feat(library/simplifier): we can "rewrite" with transitive relations
...
The simplifier does not really need the relation to be an equivalence.
Transitivity is the main required property (we need to chain rewrites
together).

feat(frontends/lean/parse_rewrite_tactic): change the semantics of rewrite[↑f] when f is recursive
...
After this commit it behaves like 'unfold f'.
That is, it will unfold f even if it fails to fold recursive
applications. Now, only 'esimp[f]' will not unfold f-applications when
it cannot fold the recursive applications.
This commit also closes #692 . It is part of a series of commits that
addresses this issue.
closes #692

This commit also removes many (now unnecessary) folds from the HoTT
library.
See issue #692
We still have to implement support for recursive definitions based on
brec_on that recurse over inductive families.

See issue #692 .
The implementation still has some rough spots.
It is not clear what the right semantic is.
Moreover, the folds in e_closure could not be eliminated automatically.
