And add a vb2_digest_buffer() call which produces the hash of a buffer
all in a single function call. That function actually already
existed, but was in a unit test file rather than in the library
itself. It's a small function, so adding it won't increase the size
of the library significantly - or at all, on platforms which compile
with -ffunction-sections.
This allows coreboot to reuse this SHA library for hashing CBFS
entries and file data. All it has to do is #define
NEED_VB2_SHA_LIBRARY and then #include "vb2_api.h".

And include it in vb2_api.h if VB20 internals are needed.
This allows coreboot to get at the fields more cleanly for now, rather
than duplicating the field definitions. In the long run, we should
have APIs for this rather than having coreboot peek at the bits
directly.

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.

This is what other firmware should include. Other firmware must NOT
attempt to include headers from deeper inside the vboot2
implementation; that will likely break as vboot2 is refactored.
