Add a boolean to indicate the unfolding state of a primitive projection,
so as to reproduce correctly the reduction behavior of existing
projections, i.e. delta + iota. Make [projection] an abstract datatype
in Names.ml, most of the patch is about using that abstraction.
Fix unification.ml which tried canonical projections too early in
presence of primitive projections.
