Allow declaring universe constraints at definition level.
Introduce a "+" modifier for universe and constraint declarations to
indicate that these can be extended in the final definition/proof. By
default [Definition f] is equivalent to [Definition f@{+|+}], i.e
universes can be introduced and constraints as well. For [f@{}] or
[f@{i j}], the constraints can be extended, no universe introduced, to
maintain compatibility with existing developments. Use [f@{i j | }] to
indicate that no constraint (nor universe) can be introduced. These
kind of definitions could benefit from asynchronous processing.
Declarations of universe binders and constraints also works for
monomorphic definitions.
