335c58f8a7 feat(kernel): add expr_kind::Quote 
This is a temporary expr constructor. We need it to be able to eliminate
expr_macro, and then define expr using runtime/object

62788a9ca3 refactor(kernel): fix terminology: "free_var" is actually a loose bound variable 
We represent free variables uisng local constants.
We will fix this terminology too.

0556412f8d refactor(*): add runtime folder 
@kha The runtime folder includes what is needed to link a
standalone Lean program. It is still contains some unnecessary files.
We will be able to remove them after we release Lean4.

d0d75c0923 refactor(kernel): reduce number of configurations supported in the kernel 
Now, eta and impredicativity are assumed to be always true.

Motivation: the rest of the system assumes eta.
Regarding impredicativity, we decided to support only the standard library.

d8079aa16a refactor(library): create copy of the kernel type_checker in library 
Motivation: it will allow us to simplify the kernel type_checker and
make sure it implements the same API provided by type_context

3c878ecd01 feat(kernel): add let-expressions to the kernel 
The frontend is still using the old "let-expression macros".
We will use the new let-expressions to implement the new tactic framework.

f177082c3b refactor(*): normalize metaclass names 
@avigad and @fpvandoorn, I changed the metaclasses names. They
were not uniform:
- The plural was used in some cases (e.g., [coercions]).
- In other cases a cryptic name was used (e.g., [brs]).

Now, I tried to use the attribute name as the metaclass name whenever
possible. For example, we write

   definition foo [coercion] ...
   definition bla [forward] ...

and

  open [coercion] nat
  open [forward] nat

It is easier to remember and is uniform.

8b7dc4e03a feat(frontends/lean): apply eta-reduction in postprocessing step 
Perhaps, we should add an option to disable this new feature.

Remark: this commit makes commit 46d418a redundant.
I'm keeping 46d418a because we may retract this commit in the future.
