77c20e99ff feat(library/tactic/inversion_tactic): consistent orientation of generated equalities 
Generated equalities in proof irrelevant environments were inverted
compared with the documentation and the proof relevant case, which
resulted in newly generated local vars replacing equivalent old ones
instead of the other way around.

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.

'transitivity'.
