Fix errors in the new Audio Host mode Class Driver, which would have prevented data from being sent or received properly by the device.
Add microphone/square wave generation compile time switch to the Low Level AudioOutput Host demo.
Added missing Audio class control request definitions.
Added support for the Audio class GET STATUS request so that it is correctly ACKed when sent by the host.
Minor code cleanups to add const and reformat where missing, as well as abstract out the internal device signature start address into a macro, so that it can be altered to suit particular devices within a single architecture if needed.
Add missing documentation to the USB_Device_States_t enum.
Remove use of avr-libc specific ATOMIC_BLOCK, replace with a new per-architecture set of inline functions to retrieve and manipulate the global interrupt enable bit for each architecture.
Add in documentation for the USB controller common interrupt routine which must be linked to the interrupt controller in the user application on the AVR32 UC3 architecture.
Remove UC3B temp macros related to EEPROM, to ensure that projects requiring this break at compile time rather than at runtime until a solution can be found.
Renamed the Serial byte send/receive functions to remain consistent with the CDC driver's byte functions.
Altered the serial byte receive function to make it non-blocking.
Fixed ReportID not being removed from the feature/out report data array in the HID class driver when Report IDs are used.
Added new MAX() and MIN() convenience macros.
Changed over all project and demo HID report descriptors to use the new HID report item macros.
Moved the HIDParser.c source file to the LUFA/Drivers/USB/Class/Common/ directory from the LUFA/Drivers/USB/Class/Host/.
Added new Endpoint_Null_Stream() and Pipe_Null_stream() functions.
Removed the NO_STREAM_CALLBACKS compile time option due to the new partial stream transfer feature replacing it.
Fixed errors in the incomplete Test and Measurement device demo preventing proper operation (thanks to Pavel Plotnikov).
Add ORDERED_EP_CONFIG to the device Projects (only) that use only a single class driver, or where the endpoint ordering is fixed, to save on compiled binary size.
Added new GCC_FORCE_POINTER_ACCESS() macro to correct GCC's mishandling of struct pointers.
Fixed calculation of timer register reload values derived from F_CPU; must subtract one from the division result for the compare value to be correct.
Change AVRISP-MKII rescue clock speed to 4MHz to ensure that a 125KHz ISP speed works regardless of the target's fuses (i.e. DIV8 set).
Move out private/internal host class driver constants to the common class driver headers, so that they can be used in the Low Level host mode demos.
Ensure all demos, projects and bootloaders use the class driver constants where possible to minimise code repetition.
