retrieve_obligations env id sigma fs ?status body type returns obls, (evnames, evmap), nbody, ntype a list of obligations built from evars in body, type.

fs is the number of function prototypes to try to clear from evars contexts. evnames, evmap) is the list of names / substitution functions used to program with holes. This is not used in Coq, but in the equations plugin; [evnames] is actually redundant with the information contained in [obls]
