9978e0aa00 vboot: fix name-collision with OpenSSL.
vboot currently uses the |SHA256_CTX| name, which is claimed by OpenSSL.
To work around this, it defines OPENSSL_NO_SHA, but that can't be done
at compile time:

The OPENSSL_NO_* defines are set by OpenSSL to reflect the configuration
that it was built with so that users of OpenSSL can disable features as
needed. They can affect the contents of structures any thus the ABI of
the library.

If these defines are set outside of OpenSSL, then the library and the
code that uses it will have incompatible ABIs. At that point it's only
functioning by blind luck.

This change renames the name-collisions so that this hack isn't needed.
This is the same change as was made internally in cl/85758149.

b5a439241f futility: add support for usbpd1 images
The USB Type-C chargers released with Samus ("Pixel (2015)") have
upgradable firmware. Those firmware images are currently signed
by some custom scripts. This adds support for those images to
futility, so that those custom scripts can be replaced.

Note that due to space considerations, the usbpd firmware images
don't have room for handy things like an FMAP or headers for the
signatures. Accordingly, all the normally variable factors (image
size, signature algorithms, etc.) are hard coded and the image
itself just looks like a bunch of random numbers. Because of
this:

1. There's no way to recognize this type of file, and nothing to
   display about it.

2. You have to give the "--type usbpd1" arg to the sign command.

3. I'm designating this file type "v1" because I hope that the
   firmware for any future adapters will be more readily
   identifiable.

TEST=make runtests

This adds a new test that signs usbpd1 firmware images using
futility, and compares the result to the same files signed by the
custom scripts, ensuring that they are bitwise identical.

01466d36af futility: Let each command provide its own help
Instead of a separate help function for each command, let's just
require each command to handle a --help option. This will make it
easier to layer the commands (for example, "sign" could have
several subcommand variants, each with its own help).

BUG=none
BRANCH=none
TEST=make runtests

I also compared the result of running "futility help CMD" before
and after this change. The help still shows up correctly.

49a422fab9 futility: change longhelp functions to take multiple args
Some of the help messages are getting pretty long. We should
allow each command to provide additional help details only when
asked.

I also compared the help messages for all commands, both before
and after this change to ensure that nothing was different.

something else.

0f21441e78 vb21: Replace the key GUID with a sha1sum instead
We want a quick and human-friendly way to match keys with
signatures, so we decided to give each key a unique GUID and
carry that ID around when signing things.

But then we realized that we could autogenerate a unique
identifier from the .pem file itself, which is even better
because then we can match our binary keypair structs with the
openssl file used to generate them.

This change replaces the GUID id with a sha1sum calculated from
the public key's "keyb" blob.

BUG=none
BRANCH=none
TEST=make runtests

Also:

  futility show tests/testkeys/key_rsa4096.pem
  futility create tests/testkeys/key_rsa4096.pem foo
  futility show foo.vbp*

Note that the GUID is the same for all files.

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.
