PR lib/59811 allow any rounding in strpct(3).

Add str[s]pct_r (same as str[s]pct with an addition "how to round" param) and
strpct_round to set the rounding used by the older str[s]pct functions.
The default remains rounding down (toward zero) for compatibility.

See the PR (and the updated man page) for the details.

For df(1) use "round away from zero" mode, as POSIX requires.

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.

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
