bf9f7560f7 feat(frontends/lean): (Type u) can't be a proposition 
(Type u)  is the old (Type (u+1))
(PType u) is the old (Type u)
Type*     is the old (Type (_+1))
PType*    is the old Type*

The stdlib can be compiled, but we still have > 70 broken tests

cce88c6190 refactor(frontends/lean): interactive tactic support 
After this commit, new interactice tactic classes can be added without
writing C++ code (see example: tests/lean/run/my_tac_class.lean).

The tactic_evaluator was simplified, and all the complexity has been
moved to tactic_notation, and lean code.

We can now inspect the intermediate states produced by the rewrite
tactic.

The function (@scope_trace _ line col thunk) can be used to position trace
messages produced by thunk. If line/col are not provided (i.e., we
just write (scope_trace thunk)), then line/col are filled with the
position of this term by the elaborator.

We can visualize the intermediate tactic states inside nested blocks
such as (try { ... })

The new infrastructure can be used to implement custom tactic_state
pretty printers.

0795acaf6a refactor(library/init/algebra): new transport from multiplicative to additive 
The motivation is to avoid the problems produced by the "declare as
structure and then tag as class idiom" described in the file ring.lean.

694e6f47dc fix(library/init/meta/smt/ematch,library/tactic/simp_lemmas): trick for adding equations of a definition to a simp/hinst lemma set 
Before this commit, if we declared an equational lemma using 'def',
then it would not be correctly added to the simp/hinst lemma set.
The new test exposes the problem.
