c5fb3ec6d0 fix(library/definitional/equations): fixes #541
This commit allows recursive applications to have less or more arguments
than the equation left-hand-side.
We add two tests
   - 541a.lean  recursive call with more arguments
   - 542b.lean  recursive call with less arguments

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.

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.
