For the purposes of maintaining integrity of a CBFS allow one to
hash a CBFS over a given region. The hash consists of all file
metadata and non-empty file data. The resulting digest is saved
to the requested destination region.
BUG=chrome-os-partner:48412
BUG=chromium:445938
BRANCH=None
TEST=Integrated with glados chrome os build. vboot verification
works using the same code to generate the hash in the tooling
as well as at runtime on the board in question.
