deltas: fuzz tests for delta file and dms

Here are new fuzz tests for deltafile-test and deltamemstore-test that
generate random deltas and iterate over them using random snapshots, testing
the various delta iterator functions. I found this to be a simpler
environment in which to debug delta-related issues, vs. more heavy-weight
tests (i.e. fuzz-itest).

The test introduces MirroredDeltas, a utility that's useful for tracking
deltas that are written into a delta file or DMS.
