Teach pw(8) about how to use pw/gr API to reduce code duplication

MFC after: 2 months

Add the groupmod '-d' option to pw to allow the deletion of existing users
from a group without the need to perform the same operation by replacing
the existing list via the '-M' option. The '-M' option requires someone
to fetch the existing members with pw, deleting the undesired members from
the list and sending the altered list back to pw.

encrypted password on the specified file descriptor.

Localize time/date.
Use ISO 8601 date in logs.
Fix wrong argument type in ctype functions.

Portability fixes for other bsd4.4 derivatives.

Add new functionality "lock" and "unlock" to provide a simple password
locking mechanism for users. This works by prepending the string
"*LOCKED*" to the password field in master.passwd to prevent successful
decoding.

Clean up error handling in fileupdate(), which now returns 0 on success
instead of a boolean. This replicated through he front-end sub-functions
relating to add, delete, modify entries in passwd & group files
Errno is now preserved so output of errc()/warnc() will be less obfuscated
by subsequent errors when reporting the problem.

Add more intelligent error handling when attempting to modify/delete NIS
entries with no corresponding local database entry.

[MFC to stable in a couple of weeks to keep both in sync]

$Id$ -> $FreeBSD$

1) Do not blindly ignore file update errors which may occur due to concurrent
updating
2) Add -V <etcdir>, which allows maintaining user/group database in alternate
locations other than /etc.

Use err(3) instead of local redefinition. Add rcsid string.

Revert $FreeBSD$ to $Id$

Yet another formatting consistency check.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

1) 200 users per group limitation removed and pw
will handle lines of any length in /etc/group.
2) Fixed bug with usermod -d not updating user's home
directory.
3) Minor formatting display changes/fixes with *show -P.

Allow 8-bit characters in the passwd gecos field, and adds a paragraph
to the mangpage explaining the consequences (to be updated at a later
date after login class conf support is added).

This commit was generated by cvs2svn to compensate for changes in r20302,
which included commits to RCS files with non-trunk default branches.

Copyright update by the author, to be more in line with our sample

Upgrade from the author, reflecting all my wishes resulting out of the
sysinstall use of this tool (plus some bug fixes).

2.2 candidate...

pw(8) -- a backend utility to manage the user and group databases.

sysinstall's new User&group menu will use it, hence it's a 2.2
candidate despite of providing new functionality.
