Added a more efficient way to recover the domain of a map.
The extended signature is defined in CMap, and should be compatible
with the old one, except that module arguments have to be explicitely
named. The implementation itself is quite unsafe, as it relies on the
current implementation of OCaml maps, even though that should not be
a problem (it has not changed in ages).
