This allows the user to manually specify the type of an input

This also adds a test to ensure that futility doesn't coredump if
you give it the wrong type (although I'm sure it's not exhaustive).

The host-side futility tool will need to support all extant vboot
implementations. Some legacy futility commands only support the
original vb1 format, but others ("show" or "sign", for example)
may need to be instructed which formats to expect or emit.
This change adds some global args to specify the preferred
formats. It also cleans up a few [unused AFAICT] one-letter args
to avoid conflicts.

Now that futility is pretty much working as intended, we don't
have to be quite so picky in the way it's being invoked. Up until
now, it's only worked when invoked as "futility" or as one of the
built-in commands, such as "dump_fmap".
This change removes those restrictions. You can invoke futility
under any name you wish. If it recognizes the name as a built-in
command, great. Otherwise it will require a valid command as the
first arg, just like it always has.

not directly related to verified boot:
cgpt

Also, dumpRSAPublicKey is removed from the target, since it is only used on
the build host to create new keypairs.

In almost every case we want the dynamically linked version of futility,
because it's smaller and the openssl functions require it (they use
dl_open() to invoke the correct RSA libraries).
However, the AU shellball requires three futility functions (crossystem,
gbb_utility, and dump_fmap). Those pretty much have to be built statically,
because they run from the new rootfs and packing all the dynamic libraries
into the shellball is way too large and complicated.
This change prepares to build both futility (full featured) and futility_s
(just those functions). The scripts that create the AU shellball will
already choose futility_s from /build/$BOARD/.

Nothing to test just yet. The AU shellball is currently broken (it uses the
dynamic version of futility and doesn't copy the symlinks anyway), so this
should have no effect. We just need to ensure that the _s version doesn't go

This moves all the old userspace utilities generated by vboot_reference into
a subdirectory not in $PATH, and replaces them with symlinks to a single
executable named 'futility'. At the moment that utility just execs the
original utilities (optionally logging that fact first).
Ultimately, the old utilities will be subsumed into a single binary instead
of multiple separate executables.
