This CL does the following:
1) It adds a SignatureBuf function which uses the OpenSSL library to generate RSA signature. This is more robust than the previous way of invoking the command line "openssl" utility and capturing its output. No more unnecessary temporary files for signature operations.
2) It adds functions that allow direct manipulation of binary verified Firmware and Kernel Image blobs in memory.
3) It changes the structure field members for FirmwareImage to make it consistent with KernelImage. Now it's clearer which key is used when.
4) Minor bug fixes and slightly improved API for dealing verified boot firmware and kernel images.
5) Renames the RSA_verify function to prevent conflicts with OpenSSL since it's linked into the firmware utility binary.

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.

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.
