If ngIRCd is compiled to register its services using ZeroConf (e.g. using Howl, Avahi or on Mac OS X) this parameter can be used to disable service registration at runtime.

... because it must be included in the distribution archive :-)

This fixes the following gcc compiler warning: tool.c: In function 'ngt_SyslogFacilityName': tool.c:195: warning: return discards qualifiers from pointer target type

The new option "SyslogFacility" deines the syslog "facility" to which ngIRCd should send log messages. Possible values are system dependant, but most probably "auth", "daemon", "user" and "local1" through "local7" are possible values; see syslog(3). Default is "local5" for historical reasons.

These both functions translate syslog facility names to ID numbers and vice versa. On systems that don't define the facilitynames[] array in syslog.h, we try to build one ourself.

This fixes the following gcc warning, emitted by Xcode: src/ngircd/sighandlers.c: In function 'Signal_Callback': src/ngircd/sighandlers.c:239: warning: implicit conversion shortens 64-bit value into a 32-bit value

And update static Mac OS X config.h used by the Xcode project.

Signals_Init() must only be called once. This does not affect any ngircd release version. Earlier version of this patch moved the io and sighandler initialization before the while() loop, but as Alexander Barton noticed that broke all systems without builtin select support in io.c...

- declare signals_catch[] array not between the function implementations. - rename now local function NGIRCd_Rehash() to Rehash(). - remove empty and therefore not used "catch SIGHUP; break;".

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.

now that the main signal handling is done from the dispatcher loop we can call NGIRCD_Rehash() directly. the /REHASH handler can queue the Rehash() function for execution by sending a SIGHUP. It will be run when we return back to the dispatch loop.

Allows to defer/queue signal processing for execution on the next event dispatch call, i.e. we can perform any signal action in normal, non-signal context. Example uses: - Reload everything on HUP without writing a global "SIGHUP_received" variable - Dump status of internal Lists on SIGUSR1, etc.
