This updated version has improved handling of integer types (although I
still don't think it is quite correct wrt signedness for uint32 and
uint64).
The other change is to autogenerate a prototype for each function, this
will hopefully catch cases of parameter mismatch.

tools: ocaml: autogenerate xl datatype definitions and ocaml<->C conversion
The method by which ocaml converts between ocaml types and C
datastructures is based around explicit matching of field indexes
within the ocaml data type to C structure members which is error prone
to write and fragile to maintain (as evidenced by the difference
between the existing hand coded support and the autogenerated code
which shows how out of date the ocaml bindings have
become). Autogenerating these types should reduce these problems.
There is a short list of types which are blacklisted and not
autogenerated because I expect them to change significantly in the
future due to changes to the IDL type (fixing up the TaggedUnion
class).

tools: ocaml: add structure to ocaml stub function definitions
This allows us to generate a C prototype as well and therefore lets the C
compiler catch errors with the stub function implementation.
