Update to 2.006:

2.006 2014/11/22
- Make (hopefully) non-blocking work on windows by using EWOULDBLOCK instead of
  EAGAIN. While this is the same on UNIX it is different on Windows and socket
  operations return there (WSA)EWOULDBLOCK and not EAGAIN. Enable non-blocking
  tests on Windows too.
- make PublicSuffix::_default_data thread safe
- update PublicSuffix with latest list from publicsuffix.org
