d34386fef7 perf(frontends/lean/tactic_notation): closes #1345 
We can now elaborate
https://gist.github.com/gebner/439273deee592603190d4f8b4447295b
in 1.6 secs and using less than 500Kb of stack space.
It was takins 44 secs and 5Mb before this commit.

Two modifications:
1) Use pre_monad.seq instead of pre_monad.and_then.
They have the same implementation, but seq is not marked as [inline].

2) Modify how we concatenate the tactics in a begin...end block.
Before: (((a_1 ++ a_2) ++ a_3) ++ a_4)
After:  ((a_1 ++ a_2) ++ (a_3 ++ a_4))

3b38f71f11 fix(library,tests/lean): fix run/interactive tests, and problems in the standard library due to the new interpretation for Type 
We had to change subtype to use Sort since the axiom
strong_indefinite_description uses it.

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

0ba60e62d7 feat(kernel/quotient/quotient): make quotient module robust against users that define their own prelude's 
Before this commit, an user could define their own prelude and change
the types of quot, quot.mk, quot.lift or quot.ind.
By doing that, they could prove false.

This commit prevents this kind of abuse.
It also modifies the definition of `quot` and avoids the `setoid`
dependency.
The previous `quot` type is now called `quotient`, and it is defined
using the new `quot` type provided by the kernel.

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.

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.
