+ 
+Patchable constant for licencee to set devsound server thread priority
+Licencees should ensure that the devsound server thread priority is equal to the system server priority for better responsiveness.
+If SYMBIAN_CURB_SYSTEMSERVER_PRIORITIES is defined, setting devsound server thread priority to EPriorityAbsoluteHigh will ensure
+devsound server's thread priority is set to system server's priority.
+If the macro is unavailable it is recommended to use EPriorityAbsoluteRealTime1. Usage of EPriorityAbsoluteRealTime1 requires ProtServ capability.
+The constant can be changed at ROM build time using patchdata OBY keyword.
