This change replaces all calls to the old vboot1 SHA library with their
vboot2 equivalents.
This is the first in a long series of changes to move the core vboot kernel
verification into vb2, and the control/display loop out to depthcharge.

This is preparation for a refactoring of how files are traversed.
file_type.inc will specify functions to recognize, show, or sign
each type of file.
This change puts the recognizer functions in file_type.inc, but
just stubs out the show and sign commands.

This moves the what-kind-of-file-is-this logic into a separate
file, and makes it work by calling distinct recognizers until one
hits. A new "-t" option to the show command prints what it's

When re-signing a kernel partition and writing the result into a

instead of creating a new file that's the size of the entire

Also add a test for that.

This adds a field in the GBB header to store the sha256 digest of
the HWID string, and updates gbb_utility so that it stores the
digest when it modifies the HWID. Because this is a new field,
the GBB_MINOR_VER is incremented.

Since the GBB is in the RO firmware, there should be no side
effects for existing devices (but even without that, they should
handle a minor version change without complaint).
