84188c5aa1 feat(frontends/lean/elaborator): add pattern validator in the elaborator 
@johoelzl We now produce a better message for your example:

   inductive R : ℕ → Prop
   | pos : ∀p n, R (p + n)

   lemma R_id : ∀n, R n → R n
   | (.p + .n) (R.pos p n) := R.pos p n

The new error is:

file.lean:5:2: error: invalid function application in pattern, it cannot be reduced to a constructor (possible solution, mark term as inaccessible using '.( )')
  .p + .n

6d9c9b3f9a feat(library/type_context): avoid auxiliary definitions introduced by the equation compiler from being used in the type class resolution procedure 
This can only happen in meta definitions, but the user may be confused
by this behavior.

ab94e71e37 feat(library/type_context): do not fail on universe constraints of the form ?u =?= max ?u v 
We solve them by creating a fresh metavariable ?w

         ?u := max ?w v

Remark: this is a precise solution.

b2968f450c fix(frontends/lean/elaborator): use expected type when elaborating application for the form (c^.fn a) 
For example, the following definition did not work before this commit:

  protected meta def map {α β} (f : α → β) : lazy_tactic α → lazy_tactic β
  | t s := (t s)^.for (λ ⟨a, new_s⟩, (f a, new_s))

d315e424ff feat(library/congr_lemma, library/fun_info): make sure opt_param gadget do not confuse the simplifier, fun_info, congr_lemma, etc 
A definition such as

  def f (a : nat) (b : nat := a) (c : nat := a) :=
  a + b + c

should *not* be treated as a dependent function.

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))

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

2c3f6d0e1c fix(frontends/lean/structure_cmd): default field values of Pi type 
There were two separate issues:
* An explicit Pi as the type of a field with a default value would be considered a field reference
* An implicit Pi would be instantiated by the elaborator during `visit_structure_instance`
