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.
