MINOR: cli: create new function cli_has_level() to validate permissions This function is used to check that the CLI features the appropriate level of permissions or to prepare the adequate error message.

MEDIUM: mworker: stop the master proxy in the workers The master proxy which handles the CLI should not be used or shown in the stats of the workers. This proxy is now disabled after the fork.

/* mworker proxy functions */
MEDIUM: mworker: proxy for the master CLI This patch implements a listen proxy within the master. It uses the sockpair of all the workers as servers. In the current state of the code, the proxy is only doing round robin on the CLI of the workers. A CLI mode will be needed to know to which CLI send the requests.

int mworker_cli_proxy_create();
MEDIUM: mworker: create CLI listeners from argv[] This patch introduces mworker_cli_proxy_new_listener() which allows the creation of new listeners for the CLI proxy. Using this function it is possible to create new listeners from the program arguments with -Sa <unix_socket>. It is allowed to create multiple listeners with several -Sa.

int mworker_cli_proxy_new_listener(char *line);
MEDIUM: mworker: each worker socketpair is a CLI listener The init code of the mworker_proc structs has been moved before the init of the listeners. Each socketpair is now connected to a CLI within the workers, which allows the master to access their CLI. The inherited flag of the worker side socketpair is removed so the socket can be closed in the master.

MEDIUM: cli: implement 'mode cli' proxy analyzers 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.
