* NEWS, man/useradd.8.xml: Document the --defaults option, which
was already described in the useradd's Usage information.
Merge RedHat's patch shadow-4.0.18.1-findNewUidOnce.patch:
* src/useradd.c (usr_update): Do not call find_new_uid(). The UID was
already either specified or found by another call to find_new_uid().
* src/useradd.c (find_new_uid): Always start with uid_min (find_new_uid()
is never called when user_id was already specified).
* src/useradd.c (find_new_uid): Fix the comments (find_new_uid() is not
called when the UID is specified (uflg)).
* src/useradd.c (main): Only call find_new_uid() if (!oflg) and (!uflg).
If uflg is set (but not oflg), check the UID uniqueness.
* src/useradd.c (find_new_uid): Don't check the uid and user name
uniqueness in find_new_uid(). The user name uniqueness is already checked
during the parameter validation. UID uniqueness is also checked (see
above).
* src/useradd.c (find_new_uid): Don't check uflg in find_new_uid().
* src/useradd.c (find_new_uid): Make sure that find_new_uid() is not
called when uflg is set (assert).
Cleanups in find_new_gid:
* src/useradd.c (find_new_gid): Check that gflg is not set (assert).

(already checked in main).
* src/useradd.c (find_new_gid): Avoid a "continue" in the loop.
* src/useradd.c (find_new_gid): Remove irrelevant comments.
* src/useradd.c (find_new_gid): Fix the function definition's comment.
libmisc/xgetXXbyYY.c, libmisc/xgetpwnam.c, libmisc/xgetpwuid.c,
libmisc/xgetgrnam.c, libmisc/xgetgrgid.c, libmisc/xgetspnam.c:
Added functions xgetpwnam(), xgetpwuid(), xgetgrnam(),
xgetgrgid(), and xgetspnam(). They allocate memory for the
returned structure and are more robust to successive calls. They
are implemented with the libc's getxxyyy_r() functions if
available.

usage of one of the getpwnam(), getpwuid(), getgrnam(),
getgrgid(), and getspnam() functions. It was noticed on
http://bugs.debian.org/341230 that chfn and chsh use a passwd
structure after calling a pam function, which result in using
information from the passwd structure requested by pam, not the
original one. It is much easier to use the new xget... functions
to avoid these issues. I've checked which call to the original
get... functions could be left (reducing the scope of the
structure if possible), and I've left comments to ease future
reviews (e.g. /* local, no need for xgetpwnam */).
Note: the getpwent/getgrent calls should probably be checked also.
* src/groupdel.c, src/expiry.c: Fix typos in comments.
* src/groupmod.c: Re-indent.
* libmisc/Makefile.am, lib/groupmem.c, lib/groupio.c, lib/pwmem.c,
lib/pwio.c, lib/shadowmem.c, lib/shadowio.c: Move the __<xx>_dup
functions (used by the xget... functions) from the <xx>io.c files
to the new <xx>mem.c files. This avoid linking some utils against
the SELinux library.
