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.

fdadada3a9 fix(frontends/lean): fixes #1468 
@kha I had to add yet another hack to fix this issue.

In notation declarations, names are resolved at notation declaration time.
So, users do not expect them to be resolved again at tactic execution time.

I addressed this problem by wrapping constants occurring in notation
declarations with a "frozen_name" annotation. This transformation is
only performed if m_in_quote is true.
Then resolve_names_fn at elaborator.cpp will not try to resolve the
names again.

This change broke two other modules. `-` notation for inverting
equations at `rw`, and `calc` expressions inside quotes.
The broke for the same reason. They were not expecting the constants
to be wrapped with an annotation.

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.

cd17618f4a refactor(library): replace 'calc_trans', 'calc_symm', 'calc_refl' and 'calc_subst' commands with attributes '[symm]', '[refl]', '[trans]' and '[subst]' 
These attributes are used by the calc command.
They will also be used by tactics such as 'reflexivity', 'symmetry' and
'transitivity'.

See issue #500

4ec0e1b07c feat(frontends/lean): improve calc mode 
Now, it automatically supports transitivity of the form
    (R a b) -> (b = c) -> R a c
    (a = b) -> (R b c) -> R a c

bc65aeb5e1 fix(frontends/lean/calc): add expected type for single-step calc expressions, fixes #357 
This is not an issue for calc expressions containing multiple steps,
since the transitivity step will "force" the expected type for the proofs.

94cf10284a fix(frontends/lean/calc_proof_elaborator): bug when inserting symmetry proofs for heq, fixes #286 
The problem was that heq type is
    Pi {A : Type} (a : A) {B : Type} (b : B), Prop

The calc_proof_elaborator was assuming that (a : A) (b : B) were the
last two arguments in any relation supported by calc.

The fix is to remove this assumption.

407e35692b feat(frontends/lean/calc): wrap calc proofs with 'proof-qed' annotation to identify places where proof influences what is being proved 
Later, we will add a custom annotation and elaborator for calc proofs.
This is the first step for issue #268.

Remark: we don't wrap the proof if it is of the form

   - `by tactic`
   - `begin tactic-seq end`
   - `{ expr }`
