Clean up and clearly differentiate required and optional items in configuration files. Enable the system command and synchronize configuration options between all CPU architectures. Replace the UEFI_ENV macro with UEFI_C_SOURCE to align with Linux and Posix conventions. Update copyrights and versions and make minor cosmetic enhancements to files. Fix compiler-specific build errors. Add Python-specific ReadMe file.
