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.

f7edf601c8 fix(library/init/data/nat/lemmas): avoid bad patterns in nat sub ematch lemmas 
The attribute [ematch_lhs] instructs Lean to use the left-hand-side of
the conclusion as a pattern.

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.

1726d37d4e fix(library/algebra/order): decidable_linear_order 
Add fields for decidable_eq and decidable_le.
We need this because a concrete instance may have its own
implementation that is not definitionally equal to
the old ones defined at library/algebra/order.lean.
Without this change, types such as nat and int would
have multiple definitions for decidable_eq and decidable_le
which are not definitionally equal.
