)

Add prototypes and defines for pidlock/ttylock/ttyunlock.

implement opendisk(3), as discussed with Jason Thorpe

Update pw_copy prototype for changes for PR3806, 3807.

forgot to commit this.

Add declaration for ttyaction().

Prototypes for getmaxpartitions(3) and getrawpartition(3).

Added new header files for functions in libutil.
Added macro for master passwd lock file.
