New ARM boards use an FDTMAP, which is basically just an FDT. This means
that we don't have two potentially conflicting flash maps in the image.
Flashrom supports this without issue, but the firmware signer needs
dump_fmap to support it also.
It would be nice if we had libfmap implementing all this, but this is
apparently a long-running clean-up task. So the next best thing is to
deal with the flashmap in one program - i.e. flashrom.
So support FDTMAP in futility by redirecting 'dump_fmap -x' to flashrom.

With the flashrom -x option added, run this:
sudo futility dump_fmap -x /build/peach_pit/firmware/image-peach-pit.bin
gbb_utility --rootkey=rootkey.bin GBB
See that the various chunks of data from the image are output and that
gbb_utility completes without error.

This stops creating dump_fmap as a standalone utility and builds it into
futility. Since it was already invoked as a symlink, no user-visible changes
should be observed.

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
into any of the other images.

This tweaks the Makefile and adds a couple of placeholder tests to prepare
for testing the builtin futility operations. There aren't any useful builtin
functions yet, but this lets us start adding them along with the tests.

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.
There is a matching CL needed to make the recovery image creation work.

To test, build everything, test everything. It should work as before in all
cases. I have built normal images, test images, factory installers, recovery
images; they all seem to work.
I've run trybots on daisy-paladin link-paladin lumpy-paladin and alex-paladin.

Cleaning up the Makefile to add correct dependencies, avoid using variables
before they're fully defined (which required .SECONDEXPANSION to work
around), generally improve readability.
There are so many changes that there's no point in trying to compare old
vs new - just look at the final result. And this still isn't perfect, but
it's a big step forward.
