232054c09b lib/util: remove extra safe_string.h file
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.

05bc4de083 Revert making public of the samba-module library.
This library was tiny - containing just two public functions than were
themselves trivial. The amount of overhead this causes isn't really worth the
benefits of sharing the code with other projects like OpenChange. In addition, this code
isn't really generically useful anyway, as it can only load from the module path
set for Samba at configure time.

Adding a new library was breaking the API/ABI anyway, so OpenChange had to be
updated to cope with the new situation one way or another. I've added a simpler
(compatible) routine for loading modules to OpenChange, which is less than 100 lines of code.
