This patch implements ability to set the current state of one server by tracking another one. It: - adds two variables: *tracknext, *tracked to struct server - implements findserver(), similar to findproxy() - adds "track" keyword accepting both "proxy/server" and "server" (assuming current proxy) - verifies if both checks and tracking is not enabled at the same time - changes set_server_down() to notify tracking server - creates set_server_up(), set_server_disabled(), set_server_enabled() by moving the code from process_chk() and adding notifications - changes stats to show a name of tracked server instead of Chk/Dwn/Dwntime(html) or by adding new variable (csv) Changes from the previuos version: - it is possibile to track independently of the declaration order - one extra comma bug is fixed - new condition to check if there is no disable-on-404 inconsistency
