vboot2: fix alignment issues on 32-bit architectures
We were assuming 8-byte alignment for buffers. That's not true on
32-bit architectures. We should make the alignment requirements
explicit (and correct) for all architectures.

vboot2: Introduce vb2ex_hwcrypto API
This patch extends the vboot2 API by three callback functions that the
platform firmware may implement to offer hardware crypto engine support.
For now we only support this for hash algorithms, and we will only allow
it for firmware body hashes (not the keyblock or preamble which are too
small to matter execution-time-wise anyway). The API is similar to the
vb2api_*_hash() functions used to start body hashing in the first place,
but we still take this round trip through vboot to allow it to do
key/signature management and retain full control of the verification
process. We also add a new preamble flag to explicitly disable this
feature, so that we can later return to a solely software-based
verification path through a firmware update in case a hardware crypto
engine turns out to be insecure.

TEST='make runtests VBOOT2=1'. Manually booted on Pinky with and without
HW crypto support and with the preamble flag set to confirm expected
behavior. lib21/ parts untested except for compiling and new unit tests.

vboot2: Move old struct handling to lib20/
This is part 4 of a series of changes to rearrange the vboot2 library
so that it's possible to start using the new-style data structs. This
change moves knowledge of the old vboot1 data structs into lib20; 2lib
now contains only code which is common to both vboot2.x libraries
(that is, code which is data structure version agnostic).
No functional changes; just rearranging code and tests.
