Historically, sha.h included both SHA-1 and SHA-2 functions. But SHA-1
functions mostly shouldn't be used now, and it's useful to be able to
audit at the level of header names in some contexts.
Therefore move SHA-2 things into a new sha2.h. In order not to break
everything, sha.h now includes sha2.h so no changes are needed in
existing callers.
