Previously all callers had a containing object with a destructor that could be used to trigger cleanup of the IORange objects (typically just freeing the containing object), but a forthcoming memory API change doesn't fit this pattern. Rather than setting up a new global table, extend the ioport system to support destructors. Signed-off-by: Avi Kivity <avi@redhat.com>
