Firmware-side code for LoadKernel() is in place now. LoadFirmware() replacement coming soon.
The new functions are implemented in parallel to the existing ones (i.e., everything that used to work still does).

BUG=670
TEST=Adds kernel_image_test which tests the new functions.
The kernel image verification pretty much exactly mirror the already existing firmware image verification functions except with a few different/additional fields in a signed kernel image. The firmware signing key is the root key equivalent for kernel images.
This CL also moves the image verification tests to a different script. There's some additional cleanup of the code that I will be submitting separately after this and another pending patches get LGTMed and land.
