I previously refactored some of the signature generation code to directly use the OpenSSL library instead of invoking the "openssl" command line utility. The signature_digest command line utility got lost in the process. This restores the utility which in turn fixes the RSA verification test.

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.

This test checks that signatures with improper padding do not get accepted by the RSA signature verification implementation.

The old VerifyFirmware function (now called VerifyFirmwareImage) works on the FirmwareImage structure. This CL adds a verification function which can be used directly on packed binary verified boot firmware blobs. This function can be used as the reference implementation for verified boot in firmware. In addition, all functions that work on FirmwareImage structure have been renames to distinguish them from those which work on binary firmware blobs.
In addition, this adds some new crypto utility functions and refactors old ones.
BUG=670
TEST=Added tests for the new function and they pass.

In addtion, add test cases and a script to generate them for benchmarking. Also fixes a path problem with the run_rsa_tests.sh script.

Also rename and modify run_tests.sh to only run the RSA verification tests. The SHA message digest tests must now be invoked separately.
