e2df287aad Don't redefine errno(3)
It is Undefined Behavior to declare errno (see NOTES in its manual page).
Instead of using the errno dummy declaration, use one that doesn't need
a comment.

4d606cc690 * configure.in: New configure option: --with-sha-crypt enabled by
default. Keeping the feature enabled is safe. Disabling it permits
  to disable the references to the SHA256 and SHA512 password
  encryption algorithms from the usage help and manuals (in addition
  to the support for these algorithms in the code).
* libmisc/obscure.c, libmisc/salt.c, src/newusers.c,
  src/chpasswd.c, src/chgpasswd.c, src/passwd.c: ENCRYPT_METHOD is
  always supported in login.defs. Remove the ENCRYPTMETHOD_SELECT
  preprocessor condition.
* libmisc/obscure.c, libmisc/salt.c, src/newusers.c,
  src/chpasswd.c, src/chgpasswd.c, src/passwd.c: Disable SHA256 and
  SHA512 if USE_SHA_CRYPT is not defined (this corresponds to a
  subset of the ENCRYPTMETHOD_SELECT sections).

9aa40bb96d * libmisc/obscure.c, libmisc/salt.c, src/passwd.c: Match DES, MD5,
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.

b8d8d0de00 Add support for SHA256 and SHA512 encrypt methods. Apply RedHat's patch
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.
