[evolution-patches] Fix for #58643 ( Calendar - GW backend) - deriving the gw item id from the itip message

[Harish Krishnaswamy <kharish novell com>]

hi,

 The patch adds code for correctly deriving the gw item id from the itip
message by inserting the type markers for event and todo items.
(macros GW_EVENT_TYPE_ID and GW_TODO_TYPE_ID). This enables us to
assemble the id and handle accept/decline requests even if we have not 
received an update from the soap interface.

+
+	Fixes #58643 - the gw backend assembles the xgwrecordid
+	to be used for accept/decline requests using the type markers.
+
+	* backends/groupwise/e-cal-backend-groupwise-utils.c:
+	(e_gw_connection_send_appointment): use the event and todo type
+	markers while assembling the gwrecordid from the itip message.
+	set flag 'remove' for decline/retract requests to indicate 
+	these should be removed from cache.
+	* backends/groupwise/e-cal-backend-groupwise-utils.h:
+	Add parameter to e_gw_connection_send_appointment and define macros
+	GW_EVENT_TYPE_ID and GW_TODO_TYPE_ID.
+	* backends/groupwise/e-cal-backend-groupwise.c: (receive_object):
+	update the cache based on the remove flag set by 
+	e_gw_connection_send_appointment.
