Merge branch 'bc/hash-independent-tests'

Many tests hardcode the raw object names, which would change once
we migrate away from SHA-1.  While some of them must test against
exact object names, most of them do not have to use hardcoded
constants in the test.  The latter kind of tests have been updated
to test the moral equivalent of the original without hardcoding the
actual object names.
