Review Comment:
It is better to directly compare with `==`, but if I really needed address
as an `int`, then
```
int(ffi.cast("intptr_t", p))
```

> Move away from SWIG to CFFI
> ---------------------------
>
> Key: PROTON-2095
> URL: https://issues.apache.org/jira/browse/PROTON-2095
> Project: Qpid Proton
> Issue Type: Wish
> Components: python-binding
> Affects Versions: proton-c-0.29.0, proton-c-future
> Reporter: Omer Katz
> Assignee: Arunagirinadan Sudharshan
> Priority: Major
> Fix For: proton-c-future
>
>
> SWIG is fine but we're not using it for anything other than exporting all of
> proton-c's API as is.
> Unfortunately SWIG only generates CPython extension bindings. This may be a
> problem on PyPy where CPython extensions are either slow or simply won't
> compile.
> Unlike SWIG, CFFI is portable both on CPython and PyPy.
> It also satisfies the same requirements as SWIG currently does.
> In addition, calls to CFFI simply release the GIL which will help
> parallelizing Python applications using threads.
> By using CFFI we can also get rid of all of our setup.py code and simply use
> it to build the extension. We will also no longer have problems building
> wheels.
> The newest version of CFFI supports pkg-config so we can use that to find
> proton-c easily.
> I'm willing to help with the refactor but I'll need a mentor since I'm not
> familiar with the code base.
