python CFFI bindings integration into notmuch build/test

[Floris Bruynooghe]

Hi,

Thanks for carrying on with this!

I'm a little confused with how to follow this, is the current state of
the code somewhere in a repo/branch where I can try things out and make
changes from?

I'd have gone with what David wrote to be fair, mostly because it's
pretty simple to see what's going on where for the preexec_fn I'd have
to look at the docs.  Not sure if this has much to do with Python style
though, more with how much you like Unix tricks.
