The firmware verification code no longer assumes that verification data and firmware data are contiguous and follow each other. Needed for EFI where the actual firmware must be stored in its own firmware volume. BUG=1704 TEST=modified existing tests for the new API, and they still pass Review URL: http://codereview.chromium.org/1578035
