Enable -Wcast-align warning for the UC3 architecture in the ModuleTest build test now that the test passes with it.

Minor documentation improvements.

Fix errors uncovered by the new build test compile warnings; fix UC3 pipe configuration function broken, redundant function prototypes and unused parameters.

All USB Class Driver configuration struct values are now non-const, to allow for run-time modifications if required before configuring an instance.

Update ModuleTest build test to use as many compile warnings as possible. Set -Werror so that any generated warnings produce an error.

Update build test "ModuleTest" to check platform drivers where possible. Add missing copyright/license headers.

Oops - don't reset AVRISP-MKII timeout in XPROG mode, as this is synchronous serial and data is always received regardless of attached or non-attached target.

Fix UC3 Interrupt Management platform driver not compiling under C++.

Add build tests to verify correct compilation of as many modules as possible under as many architectures as possible.

Fix broken compilation of LUFA under C++ compilers when the Serial peripheral module header file is included in a C++ source file.

Fix missing semicolon in the UC3 architecture host pipe functions.

Fix failed compilation for the XMEGA architecture if USB_DEVICE_ONLY us not specified.

Fix Dataflash driver for the XMEGA-B1 XPLAINED - the Dataflash is connected to the USART module, but requires physical port remapping.

Modify board Dataflash drivers so that each individual board is responsible for including the correct peripheral driver (SPI or SerialSPI) based on the board connections to the Dataflash chip.

Complete A3BU-XPLAINED and B1-XPLAINED board Dataflash drivers.

Fix XMEGA SPI peripheral driver's incorrect const-ness on the SPI peripheral struct.

Altered the HID class driver to only try to construct at maximum one packet per USB frame, to reduce CPU usage.

Fix XMEGA architecture not correctly resetting the device address and endpoints in response to a USB bus reset from the host.

Update XMEGA board drivers to use the port inversion feature of the XMEGA architecture rather than performing the inversion in software. Add partially completed XMEGA-B1-XPLAINED Dataflash board driver and revert implementation of the XMEGA-A3BU-XPLAINED Dataflash driver as the chip is connected to the USART, not the SPI interface.

Make an explicit constant name for the CMDEX bit of the target's NVM command register in the AVRISP-MKII Clone project.

Allow serial strings to be generated on the older AVR8 devices which do not explicitly state they contain unique values in the datasheet, as this appears to be implemented in hardware.

Updated the AVRISP-MKII Clone programmer project to be compatible with the latest version of AVR Studio (version 5.1).

Changed the AVRISP-MKII Clone programmer project to report a fixed 3.3V VTARGET voltage on USB AVRs lacking an ADC instead of 5V to prevent warnings in AVR Studio 5.1 when programming XMEGA devices.

Fix Dataflash driver for the A3BU-Xplained board.

Minor documentation improvements.

Add (still preliminary) support for the ATXMEGA64A4 and ATXMEGA128A4. Fix minor error in the AVRISP-MKII clone project descriptors.

Update LUFAConfig.h with the new compile time options, re-format Doxygen documentation for all compile time options.
