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.

This was just a wrapper around resolve_name_ex(), so just call that
instead.

By going via these tevent functions, we avoid needing to dereference
the struct socket_address, which may contain a 'struct sockaddr' or
strings.  The new dns_host_file resolver returns in the form of a
struct sockaddr.

We were creating the name resolution context as a child of lp_ctx,
which meant when we gave up on a connection the timer on name
resolution kept running, and when it timed out the callback crashed as
the socket was already removed.
