Subject: Fix race condition triggered by fresh universe generation

Remote counters were trying to build universe levels (as opposed to
simple integers), but did not have access to the right dirpath at
construction time. We fix it by constructing the level only at use time,
and we introduce some abstractions for qualified and unqualified level
names.

Subject: Revise API for global universes.

Rename Univ.Level.{Qualid -> UGlobal}, remove Univ.Level.Id.

Remove the ability to split the argument of `Univ.Level.Level` into a
dirpath*int pair (except by going through string hacks like
detyping/pretyping(/funind) does).

Id.of_string_soft to turn unnamed universes into qualid is pushed up
to detyping. (TODO some followup PR clean up more)

This makes it pointless to have an opaque type for ints in
Univ.Level: it would only be used as argument to
Univ.Level.UGlobal.make, ie
~~~
open Univ.Level
let x = UGlobal.make dp (Id.make n)
(* vs *)
let x = UGlobal.make dp n
~~~

Remaining places which create levels from ints are various hacks (eg
the dummy in inductive.ml, the Type.n universes in ugraph
sort_universes) and univgen.

UnivGen does have an opaque type for ints used as univ ids since they
get manipulated by the stm.

NB: build breaks due to ocamldep issue if UGlobal is named Global instead.
