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.

Mark build test makefiles as being incompatible with parallel make builds, as they re-use the same object directories.

Strip out BuildTest sub-makefile contents as much as possible. Remove old UC3 build test makefile from the ModuleTest build test. Add platform module to the example LUFA makefile.

Switch StaticAnalysisTest build test to use the new build system CPPCHECK module. Update additional build tests to all include the core build system module.

Replace architecture specific makefiles in the BuildTests with the new common build system makefiles.

Add missing documentation to custom BuiltTest hardware mapping files. Fix up old copyright years on some makefiles.

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

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.

Update code and StaticAnlysisTest so that missingInclude warnings do not have to be suppressed, and so that all code except for third party libraries can be checked.

Update SingleUSBModeTest makefile to separate out the messages from the test commands.

Update build test "ModuleTest" to check platform drivers where possible. Add missing copyright/license headers.

Fix UC3 Interrupt Management platform driver not compiling under C++.

Add build tests to verify correct compilation of as many modules as possible under as many architectures as possible.

Fix broken compilation of LUFA under C++ compilers when the Serial peripheral module header file is included in a C++ source file.

Fix missing semicolon in the UC3 architecture host pipe functions.

Fix failed compilation for the XMEGA architecture if USB_DEVICE_ONLY us not specified.
