Here is new version of the patch. Now I've reworked hostorder=random and
it seems to work as well as sequential. failover_timeout works too.
I've also found a case when attempt to connect fail when receiving
FATAL message from server which is not properly up yet. So, it is fixed
too.
Addititonally, error messages from all failed connect attempts are not
accumulated now. Only last one is returned.
