584f9e3f49 fix(library/tactic/unfold_rec): support indexed families at unfold_rec
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.

a9515ac7a4 feat(library/tactic/rewrite_tactic): try to fold nested recursive applications after unfolding a recursive function
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.

24762fe843 feat(hit): add hits with 2-path constructors
In hit.two_quotient we define a general construction to define hits with 2-dimensional path constructors, similar to quotients.
We can add 2-paths between any two 'words', where a word consists of 1-path constructors, concatenation and inverses.
We use this to define the torus, reflexive quotients and the reduced suspension.

There is still one 'sorry' in the construction

ff01774fd7 renaming(hit): rename type_quotient to quotient, and quotient to set_quotient
This renaming is because type_quotient is a nonstandard name.  I've had a discussion with Egbert
Rijke, Steve Awodey and Dan Licata, and the consensus for a better name was 'quotient'.  I had to
make changes in src/kernel/hits/hits.cpp, I renamed g_type_quotient* by g_hit_quotient* (to avoid
name clash the standard library quotient, although I don't know whether that name clash would
matter).
