Side-effecting functions creating new universe levels.

Build a fresh instance for a given context, its associated substitution and the instantiated constraints.

Create a fresh global in the environment argument, without side effects. BEWARE: this raises an error on polymorphic constants/inductives: the constraints should be properly added to an evd. See Evd.fresh_global, Evarutil.new_global, and pf_constr_of_global for the proper way to get a fresh copy of a polymorphic global reference.
