This patch turns internal server addresses to sockaddr_storage to store IPv6 addresses, and makes the connect() function use it. This code already works but some caveats with getaddrinfo/gethostbyname still need to be sorted out while the changes had to be merged at this stage of internal architecture changes. So for now the config parser will not emit an IPv6 address yet so that user experience remains unchanged. This change should have absolutely zero user-visible effect, otherwise it's a bug introduced during the merge, that should be reported ASAP.
