4eefc41b6e refactor(*): wrap string in a structure
We want to make sure string users do not depend on the string
implementation. This is the first step.

We need this refactoring *now* to make sure it will not be
super painful to address issue #1175

5cef84709f refactor(library): avoid auxiliary definitions such as add/mul/le/etc
See Section "Other goodies" at
https://github.com/leanprover/lean/wiki/Refactoring-structures

This commit also improves the support for projections in the
unifier/matcher.

Now, we consider the extra case-split for projections.
Given a projection `proj`, and the constraint `proj s =?= proj t`, we need to try first `s =?= t` and if it fails, then try to reduce.
This is needed in the standard library because we now have constraints such as:
```
@has_le.le ?A ?s ?a ?b  =?=  @has_le.le nat nat.has_add x y
```
If we reduce the right hand side, we get the unsolvable constraint
```
@has_le.le ?A ?s ?a ?b  =?=  nat.le x y
```
Before this change, the constraint was `@le ?A ?s ?a ?b  =?=  @le nat nat.has_add x y`, and we already perform a case-split in this case.
Moreover, projections were eagerly reduced whenever possible.
The extra case-split generates a performance problem in several tests. For example `fib 8 = 34` was timing out.
I worked around this issue by performing the case-split only when the constraint contains meta-variables.
There are also minor issues. Example. `<` is notation for `has_lt.lt`, but `>` is for `gt`.
