* $Log: client.c,v $
+ * Revision 1.39 2002/02/27 18:22:09 alex
+ * - neue Funktion Client_SetAway() und Client_Away() implementiert.
+ *
+ * Revision 1.38 2002/02/27 14:47:53 alex
+ * - Logging beim Abmelden von Clients (erneut) geaendert: nun ist's aber gut ;-)
+ *
+ * Revision 1.37 2002/02/17 19:02:49 alex
+ * - Client_CheckNick() und Client_CheckID() lieferten u.U. falsche Ergebnisse.
+ *
+ * Revision 1.36 2002/02/06 16:49:41 alex
+ * - neue Funktion Client_IsValidNick(), Nicknames werden besser validiert.
+ *
+ * Revision 1.35 2002/01/29 00:14:49 alex
+ * - neue Funktion Client_TopServer(), Client_NewXXX() angepasst.
+ *
+ * Revision 1.34 2002/01/27 22:07:36 alex
+ * - Client_GetFromID() besser dokumentiert, kleinere Aenderungen.
+ *
+ * Revision 1.33 2002/01/27 21:56:54 alex
+ * - weitere Anpassungen an Chennals, v.a. ueber Server-Links.
+ *
+ * Revision 1.32 2002/01/27 18:27:12 alex
+ * - Client_GetFromID() kommt nun auch mit Host-Masken zurecht.
+ *
+ * Revision 1.31 2002/01/21 00:08:50 alex
+ * - wird ein Client entfernt, so wird er auch aus allen Channels geloescht.
+ *
+ * Revision 1.30 2002/01/18 15:32:01 alex
+ * - bei Client_SetModes() wurde das NULL-Byte falsch gesetzt. Opsa.
+ *
+ * Revision 1.29 2002/01/16 22:10:35 alex
+ * - neue Funktionen Client_xxxCount().
+ *
+ * Revision 1.28 2002/01/11 23:50:40 alex
+ * - Hop-Count fuer den Server selber (0) wird korrekt initialisiert.
+ *
* Revision 1.27 2002/01/09 01:08:08 alex
* - wird ein Server abgemeldet, so wird anderen Server ein SQUIT geschickt.
