Log message:

Implement a mechanism for servers to indicate to the network that they are
hubs, servers, or both.  We take parv[7], an unspecified unsigned int in
previous versions, and turn it into a mode-like string--it's not actually a
mode in the /mode #channel sense, but it looks similar.  This works in
conjunction with two new flags, FLAGS_HUB and FLAGS_SERVICE.  There is
currently no user-visible impact of this change.
