The directorin typemaps in the director methods now use std::move on the
input parameter when copying the object from the stack to the heap prior
to the callback into the target language, thereby taking advantage of
move semantics if available.
Add a directorin typemap for SWIGTYPE.
Add director_frob_runme.ml, director_pass_by_value_runme.ml, and
director_unroll_runme.ml.
This commit fixes most of the director-related warnings in the OCaml
test suite. Of the director tests that are currently included in the
OCaml test suite, director_basic and director_property are the only
ones which give warnings (due to issues with typecheck typemaps).
