Add a test function helper, test_oid, that produces output that varies
depending on the hash in use. Add an additional helper, test_oid_cache,
that can be used to load data for test_oid, either through a list of
filenames or on standard input. Check that these functions work in
t0000, as the rest of the testsuite will soon come to depend on them.
Implement two basic lookup charts, one for common invalid or synthesized
object IDs, and one for various facts about the hash function in use.
Individual tests can use their own translation files to map object IDs
or other data that needs to vary across hash functions. Provide
versions for both SHA-1 and SHA-256.
Note that due to the implementation used, keys cannot be anything but
shell identifier characters.
