Changed the signature of the CALLBACK_USB_GetDescriptor() callback function so that the descriptor pointer is const, to remove the need for extra casting inside the callback (thanks to Jonathan Kollasch).

* - Changed all Device mode LowLevel demos and Device Class drivers so that the control request is acknowledged and any data
* transferred as quickly as possible without any processing inbetween sections, so that long callbacks or event handlers will
* not break communications with the host by exceeding the maximum control request stage timeout period

* - A new USB driver source file, Drivers/USB/HighLevel/PipeStream.c now exists. This source file should be added to all

+ * - The signature for the CALLBACK_USB_GetDescriptor() callback has changed, the "void** const DescriptorAddress" parameter is
+ * now "const void** const DescriptorAddress". Existing applications should update their callback signatures to match this, and
+ * eliminate any casting of descriptor pointers to a non-const pointer.
