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.

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`

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.

2ca2920284 fix(library/tactic/simplify): relax test 
We only need to check whether the resulting expression does not contain
temporary metavariables introduced by the simplifier.
It is ok if it contains regular metavariables that were already in the goal.
