3855e2e948 futility: show sha1sums for private keys too
Because all of our private key structs carry around the openssl
struct rsa_st data blobs, we can use those blobs to extract the
corresponding public key and generate a digest of it.

This lets us match our public and private keys without having to
rely on the filenames. There's no crypto verification without
actually *using* them, of course, but it's handy for quick reference.

BUG=chromium:231574
BRANCH=none
TEST=make runtests

This also adds a test to ensure that all the public and private
keys generated from the same .pem file have the same sha1sums.

4e4c19602e futility: Add create command to make keypairs from RSA files
This command reads a single .pem file and emits the public and
private keys generated from it. It can produce both the old-style
vboot 1.0 keys (.vbpubk and .vbprivk), or the new vboot 2.1
format keys (.vbpubk2 and .vbprik2). The default is the new
format, but you can give futility the --vb1 arg to force the old
format.

A test is included.

f1f53b3732 vboot: Add flag to vbutil_kernel for reconstruction of vmlinuz image
Adding functionality to allow for rebuilding of vmlinuz after it
has been processed into vblock and header stripped.  Basically appends
the 16-bit header of a vmlinuz image onto the end of the vblock.
BUG=chromium:438302
BRANCH=none
TEST=Successfully ran "make runalltests".
     Also, ran:
     1. Repack kernel block (so that 16-bit header is included):
        "vbutil_kernel --pack kern_0 ..."
     2. Verify kernel: "vbutil_kernel --verify kern_0 ... ".  This should
        be done before booting into kernel, but not necessary for it to work.
     3. Rebuild vmlinuz image:
        "vbutil_kernel --get-vmlinuz kern_0 --vmlinuz-out vm.out"
     4. Set up kexec with vmlinuz (this should complete with no errors):
        "kexec -l vm.out (other kernel cmd line args)"
     5. Boot into kernel:
        "kexec -e"

d241fff54c crossystem: Change ReadFileInt to take an unsigned int pointer
Currently ReadFileInt assumes that an integer value read from a file
is never going to be "-1" and uses that value to indicate failure.
In particular for GPIO values that may be returned by the kernel it
is possible for them to be not simply 0 or 1 but instead a bit within
the GPIO status register that indicates the value.

The function semantics are changed to have the caller pass in the
variable to store the integer in, and use the return code explicitly
as a pass or fail condition.

This requires all the callers of ReadFileInt to be changed to use the
new scheme, and the x86 ReadGpio function is changed to normalize the
GPIO value that is read from the kernel instead of assuming it is
always 1 for active high values.

bc3f0b74f9 cleanup: remove a couple of unused functions and files
scripts/sign_data.sh is just a wrapper to do this:

  ./signature_digest_utility $1 $3 \
    | openssl rsautl -sign -pkcs -inkey $2

AFAICT, that script is only invoked by the SignatureFile()
function in host/lib/file_keys.c, which is not referenced by
anything. I think I can remove both of those things.

Also remove utility/gbb_utility.cc, which should have been done
long ago in commit 6f39615.

782990277a Split libvboot_host.a into external and local libraries.
We've been creating and linking against a library called "libvboot_host.a"
for two different reasons. The main purpose is to build the vboot_reference
tools found in the utility/ directory. But there are some external userspace
programs that would also like to use some functions in this library.

This change establishes libvboot_host.a as the library for use by external
userspace programs only, and creates a new libvboot_util.a library that's
only used inside this source tree to build the vboot utilities.
