George Bosilca 5390fd6f33 Reshape the datatype engine. The basic types are built down in OPAL. MPI types are
either direct link to these basic predefined types, or a combination of them.
Anyway, the first items in the datatype list belong to OPAL, the second round
are MPI datatypes created by composing basic OPAL datatypes, and the last
batch are mapped datatype (direct correspondance between an OMPI datatype and
an OPAL one such as int -> int32_t).

Modify the op to fit this new scheme.
