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.
CQ-DEPEND=CL:236435
BRANCH=None
BUG=chrome-os-partner:32987
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: More specific errors for unimplemented external APIs
When porting vboot2 to a platform, it's common to copy 2stub.c and
then start implementing APIs. Adding explicit errors makes it clearer
when an unimplemented API is called.

vboot2: misc higher-level routines
I'm breaking the last chunk of vboot2 into smaller pieces as I add
tests. This has a bunch of misc routines like the dev switch logic
and GBB header parsing.
