subordinate_parse is supposed to return a static structure that
represents one line in /etc/subuid or /etc/subgid. I goofed and
failed to make the variable rangebuf that holds the username of
in the returned structure static.
Add this missing static specification.

* NEWS: This fix the behavior of groupdel when the system is not
configured to support split group but different group entries
have the name of the group to be deleted.
find_new_uid() and find_new_gid(). They work the same way as the functions
with the same name of useradd or groupadd, except that they check in the
local database to make sure an ID was not reserved in an uncommitted
change (this is needed to be used in newusers), they report a status
instead of calling exit(), and they can receive a preferred ID. They
should later support system IDs. This should be a little bit slower, but
not too much (if the database is not open the checks against the local
database will exit immediately, and if it is already open, all the checks
will be done regarding the data in memory).
Daubert for the patch.
* libmisc/salt.c: Include <stdio.h>, needed for stderr and printf
functions.

skey and md libraries...
* src/Makefile.am: ...Specify for each binary which library is
required. skey and md are required for the binaries with

is required for all. mcrypt is required for user (chfn, chsh,
login, passwd, su, sulogin) and group (newgrp, gpasswd)
authentication and for the creation of passwords (chpasswd,
chgpasswd, gpasswd, newusers, passwd).
SETXXENT_RET, and SETXXENT_TEST. They were used by the now
