After some more checking I discovered that it isn't possible to
"invalidate" a PyCapsule so there is no way to tell if the pointer
inside it is still a valid libpq connection.

The current code (feel free to pull) adds a new method

get_native_connection()

that raise an exception if called on a closed connection. I better like
a method here because it gives the idea that you need to call it every
time you want a Capsule to pass to the target C API.

I also added some docs and a dumb test.

@Daniele, if Christian reports no problems I'll merge this later for 2.8.
