Title: Remove BlobBuilder and Payloads.calculateMD5

Callers should instead explicitly set contentMD5, usually with the
results from Guava Hashing.md5(). This narrows the API and removes a
strange IOException from callers. Further it removes a dangerous
rebuffering of arbitrarily-large non-repeatable Payloads.
