Removed unused arguments. Load the initial alarms here. (load_alarms): New

2000-05-11  Federico Mena Quintero  <federico@helixcode.com>

	* gui/gnome-cal.c (gnome_calendar_update_all): Removed unused
	arguments.  Load the initial alarms here.
	(load_alarms): New function to load a day's worth of alarms.
	(gnome_calendar_class_init): Eeeek!  This was taking in an
	incorrect argument type.
	(gnome_calendar_init): Now the calendar keeps a hash table of
	UIDs->queued alarms.  Create the hash table here.
	(gnome_calendar_destroy): Destroy the alarms hash table.
	(gnome_calendar_object_updated_cb): Remove the alarms for the
	object and regenerate them.
	(gnome_calendar_object_removed_cb): Remove the alarms for the
	object.

	* gui/alarm.c (alarm_add): Do not take in a CalendarAlarm, just
	the trigger time, the callback and the closure data.  Return an
	opaque identifier for the alarm so that it can be removed by the
	client code if needed.  Use the queue_alarm() helper function.
	(queue_alarm): Helper function to actually queue the alarm and set
	up the itimer.  Deal with a nonzero return value from
	setitimer().
	(alarm_remove): New function to remove an alarm based on its ID.
	(pop_alarm): New helper function; pops the first alarm of the
	queue and resets the timer as appropriate.
	(alarm_ready): Simplified a lot by using pop_alarm().

	* idl/evolution-calendar.idl (Cal): Added get_alarms_in_range().

	* pcs/cal.c (build_instance_seq): New function to build a CORBA
	sequence from the internal list of instances.
	(Cal_get_events_in_range): Use build_instance_seq().
	(Cal_get_alarms_in_range): Implemented new method.

	* pcs/cal-backend.c (cal_backend_get_alarms_in_range): New
	function with the get_alarms_in_range() engine.

	* pcs/cal-backend-imc.c (cal_backend_imc_get_alarms_in_range):
	Implemented the get_alarms_in_range() method.

	* cal-client/cal-client.c (cal_client_get_alarms_in_range): New
	client-side function for getting the alarms.
	(build_instance_list): New helper function to build the
	CalObjInstance list from the CORBA sequence.
	(cal_client_get_events_in_range): Use build_instance_list().

	* gui/calendar-commands.h: #include <cal-util/calobj.h>.  #include
	"gnome-cal.h".

	* gui/e-week-view.c: #include "calendar-commands.h" instead of
	main.h; the latter is an obsolete file and will be killed.

	* gui/evolution-calendar-control.c (main): Call init_bonobo()
	before anything else.  We need the GTK+ object system initialized.

	* gui/Makefile.am (evolution_calendar_SOURCES): Do not use main.h.

	* cal-util/cal-util.c (cal_alarm_instance_list_free): New function.
