Minor corrections for the XMEGA USB controller. Add compile time warning if the USB clock frequency is provably incorrect.

Add missing SVN eol-style property to ensure that source code line endings and converted to the native values on checkout.

Update host C# applications for VS2010. Make LEDNotifier project host applications only display valid COM port names for the PC it is run on, rather than all possible port names. Add missing property files to the TempDataLogger project host application.

Fixed race conditions in the CDC, HID and Mass Storage class drivers when processing some control requests.

Add partial support for the Atmel A3BU Xplained's Dataflash IC (physical USART-as-SPI transport driver still pending).

More XMEGA USB core fixes.

Added INVERTED_ISP_MISO compile time option to the AVRISP-MKII clone project (thanks to Chuck Rohs).

Update ENDPOINT_EPNUM_MASK to be 0x0F, the maximum possible USB endpoint number within a device, rather than just the maximum number for the AVR8 and UC3 targets of 0x07.

Update XMEGA clock management so that the correct 16-bit calibration is used when requested. Fix endpoint descriptor table so that the frame number is stored into the correct location. Add compile time option to source the USB clock from the PLL rather than the internal 32MHz RC oscillator.

XMEGA port improvements; connection and disconnection are now detected correctly. Fixed incorrect interrupt priority levels being set for XMEGA devices.

Fixed CDC class drivers not saving and sending all 16-bits of the control line states (thanks to Matthew Swabey).

Cleanups to the UC3 endpoint/pipe multi byte read code.

Rename the Doxygen page source directory from ManPages/ to DoxygenPages/ to prevent user confusion with the actual *nix Man tool.

Added reliability patches to the AVRISP-MKII Clone project's PDI/TPI protocols (thanks to Justin Mattair).

When automatic PLL management mode is enabled on the U4 series AVR8 chips, the PLL is now configured for 48MHz and not a divided 96MHz, to lower power consumption and to keep the system within the datasheet specs for 3.3V operation (thanks to Scott Vitale).

Fix additional warnings under GCC 4.6.

USB XMEGA support improvements; add DFLL clock platform support, ensure the endpoint table is correctly aligned and configured in the USB controller.

Added reliability patches to the AVRISP-MKII Clone project's ISP and PDI/TPI protocols (thanks to Justin Mattair).

Add core support for the ATXMEGA64A1U.

Minor documentation corrections.

Fix compile error on the UC3 targets when INTERRUPT_CONTROL_ENDPOINT compile time option is used (thanks to Ian Woloschin).

Small size improvement for Little Endian devices when USB host mode is used.

Minor documentation fixes.

Add missing "used" attribute to ATTR_INIT_SECTION to ensure functions declared with that meta-attribute are not discarded by the linker.

Add missing function and definition documentation.
