fc1007e186 Shift file locking to source file instead of temp file. This fixes
data buffering issue that corrupts files if two pw(8)'s run at the
same time as well as changing pw(8) so it uses the same locking
mechanism as PAM, vipw(8), pwd_mkdb(8), etc.

c190a0f584 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]

5f12594a29 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.

73375325b1 Fix race condition in pw caused by multiple instances of pwd_mkdb being
run at the same time.

Notes:
    The fileupdate function is still somewhat broken.  Instead of
    returning a failure code if it can't modify the original file it
    renames the .new file and continues as though nothing is wrong.
    This will cause the lock on the original file to be lost and could
    lead to a similar race condition.  I left that portion of the code
    alone since I feel that the maintainer of the code would have a
    better concept of how he wants to handle errors in that function
    than I do.

1130b656e5 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.

2)	Fixed bug with usermod -d not updating user's home
	directory.
3)	Minor formatting display changes/fixes with *show -P.

d6f907dc7a 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.
