Return _ZRealm_server from get_realm_lists()

Instead of returning an array of server hostname strings for each realm,
get_realm_lists() now returns an array of struct _ZRealm_server for each
realm.  This allows it to return additional per-server information found
in the realm.list file, such as the nosend flag, and simplifies creation
of the final per-realm server list.

This change will make it easier to use interned strings for server names,
which will eventually enable efficient processing of updates to server
configuration when the realm.list file is reloaded.
