This is part 1 of a series of 4 changes which rearrange the vboot2
files and unit tests so that we can more cleanly switch over from
old-style structs to new-style structs.
No functional changes, just shuffling around code.
BUG=chromium:423882
BRANCH=none
TEST=make runtests && VBOOT2=1 make runtests (works with/withoug VBOOT2 flag)
And build firmware for veyron_pinky.
