Enable the daemon to dump its internal state in debug-mode.

This patch allows ngIRCd to dump its internal state (connected clients,
actual configuration) when compiled with --enable-debug. The daemon
catches two more signals:

 - SIGUSR1: toggle debug mode (on/off),
 - SIGUSR2: dump internal state to console/syslog.
