When client receives OCC_SERVER_EXIT, it fires SIGUSR1 and switches to
the next server. Next server is defined as same remote with different IP
address if remote resolves into multiple addresses or next remote
otherwise.
This is a client-side only verion of "Notify clients about server's
exit/restart" patch.
