FFI: bugfix: pointer "in" ops must map null to nil.
* ffi.c (ffi_ptr_in_in, ffi_ptr_in_d_in, ffi_ptr_out_in,
ffi_ptr_out_s_in): If the memory location which holds the
pointer to the C object is null, then just return nil.
If we don't do this, we then crash trying to extract
the object from a null pointer via the recursive tgtft->in or
tgtft->get call.
