WIP: Hash RAM contents on S3 entry and verify on S3 resume

I used murmur3 since it's supposed to be fast. Though I don't think the
license is really compatible.

The ram_hash code still needs some refactoring to reduce duplication and
to add the ability to handle unaligned blocks.

BUG=b:159081993
TEST=Boot trembyle and see no verification failures.
