7551d83c35 various: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

9e66c6e8f0 Speed up pw operations that edit /etc/group or /etc/passwd
r285050 fixed a bug in pw that could lead to /etc/passwd or /etc/group
corruption on power loss. However, it fixed it by opening those files with
O_SYNC, which is very slow, especially on ZFS. This change replaces O_SYNC
with appropriately placed fsync()s instead, which is much faster. Using a
ZFS tmpdir, the time to run pw's kyua tests drops from 245s to 35s.

b9e2a3df4b Unbreak group operations by reverting previous delta which removed the
assignment of `l' in `gr_update' to the return value of snprintf.  It
claimed to have fixed the case where snprintf returned -1--in fact, it
broke the entire routine.  Not setting `l' here causes fileupdate() to
invariably fail with EINVAL because it does its own check to assert
that the parameter isn't -1.

7f7ff280d1 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]

aea1f6bc3c 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.

808a36ef65 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.

4a198ee0cb 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.
