Add -Wused-but-marked-unused as an extra warning flag. 

We can't just turn it on yet, because that would require generators to
know which generated functions use which parameters and mark only the
unused ones as such.  The generator that turns PIDL files into DCE RPC
dissectors is one that would have to be fixed.
