Univs: add Strict Universe Declaration option (on by default)
This option disallows "declare at first use" semantics for universe
variables (in @{}), forcing the declaration of _all_ universes appearing
in a definition when introducing it with syntax Definition/Inductive
foo@{i j k} .. The bound universes at the end of a definition/inductive
must be exactly those ones, no extras allowed currently.
Test-suite files using the old semantics just disable the option.

(* I'm not sure what the general rule should be; intuitively, I want [IsHProp (* Set *) Foo] to mean [IsHProp (* U >= Set *) Foo]. (I think this worked in HoTT/coq, too.) Morally, [IsHProp] has no universe level associated with it distinct from that of its argument, you should never get a universe inconsistency from unifying [IsHProp A] with [IsHProp A].
