If "Balancer name includes" uppercase letter in name then mod_cluster will not maintain sticky sessions

If one sets ManagerBalancerName (or balancer attribute in m_c subsystem) to something containing an upper case letter, e.g. thisIsBalancerName, sticky sessions behaviour gets broken.

Jean-Frederic suggests looking into usages of strcasecmp() in mod_proxy_balancer, rendering strncmp() in mod_cluster erroneous.
