f133f478c8 Translate correctly between OCaml option values and NULL pointers 
This patch refactors the update_api script and the z3.ml implementation
to properly translate between OCaml options and NULL pointers. Some
unifications and simplifications (avoidance of unnecessary value allocation)
in the script that creates the native bindings.

b85516c271 Fix reference counting in the C layer of the OCaml bindings 
The Z3 context and its reference counters are stored in a structure which is allocated
by the C layer outside the OCaml heap, whenever a Z3 context is created. The structure
and its Z3 context are disposed, once the last reference counter reaches zero. Reference
counters are decremented by C-level finalizers.

The OCaml representations for a Z3 context wrap only a pointer to the corresponding structure.
