microseconds to avoid having the same salt for different passwords
generated in the same second. This permits to avoid using the same salt
for different passwords in newusers.
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).

closed after during a copy.
default. Keeping the feature enabled is safe. Disabling it permits
to disable the references to the SHA256 and SHA512 password

to the support for these algorithms in the code).
* libmisc/obscure.c, libmisc/salt.c, src/newusers.c,

* libmisc/Makefile.am, libmisc/getlong.c, src/chgpasswd.c,
src/chpasswd.c: New getlong function. Replace chpasswd's and
chgpasswd's getnumber.
SHA256, and SHA512 exactly (not only the first 3/6 chars).
* libmisc/salt.c (SHA_salt_rounds): Set rounds to the specified
prefered_rounds value, if specified.
* src/gpasswd.c, libmisc/salt.c: Fix compilation warnings (use
size_t for lengths).
* src/chpasswd.c, src/chgpasswd.c: Add missing parenthesis.
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.
bytes).
* lib/getdef.c, etc/login.defs: Add definitions for
SHA_CRYPT_MIN_ROUNDS and SHA_CRYPT_MAX_ROUNDS.
* libmisc/salt.c: Use SHA_CRYPT_MIN_ROUNDS and SHA_CRYPT_MAX_ROUNDS
to add a random number of rounds if needed.

* libmisc/salt.c (crypt_make_salt): Initialize result[0] to nul at
the beginning (was not initialized when USE_PAM).
* libmisc/salt.c (crypt_make_salt): Check that ENCRYPT_METHOD is a
valid crypt method.
shadow-4.0.18.1-sha256.patch. Thanks to Peter Vrabec. Hardly no changes
except re-indent and changes related to recent modifications (max_salt_len
in crypt_make_salt). Changes in lib/defines.h not applied (definition of
ENCRYPTMETHOD_SELECT). I will add a configure check or flag.
