Subject: Finish fix for the treatment of [inverse] in [setoid_rewrite], making
 a variant of the [unify] tactic that takes a hint db as argument and does
 unification modulo its [transparent_state]. Add test-file for bug #1939 and
 another [AdvancedTypeClasses.v] that mimicks [AdvancedCanonicalStructure.v].
