OPTIM: server: switch the actconn list to an mt-list The remaining contention on the server lock solely comes from sess_change_server() which takes the lock to add and remove a stream from the server's actconn list. This is both expensive and pointless since we have mt-lists, and this list is only used by the CLI's "shutdown server sessions" command! Let's migrate to an mt-list and remove the need for this costly lock. By doing so, the request rate increased by ~1.8%.
