Remove dependency on the "bc" command line calculator tool in the bootloaders to make compiling on Windows easier with only MinGW.

Add help text to the project makefiles to help new users get information on the improved build system.

Rename build system module makefiles from "lufa.MODULE.in" to "lufa_MODULE.mk" to prevent makefile from assuming the include is an old style build rule, slowing down the build process.

Prevent the BUILD module from shell-executing multiple processes to determine the avr-size flags to speed up the build, unless the size rule is invoked.

Add warnings and set warnings as errors to the SingleUSBModeTest build test makefile.

Fix project makefiles - remove trailing slash from LUFA_PATH entries and the XPLAINBridge project AVRISP file include path to prevent build errors.

Add new ATPROGRAM build system module. Add ATPROGRAM and CPPCHECK modules to all application makefiles.

Clean up CORE build system module, use simple rather than recursive make variables for internal constants and $(shell) derived values.

Update project Doxygen and makefiles so that the resulting project documentation hides the unused version value, and uses the same HTML CSS stylesheet as the library core.

AppConfigHeaders: Update bootloaders to use configuration header files, rather than makefile defines.

Add branch for the conversion of demos to use standard C header files for configuration, rather than makefile defined macros.

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).

Make Doxygen fail for any Doxygen output other than unsupported tags (as these are somewhat benign).

Improve exclusion list for the main library export_tar rule to exclude any compiled library files from the export.

Minor bootloader tweaks; make some functions static where possible to reduce the compiled binary size, add additional comments to the makefiles.

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

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.

Added HID class bootloader, compatible with a modified version of the command line Teensy loader from PJRC.com.

Change bootloader makefiles to automatically compute the bootloader starting address from a flash size and bootloader section size, expressed in KB.

Altered all endpoint/pipe stream transfers so that the new BytesProcessed parameter now points to a location where the number of bytes in the transfer that have been completed can be stored (or NULL if entire transaction should be performed in one chunk).

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 compile time option to the CDC class bootloader, to reduce the compiled binary size, as the endpoint initialization order is fixed in the code.

Rename new CDC class bootloader NO_LOCK_BYTE_SUPPORT compile time option to NO_LOCK_BYTE_WRITE_SUPPORT as reads are still permitted.

Clean up CDC bootloader command processing code.

Added new NO_BLOCK_SUPPORT, NO_EEPROM_BYTE_SUPPORT, NO_FLASH_BYTE_SUPPORT and NO_LOCK_BYTE_SUPPORT compile time options to the CDC class bootloader.
