More Python 3 fixes

* Port set_multi() to Python 3
* Port delete_multi() to Python 3
* Fix _get_server() on Python 3 when the connection to the first server
  fails: encode to ASCII before calling serverHashFunction.
* Fix expect(): don't decode line on Python 3, return the raw line
* Add more unit tests
* tox now also runs unit tests
* Explicit the encoding when calling str.encode(): use 'utf-8'
* test_memcache: close sockets in tearDown()
* test_get_unknown_value(): delete the key to ensure that it doesn't exist
