d775ee98b4 feat(frontends/lean): auto_param support at structure_instance, and better error messages 
Summary:

- A field value was being elaborated more than once when there is
  another field whose default value depends on it.
  The new test `structure_default_value_issue.lean` exposes the problem.

- Better error message and localization at field type mismatches.
  When there is field type mismatch, the error message contains the
  field name, and the error is reported at the field position instead of
  `{`.

- We add support for auto_param at structure instances `{...}`
  See #1422

0c6108ce7a chore(library/init/data/quot): use Sort instead of Type 
Remark: The kernel was already using Sort. So, the limitation was
artificial. Moreover, it may seem unnecessary to have quotients of
proofs in a proof irrelevant system, but this is useful for proving
a more general funext lemma. This more general version is needed in
the new tested contributed by @digama0.

525242561a fix(library/init/meta/tactic): use zeta reduction by default in the abstract tactic 
Abstracting let-exprs may produce type errors.
In the future we may consider another strategy for `abstract`.
First, we try to abstract the `let`, then if it fails, we expand.
Not sure if this is a good idea.

17556758cb feat(library/constructions,library/inductive_compiler): automatically generate dependent eliminator for inductive predicates 
The dependent eliminator for an inductive predicate C is called C.drec

TODO: construct dcases_on and drec_on using C.drec

We need this recursor for implementing dependent elimination for
inductive predicates.

We don't need to define acc.drec and eq.drec in the standard library anymore.
