This function will invoke the DSO's name_converter callback to translate a
filename, or if the callback isn't set it will instead use the DSO_METHOD's
converter. If "filename" is null, the "filename" in the DSO itself will be
used. If the DSO_FLAG_NO_NAME_TRANSLATION flag is set, then the filename is
simply duplicated. NB: This function is usually called from within a
DSO_METHOD during the processing of a DSO_load() call, and is exposed so that
caller-created DSO_METHODs can do the same thing. A non-null return value
will need to be free()'d.
