Bugfixes

• IPv6 support on Windows was broken due to missing constants in the socket
  module. This has been resolved by setting the constants on Windows if they
  are missing. See socket.IPPROTO_IPV6 undefined in Python 2.7.12 for Windows Pylons/waitress#138

• A ValueError was raised on Windows when passing a string for the port, on
  Windows in Python 2 using service names instead of port numbers doesn't work
  with getaddrinfo. This has been resolved by attempting to convert the port
  number to an integer, if that fails a ValueError will be raised. See
  Invalid host/port specified error on Windows Pylons/waitress#139
