Add architecture test for the non-standard avr-size patch, so that it is not tested on architectures where the patch isn't available.

Added new doxygen_upgrade and doxygen_create targets to the DOXYGEN build system module. Clean up CORE build system module.

Document build system targets. Add a rule to the BUILD module that is run if a source file does not exist to show an error to the user, rather than running the check-source rule before each build (slightly faster/more portable and the generated error is then a true make error).

Clean up BUILD module info output formatting, remove explicit gcc-version target and add ability to generate assembly listings of compiled source files for debug purposes.

Update the BUILD build system module to early abort and display an error if needed before trying to create the OBJDIR output object file directory.

Upgrade Doxygen configuration files, custom style CSS and DOXYGEN build module for the latest Doxygen release.

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

Revert the default DEBUG_LEVEL setting from 3 to 2, as this is apparently causing segfaults on some builds of binutils-avr.

Add DEBUG_FORMAT and DEBUG_LEVEL optional parameters to the BUILD module. Turn off generation of debug information when performing a validation build, and when running the build tests.

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.

Rename hid-teensy and hid-teensy-ee targets to teensy and teensy-ee to be in line with the DFU module target names.

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

Fix up makefile .NOTPARALLEL heuristics so that linear building is only enforced if no object folder set and the "all" target is run. Rename library "ConfigDescriptor.c" file to "ConfigDescriptors.c" to ensure that object filenames are unique.

Add check and error to the BUILD module if OBJDIR option is set but object filenames are not unique.

Clean up HID EEPROM loader shim application code, simplify project makefile. Ensure shim application is properly rebuild by explicitly cleaning it before requesting a rebuild.

Update BUILD build system module with OBJECT_FILES variable, for additional user-specified object files. Update HID build module with a small shim application to reprogram the EEPROM of a target.

Fix LUFA_SRC_PLATFORM makefile variable in the SOURCES build module to use LUFA_ROOT_PATH rather than LUFA_PATH.

Make sure dependency files are generated for assembly files too in the BUILD build system module. Minor code cleanups.

Move out BUILD build system module start and end messages to the respective targets, as they are only used once.

Add svn:eol-style property on all source files where it was missing. Fix line endings of all makefile, *.c and *.h files.

Enable GCC's -pipe option by default, to build projects using intermediary logical OS pipes rather than temporary files on disk.

Minor build system improvements - move out AVRDUDE base flags into a makefile variable, clean up BUILD module.

Add ability to generate SYM files in the BUILD module. Clean up build system output to be slightly more human readable.
