Use the generic function type void (*) (void *) for all unwind
cleanups.  When an existing cleanup doesn't already have that
type, change the type if the function is used only as a cleanup,
and add a shim function otherwise.  If the shim is used in more
than one compilation unit, put the shim function next to the
cleanup as an extern function; otherwise, put the shim in the
compilation unit as a static function.

Thanks, this looks great. I hadn't started on the unwind-protect code.
It's one of the oldest parts of the code base.
