Instead of calling futil_traverse() to iterate through a preset list of functions, this establishes a separate show() and sign() function for each type of file. The only significant change is that walking through the FMAP areas within BIOS images is done in BIOS-specific functions instead of that being the "normal" case with every other type of file skipping that traversal. This is a refactoring only. There is no externally visible change.
