[tor-commits] [stem/master] Allow control connection to IPv6 addresses

[atagar@xxxxxxxxxxxxxx]

commit 1087ebf6dadad2cc3ee81ad5ba8dc35e327cb665

    Allow control connection to IPv6 addresses
    
    Controller.from_port() improperly rejects IPv6 addresses as invalid...
    
      https://github.com/torproject/stem/issues/74
    
    This expands a few other methods to allow IPv6 addresses as well.
