This can be returned from NetApp Ontap 7.3.7 SMB server
implementations. Now we have ensured smb2_signing_check_pdu()
cannot return NT_STATUS_INVALID_PARAMETER on a signing error
it's safe to check this error code here. Windows 10
clients ignore this error from the NetApp.

It's good to have just a single isolated function that will generate
random challenges, in future we can add some logic in order to
avoid weak values, which are likely to be rejected by a server.

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.
