lib/util/safe_string.h is similar to source3/include/safe_string.h, but
the former has fewer checks. It is missing bcopy, strcasecmp, and
strncasecmp.
Add the missing elements to lib/util/safe_string.h remove the other
safe_string.h which is in the source3-specific path. To accomodate
existing uses of str(n?)casecmp, add #undef lines to source files where
they are used.

The salt stored by Windows in the package_PrimaryKerberosBlob
(within supplementalCredentials) seems to be
'W4EDOM-L4.BASEkrbtgtBLA' for the above trust
and Samba stores 'W4EDOM-L4.BASEBLA$'.
While the salt used when building the keys from
trustAuthOutgoing/trustAuthIncoming is
'W4EDOM-L4.BASEkrbtgtBLA.BASE', which we handle correct.
