Also removes the dev_mode flag from Firmware Image verification as key signature for the firmware should be checked whether or not dev mode is enabled. BUG=670 TEST=All tests still pass. Merge remote branch 'refs/remotes/origin/master' into fixtests Fix tests, remove dev mode. Move common code. Review URL: http://codereview.chromium.org/1280002
