UI fw: load handheld audio mode on boot We have now reached the point where use of audio mode config files should be considered mandatory. In ACI usage we can tell users that they need to perform an AT@AUL of some appropriate audio mode, but in UI-enabled fw we really need to have the firmware load audio modes on its own, so that correct audio config gets established when the handset or development board runs on its own, without a connected host computer. Once have FC Venus with both main and headset audio channels and headset plug insertion detection, our fw will need to automatically load the handheld mode or the headset mode depending on the plug insertion state. For now we load only the handheld mode, which has been tuned for FC-HDS4 on FC Luna.

   T_DRV_SIGNAL - driver signal identification
 
   The type defines the signal information data used to identify a signal. 
   This data type is used to define and to report a signal. A signal is 
   defined by a process calling the driver function drv_SetSignal. An 
   event is signalled by driver by calling the pre-defined signal call-
   back function.

   T_DRV_CB_FUNC - driver signal device control block
  
   This type defines a call-back function used to signal driver events,
   e.g. driver is ready to accept data. The driver calls the signal
   call-back function when a specific event occurs and the driver has
   been instructed to signal the event to a specific process. A process
   can set or reset event signalling by calling one of the driver 
   functions drv_SetSignal or drv_ResetSignal. Event signalling can only
   be performed when a call-back function has been installed at driver
   initialization.
