Now that lib20 and lib21 are distinct, they can have overlapping
struct names. This will be cleaner in the long run, since vboot 2.0
(lib20) is just a temporary stepping stone to vboot 2.1 (lib21). It
would be a shame to need to carry around the overhead of that extra
digit forever.
No functional changes, just a lot of renaming.
BUG=chromium:423882
BRANCH=none
TEST=make runtests && VBOOT2=1 make runtests (works with/withoug VBOOT2 flag)
And compile firmware for veyron_pinky
