This patch changes the export of `Nothing`/`Cvoid` to JSON `null`.
Methods with `Cvoid` return type will be exported with `"returns": null`
and `Ptr{Cvoid}`, as return type or argument type, will be exported with
`{"kind": "pointer", pointee_type_id": null}`.

Nothingshould not really be treated as any other struct but asCvoid. This patch changes the ABI export ofNothingfromstructtoprimitive.Perhaps it should be it's own kind? The change here made the change for JuliaLibWrapping trivial (JuliaInterop/JuliaLibWrapping.jl#6) but perhaps we can pattern match for a size-0 struct called Nothing over there as an alternative...
