Looking at backover.c code, it appears that overlays at bi_db_open are
passed the __real__ backend structure; so my proposal to have a "real"
be_controls array in the backend structure which is a copy of the
bi_controls + overlays and in general run-time modules augmentation looks
feasible. Unless there's a better way, I'd start code it (so I can test
my overlay :)
