Irccd: rework server to be simpler

Server no longer has signals, now user is responsible of calling connect(),
recv() and pass a completion handler. The recv function will complete with a
std::variant of all possible events.

The server does not manage itself anymore, the reconnection system has been
moved to server_service instead.

To simplify reconnection, the limit has been removed now you can only enable
indefinite reconnection or disable it at all.

closes #892

 #### Module System
 
   - The function `Irccd.System.name` has now well defined return value.
+
+### Irccd
+
+#### Configuration
+
+- The option `reconnect-tries` has been removed from `[server]` section, use
+  `auto-reconnect` boolean option instead.
+- The option `reconnect-timeout` has been renamed to `auto-reconnect-delay`.
