zeroconf: port to Python 3

Since we're using the source transformer on Python 3, calls into
Zeroconf and return values from it are generally bytes.

But various socket functions require str on Python 3.

This commit contains enough changes to coerce test-paths.t into
passing on Python 3. I suspect there are still a handful of bugs
on Python 3. But the tests do pass.
