d0c2c73b35 refactor(init/meta,tools): rename now tactic to done 
It was pointed out that Coq already uses `now` for a different kind of tactic.
And `done` is more descriptive anyway.

a0a8103804 chore(frontends/lean): go back to 'c' as notation for characters 
This suggestion has been discussed at Slack.
We have decided to use #"c" as notation because we wanted to allow `'`
in the beginning of identifiers like in SML and F*. In particular,
we wanted to allow users to use 'a 'b 'c for naming type parameters
like in SML. However, nobody used this notation. In the Lean standard
library, we are using greek letters for naming type parameters.
So, there is no real motivation for the ugly #"c" syntax.

in the page above.

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`.

cabb4350d9 feat(library): instances are not reducible by default anymore 
Motivation: see "Other goodies" section at
https://github.com/leanprover/lean/wiki/Refactoring-structures

We had to add a new transparency mode: Instances at type_context.
In this mode, instances and reducible definitions are considered
transparent.

The new mode is used in the defeq_canonizer, code generator,
and sizeof lemma generation at inductive_compiler.

We also use the new mode in the unfold tactics.
