+Subject: [PATCH 7/8] Add own rule result unavailability handling
+
+Own rule result unavailability is handled like send rules - dispatching
+messages from the sender is blocked and resumed when result becomes
+available.
+
+Handler of "RequestName" method needs to return BUS_RESULT_LATER when
+policy result is not known therefore its return type is modified.
+Since bus message handlers are put into function pointer array other
+message handler function singatures are also affected.
+
+Change-Id: I4c2cbd4585e41fccd8a30f825a8f0d342ab56755
