Summary:
address an existing limitation on compaction triggering mechanism that relies on events like flush/compaction/SetOptions. This is important for periodic compactions where files can become eligible without any of these events. The periodic task now runs every 12 hours and check CFs that enables `periodic_compaction_second` (TBD if we want to expand to all CFs) for eligible compactions.
Some of the periodic tasks probably don't need to run immediately after Register(). I'm keeping the existing behavior for now for patch release and to makes tests happy.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/13736
Test Plan:
- new unit test that fails before this change.
- ran crash test for hours with the periodic task running every 5 seconds: `python3 ./tools/db_crashtest.py blackbox --test_batches_snapshot=0 --periodic_compaction_seconds=10`

Summary:
In preparing some seqno_to_time_mapping improvements, I found that some of the wrap-up work for creating column families was unnecessarily repeated in the case of DB::Open with create_missing_column_families. This change fixes that (`CreateColumnFamily()` -> `CreateColumnFamilyImpl()` in `DBImpl::Open()`), motivated by avoiding repeated calls to `RegisterRecordSeqnoTimeWorker()` but with the side benefit of avoiding repeated calls to `WriteOptionsFile()` for each CF.
Also in this change:
* Add a `Status::UpdateIfOk()` function for combining statuses in a common pattern
* Rename `max_time_duration` -> `min_preserve_seconds` (include units as much as possible)
* Improved comments in several places

Summary:
We haven't been actively mantaining RocksDB LITE recently and the size must have been gone up significantly. We are removing the support.
Most of changes were done through following comments:
unifdef -m -UROCKSDB_LITE `git grep -l ROCKSDB_LITE | egrep '[.](cc|h)'`
by Peter Dillinger. Others changes were manually applied to build scripts, CircleCI manifests, ROCKSDB_LITE is used in an expression and file db_stress_test_base.cc.

Summary:
Timer has a limitation that it cannot re-register a task with the same name,
because the cancel only mark the task as invalid and wait for the Timer thread
to clean it up later, before the task is cleaned up, the same task name cannot
be added. Which makes the task option update likely to fail, which basically
cancel and re-register the same task name. Change the periodic task name to a
random unique id and store it in periodic_task_scheduler.
Also refactor the `periodic_work` to `periodic_task` to make each job function
as a `task`.
