Convert between Prefix:Local and full IRI (an atom). If IRISpec is
an atom, it is simply unified with IRI. This predicate fails
silently if IRI is an RDF literal.
Note that this predicate is a meta-predicate on its output argument.
This is necessary to get the module context while the first argument
may be of the form (:)/2. The above mode description is correct, but
should be interpreted as (?,?).

- - Error handling is incomplete. In its current implementation
the same code is used for compile-time expansion and to
facilitate runtime conversion and checking. These use cases
have different requirements.
