It looks like we're passing NULL values to ep_strdup_printf() in
dissect_ldap_SubstringFilter(). This isn't a big deal on Linux or OS X, but it
causes a crash on Windows.

It might be useful to have a utility function that, when passed a char *,
returns the pointer if it's non-null and "[null]" if it is null. It would
simplify a lot of code in the LDAP dissector and in other dissectors as well.
