Summary: After https://github.com/facebook/rocksdb/issues/11905, I am preparing a DBImpl change to ensure all sufficiently recent sequence numbers since Open are covered by SeqnoToTimeMapping. **Intended follow-up** However, there are a number of test changes I want to make prior to that to make it clear that I am not regressing the tests and production behavior at the same time. * Start mock time in the tests well beyond epoch (time 0) so that we aren't normally reaching into pre-history for current time minus the preserve/preclude duration. * Majorly clean up BasicSeqnoToTimeMapping to avoid confusing hard-coded bounds on GetProximalTimeBeforeSeqno() results. * There is an unresolved/unexplained issue marked with FIXME that should be investigated when GetProximalTimeBeforeSeqno() is put into production. * MultiCFs test was strangely generating 5 L0 files, four of which would be compacted into an L1, and then letting TTL compaction compact 1@L0+1@L1. Changing the starting time of the tests seemed to mess up the TTL compaction. But I suspect the TTL compaction was unintentional, so I've cut it down to just 4 L0 files, which compacts predictably. * Unrelated: allow ROCKSDB_NO_STACK=1 to skip printing a stack trace on assertion failures.
