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.

0b7859f387 feat(library,frontends/lean): add support for projections in the elaborator
The idea is to simulate the computation rules such as

    pr1 (mk a b) ==> a

in the elaborator

0b57f7d00a refactor(library/tactic): refine interface between tactic and proof-term modes
Some constraints were being lost with the previous interface.
This is why we had a workaround in fintype.lean.

We can also remove some hacks we have used in the past.

matching/unification step.

210cae7d6c fix(library/tactic): we must unfold untrusted macros when type checking intermediate results
Example: before this commit, the file librata/data/list/perm.lean would
not type check if the option -t 0 (trust level zero) was provided.
Reason: the intermediate term contained a macro, and macros are not
allowed at trust level zero.
