Support resolving multiple IP addresses

Description

Currently, twisted doesn't support resolving multiple IP addresses for a host name. This patch fixes that by adding an extended option to getHostByName, returning the same value as python's standard socket.gethostbyname_ex. It would be good to support this in the non blocking (non threaded) client too, in twisted.names.client.

I think that getaddrinfo is how we'll do this. See #4362.

Cool idea, but if one needs to resolve multiple addresses *now*, what would you recommend? :)

You can call socket.getaddrinfo yourself (in a thread) or use the non-threaded asynchronous APIs provided by twisted.names.client.
