Uhh, who deallocs a reply port like that :| You can't pass random crap
into __mig_dealloc_reply_port and rely on its particular
implementation, which *happened* to deallocate the current port.

Apparently FATAL_PREPARE in dl-sysdep.h is also defined to do the same.

I'd rather fix these both to do
__mig_dealloc_reply_port (__mig_get_reply_port ());
but we can also explicitly support passing MACH_PORT_NULL to mean
"dealloc whatever you have stored", i.e. the previous behavior.

Which one would you prefer?
