Begin closing out PR #1519 (this requires a change to chpass too,
and both changes need to be pulled into the stable branch). The
problem here is that when pwd_mkdb creates /etc/passwd, it turns
empty UID and GID fields into zeroes. To fix this, we check the
_PWF_UID and _PWF_GID bits in the pw_fields flag: if the bits
are not set, we print an empty field instead of a zero. This way,
you don't get zeroes in the UID or GID fields unless you explicit
want them.

Implement incremental passwd database updates. This is done by ading a '-u'
option to pwd_mkdb and adding this option to utilities invoking it.
Further, the filling of both the secure and insecure databases has been
merged into one loop giving also a performance improvemnet.
Note that I did *not* change the adduser command. I don't read perl
(it is a write only language anyway).
The change will drastically improve performance for passwd and
friends with large passwd files. Vipw's performance won't change.
In order to do that some kind of diff should be made between the
old and new master.passwd and depending the amount of changes, an
incremental or complete update of the databases should be agreed
upon.

then with a single _PW_KEYYPBYNUM token.

Re-enable +::::::::: wildcards that I had previously disallowed.

Note: if you put +::0:0:::::: in /etc/master.passwd as your only NIS
entry, it will cause all NIS uids and gids to be remapped to zero. This
is *intentional*. That's the way it's supposed to work. Enabling NIS with
no remapping at all is done with +:::::::::, not +::0:0::::::. Similarly,
+:::::::::/bin/csh will remap the shells of all NIS users to /bin/csh.
Or, you could do +wpaul:::::::::/bin/csh to remap NIS user wpaul's shell
to /bin/csh but leave everyone else alone.

- Add support for embedding special entries in the password databases
for +@netgroup/-@netgroup entries. This saves the getpwent functions

- Fix potential bug: when pwd_mkdb writes the YP-enabled flag to the secure
password database, it uses the wrong database descriptor. (It uses the
descriptor from the non-secure database, which is already closed by the time
things are being written into the secure dastabase).

Verify that the username length is smaller than MAXLOGNAME when
asked to verify a passwd file (pwd_mkdb -C).

Entries with oversized usernames are still permitted when building
the passwd database.

When entries are >= MAXLOGNAME in length, they are correctly stored
in passwd, pwd.db and spwd.db but are only correctly retrieved by
getpwent*() and getpwuid*(). getpwnam*() truncates to MAXLOGNAME - 1
when reading from a file (breaking at least sh, tcsh and bash)
and utilities such as su(1) check, complain and fail if the
passed name is >= MAXLOGNAME in length.

Add support for ignoring locking failures. This is only enabled when
you've specified a directory. It is intended to be used in building
custom releases over NFS where locking may be unreliable at best and
there is no contention that the locking is designed to arbitrate.
Other uses of this flag are discouraged. Document same in usage and
man page (including the warning about unwise).
