Summary of changes : - 'maxconn' server parameter to do per-server session limitation - queueing to support non-blocking session limitation - fixed removal of cookies for cookie-less servers such as backup servers - two separate wait queues for expirable and non-expirable tasks provide better performance with lots of sessions. - some code cleanups and performance improvements - made state dumps a bit more verbose - fixed missing checks for NULL srv in dispatch mode - load balancing on backup servers was not possible in source hash mode. - two session flags shared the same bit, but fortunately they were not compatible.
