USB_CONFIG_ATTR_BUSPOWERED constant renamed to USB_CONFIG_ATTR_RESERVED, as this was misnamed (thanks to NXP Semiconductors).

Run wspurify script on /trunk/ and /branches/ C source files, to remove any trailing whitespace at the end of each line.

Added Class, ClassDevice, ClassHost and ClassCommon to the internal class driver source filenames to prevent ambiguities.

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

Removed the ENDPOINT_DESCRIPTOR_DIR_* macros in favour of the shorter ENDPOINT_DIR_* macros, which can now be used with both Endpoint_ConfigureEndpoint() and in the device descriptors.

Seperate out the device demos and project's configuration descriptor structure definitions to clearly indicate what descriptors belong to which interface.

Add new "checksource" target to the library makefiles, for automated source file existance checking.

Massive corrections to the project documentation and code comments, thanks to Russian translation services provided by Andrey from Microsin.ru.

Replace cast-as-char* byte access of multibyte variables with proper shifts and masks to preserve endianness across different architectures.

Added TWI baud rate prescaler and bit length parameters to the TWI_Init() function (thanks to Thomas Herlinghaus).

Add new ARCH option to the makefiles to (eventually) specify the target device architecture. Update non-usb peripheral drivers to reflect future multiple architecture support.

Add static keyword to all project globals whose scope should be restricted to the same module as they are declared in.

Tighten up the HID class bootloader code slightly, document that it currently exceeds 2KB of bootloader space for all models other than the Series 2 USB AVRs.

Add const to all project descriptor definitions for safety.

Documentation improvements - put driver example code into its own section, fix incorrect and missing section names.

Make a new general RingBuffer.h misc library driver, instead of the per-application LightweightRingBuff.h ring buffers. Change over projects to use the new driver.

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.

Add DEVICE_STATE_AS_GPIOR=0 compile time option to the library projects, to reduce compiled binary size.
