This patch implements analysers for parsing the CLI and extra features for the master's CLI. For each command (sent alone, or separated by ; or \n) the request analyser will determine to which server it should send the request. The 'mode cli' proxy is able to parse a prefix for each command which is used to select the apropriate server. The prefix start by @ and is followed by "master", the PID preceded by ! or the relative PID. (e.g. @master, @1, @!1234). The servers are not round-robined anymore. The command is sent with a SHUTW which force the server to close the connection after sending its response. However the proxy allows a keepalive connection on the client side and does not close. The response analyser does not do much stuff, it only reinits the connection when it received a close from the server, and forward the response. It does not analyze the response data. The only guarantee of the end of the response is the close of the server, we can't rely on the double \n since it's not send by every command. This could be reimplemented later as a filter.
