    so plug-ins cannot thaw what they haven't frozen, and the code
    can clean up frozen stuff left behind by crashed or broken plug-ins.
    
    Also redo the cleanup code so it only keeps track of the undo group
    counts and freeze counts of what *this* GimpPlugInProcFrame did
    itself. That should make it even stricter against broken code that
    could mess up internals.
