This is a first cut at what I envision as a utility we can use to manage our firmware/kernel signing needs. Currently, it implements firmware signing (given a binary image, create a verified boot header) and verification (given a verified boot image, verify it using the given public root key). This CL also fixes the ReadFirmwareImage function from firmware_image to make it more consistent and fixes some bugs. Review URL: http://codereview.chromium.org/652216
