feat(frontends/lean/elaborator): coercion from (decidable) Prop to bool
...
This is a hard coded extra case. It is not an instance of has_coe.
Even if we change has_coe to accomodate this case, it will not be a
satisfactory solution because this coercion depends on the element and
not the type, and the element usually contains metavariables.
We should eventually write a tactic for synthesizing coercions.

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?

fix(frontends/lean, library/tactic): remove redundant error messages, and fix position of error messages
...
Summary:
We minimize the number of "'sorry' used warning messages". We also
re-target the error to the main declaration. Example: foo._main ==> foo
We do not report for auxiliary declarations such as "_example" and
"foo.equations._eqn_1"
Get rid of the redundant error message "error : failed" for tactics.
We added "silent failures" in the tactic framework.
We do not store line/col information for tactics nested in notation
declarations. Before this commit, we would have tactics such
as (tactic.save_info line col) nested inside of notation declarations.
