Update the support routines for generating packs to support both SHA-1
and SHA-256. Compute the trailing pack checksum and its length
correctly depending on the algorithm, and look up the object names based
on the algorithm as well. Ensure we initialize the algorithm facts so
that our callers need not do so.
