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.

This directory contains interfaces and implementations that isolate the rest of the package from platform details. Code in the rest of the package includes "port.h" from this directory. "port.h" in turn includes a platform specific "port_<platform>.h" file that provides the platform specific implementation. See port_posix.h for an example of what must be provided in a platform specific header file.
