crypt_make_salt to force the crypt method and number of rounds.
* libmisc/salt.c: Add parameter to SHA_salt_rounds to force the
number of rounds.
* libmisc/salt.c, lib/getdef.c: ENCRYPT_METHOD and MD5_CRYPT_ENAB
are needed also when USE_PAM (e.g. for chpasswd).
* src/newusers.c, src/gpasswd.c: Use the new crypt_make_salt prototype.
* src/chpasswd.c, src/chgpasswd.c: Add option -c, --crypt-method
and -s, --sha-rounds to specify the crypt method and number of
rounds in case of one of the SHA methods. The new prototype of
crypt_make_salt simplifies the handling of -m, --md5.
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.

src/faillog.c, src/groups.c, src/chsh.c, src/id.c: Review all the
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.
right place (either 8th, or 11th position).
* NEWS, src/chgpasswd.c, src/chpasswd.c: The protocol + salt does
not need 15 chars. No need for a temporary buffer.
This change the fix committed on 2007-11-10. The salt provided to
pw_encrypt could have been too long.
