Refactor and restructure reference code into individual self-contain modules. I have revamped the way the code is structured to make it easy to determine which parts belong in the firmware and which are used by userland tools. common/ - common utilities and stub functions (Firmware) cryptolib/ - crypto library (Firmware) misclibs/ - miscellaneous userland libraries (Userland) sctips/ - Miscellaenous scripts (Userland) tests/ - Tests (Userland) vfirmware/ - Verified Firmware Implementation vfirmware/firmware_image_fw.c (Firmware) vfirmware/firmware_image.c (Userland) vkernel/ - Verified Kernel Implementation vkernel/kernel_image_fw.c (Firmware) vkernel/kernel_image.c (Userland) Review URL: http://codereview.chromium.org/1581005
