Bump libutil for new pidfile functions.

Add kinfo_getvmmap from FreeBSD

Bump shlib minor for new function: ereallocarr(3)

Noted by <mrg>

- add getdiskrawname.
- exit on error for lint.

add getfsspecname

branches: 1.49.2;
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 strpct, requested by joerg

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

branches: 1.46.2;
merge christos-time_t

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: 1.44.4;
add estrndup()

Add support for per-user /tmp.

Enabled via per_user_tmp in /etc/rc.conf (default off).

See security(8) and rc.conf(5) for more details.

Lots of input from thorpej@ & christos@, thanks!

Complete the move of string_to_flags() and flags_to_string() from the
bin/ls sources to libutil:
o Bump libutil minor version number
o Fix uses to include <util.h> to pick up the function definitions
o Fix most uses of flags_to_string() to release the now-malloc()ed result

add getdate.

Add efun(3)

Some stuff that's been sitting in my tree for too long...

Improve the pw_policy(3) API by splitting it to two functions, one to load
the policy from /etc/passwd.conf and another to test passwords against the
policy.

Some bug fixes, more consistent code, and man-page updates.

Minor for libutil bumped.

make setuserenv and setuserpath take an environment setting function and
an environment pointer and expose them.
bump version.

Introduce pw_policy(3), an easily extendable way of defining password
policies and enforcing them in programs.

Man-page written with much help and tips from David Maxwell, Hubert
Feyrer, and Thomas Klausner.

This bumps libutil minor to 7.

XXX: Need default policy to go in /etc/passwd.conf, and integration
into local/yp/PAM password changing code.

PR/10206.

add pw_getpwconf(), bump.

Add sockaddr_snprintf; XXX: Needs a man page.

- 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.

add functions to retrieve option values.

move getmntopts(3) to libutil, build and install also it's manpage
bump libutil minor
adjust individual mount_*/Makefile to use libutil getmntopts(3)

Bump minor number for getlabel{sector,offset}() addition.

- 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 snprintb(3) inspired from bitmask_snprintf(9), but made to look like
more like snprintf(3). Discussed with thorpej.

Bump minor number to 3 because there are already systems with
"libutil.so.6.2" to avoid further problems.

Move humanize_number(3) from libutil to libc as per discussion on tech-misc
Revert minor number bump on libutil (with note to skip it next update), and
bump libc.

Actually bump the shlib version to 6.2 as abs intended to.

add utmpx/wtmpx processing routines.

branches: 1.24.2;
Bump libutil major for pw_mkdb() change.

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.

Bump libutil minor (pw_getconf()).

branches: 1.20.4;
Add necessary support routines for login.conf.

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

Add a note to update src/distrib/sets/lists/base/shl.*, and add a missing
RCS Id.

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.

Put pw_scan() back into libutil and pretent that libutil.so.5.0 never
existed.

actually, bump major for pw_scan() removal, even when it was moved to -lc

bump minor (because pw_scan() moved to libc, and old binaries that use libutil.so.4.4 and libc.so.12.26 won't work otherwise)

Add bswap{16,32,64} functions to libutil. Because of this, bump minor.

RCSID Police.

Increase minor number for fparseln

Add pidlock, ttylock, ttyunlock functions.

implement opendisk(3), as discussed with Jason Thorpe

Change pw_copy to take an optional 4th parameter (old_pw), a pointer
to a passwd structure. If a good pointer, make sure old entry in file
is identical to passed passwd (old_pw). If not, abort.

Update documentation, bump major version due to change to pw_copy.

Increment minor version for new function ttyaction().

Minor reorganization of libutil, including the addition of passward
locking and editing functions.
From Greg Hudson <ghudson@MIT.EDU>

minor cleanup; kill unnecessary casts

_double_ major number bump! joy!

get rid of stuff that doesn't belong here

kill the 'prog' arg to getbsize(); it's unneeded. minor rev bump.

add shlib_version file, with version 0.0
