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.

f650a1b873 refactor(library/init/meta): avoid '_core' idiom using default parameters 
I kept a few core methods (e.g., exact_core and apply_core). Reason:
if we use default parameters

    meta constant exact (e : expr) (md := semireducible) : tactic unit

then, we will not be able to write

    to_expr p >>= exact

The workaround is

    do t <- to_expr p, exact t

or
    to_expr p >>= (fun x, exact x)

One alternative is to change how we handle default parameters, and
eta-expand applications that involve default parameters.
We may also have an attribute [eta_expand]. Then

    attribute [eta_expand] foo

instructs the elaborator to automatically eta-expand foo-applications.
The attribute would give users more control, and avoid potential
performance problems. Without the attribute, then for every function
application the elaborator has to check the type and decide whether it
must be eta-expanded or not.

@gebner @kha What do you think?

cce88c6190 refactor(frontends/lean): interactive tactic support 
After this commit, new interactice tactic classes can be added without
writing C++ code (see example: tests/lean/run/my_tac_class.lean).

The tactic_evaluator was simplified, and all the complexity has been
moved to tactic_notation, and lean code.

We can now inspect the intermediate states produced by the rewrite
tactic.

The function (@scope_trace _ line col thunk) can be used to position trace
messages produced by thunk. If line/col are not provided (i.e., we
just write (scope_trace thunk)), then line/col are filled with the
position of this term by the elaborator.

We can visualize the intermediate tactic states inside nested blocks
such as (try { ... })

The new infrastructure can be used to implement custom tactic_state
pretty printers.
