    convert_glib.m4: Remove _CONVERSIONs that can cause memory leaks
    
    Converting from a non-const gchar* to Glib::ustring or std::string without
    calling g_free() has caused memory leaks in several signals and vfuncs.
    Remove these conversions from convert_glib.m4. Correct conversions can be
    added in .hg files where they are needed, and where it's known what is correct.
