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

16b7bc3922 fix(kernel/default_converter): broken optimization 
we must also check the universe levels when applying the optimization for
constraints of the form:

            f.{l_1 ... l_k} a_1 ... a_n  =?= f.{l_1' ... l_k'} b_1 ... b_n

The optimization tries to avoid unfolding f if we can establish that
a_i is definitionally equal to b_i for each i in [1, n]

cd17618f4a refactor(library): replace 'calc_trans', 'calc_symm', 'calc_refl' and 'calc_subst' commands with attributes '[symm]', '[refl]', '[trans]' and '[subst]' 
These attributes are used by the calc command.
They will also be used by tactics such as 'reflexivity', 'symmetry' and
'transitivity'.
