Fix broken documentation in the CDC and DFU class bootloaders due to Doxygen's confusion over the ATTR_NO_INIT attribute macro.

Speed up build tests by only building each test to the ELF output stage (when all files are compiled and linked), rather than to the full HEX output stage as the resulting binary is not actually required.

Changed board LED driver implementations of LEDs_ToggleLEDs() for the AVR8 architecture to use the fast PIN register toggle alternative function for speed.

Fixed broken MIDI host driver MIDI_Host_ReceiveEventPacket() function due to not unfreezing the MIDI data IN pipe before use (thanks to Michael Brown).

Increased endpoint polling interval for all demos and projects to 5ms, as 1ms was causing some enumeration issues on some machines (thanks to Riku Salminen).

Add additional preprocessor sanity checks for the XMEGA platform based on the USB controller input clock speed.

Fixed possible deadlock in the CDC device driver if the USB connection is dropped while the CDC_REQ_SetLineEncoding control request is being processed by the stack (thanks to Jonathan Hudgins).

Fixed incorrect DFU version number reported to the host in the  DFU bootloader descriptors. Fixed incorrect version hundredths value encoding in VERSION_BCD() macro (thanks to Georg Glock).

The library bootloaders will now correctly start the user application after a watchdog-based application start, even if the /HWB line is held low externally during the reset phase.

Changed MIDI event structure MIDI_EventPacket_t to use a single field for the combined virtual cable index and command ID, to prevent bitfield packing issues on some architectures (thanks to Darren Gibbs).

Alter the bootloader section sizes to all be 8KB, to be in line with the default AT90USB1287 fuses, as that is the default target MCU. Add instructions to the documentation to clarify this for the user (thanks to Georg Glock).

Fix up static analysis build test so that inline suppressions for missing header files are not required in the XPLAINBridge project.

Fixed AVRISP-MKII programmer project reset line polarity inverted when the generated EEP file is loaded into the USB AVR's EEPROM and avr-dude is used.

Make sure CRC value is pre-zeroed before reading from the XMEGA target device, to prevent corrupt data from being returned to the host in the AVRISP-MKII Clone project.

Fixed incorrect reponse to GET STATUS requests in device mode if NO_DEVICE_SELF_POWER or NO_DEVICE_REMOTE_WAKEUP tokens are defined (thanks to Georg Glock).

Fixed CDC and DFU bootloaders failing to compile when the bootloader section size is 8KB or more (thanks to Georg Glock).

Fix typos in the LUFAConfig.h header file. Add missing modules to the AVR8 architecture ModuleTest build test makefile.
