About building of substitutions from instances.
Redefining adjust_subst_to_rel_context from instantiate_context who
was hidden in inductiveops.ml, renamed the latter into
subst_of_rel_context_instance and moving them to Vars. The new name
highlights that the input is an instance (as for applist) and the
output a substitution (as for substl). This is a clearer unified
interface, centralizing the difficult de-Bruijn job in one place. It
saves a couple of List.rev.
