Summary:
Since AddFile unlock/lock the mutex inside LogAndApply() we need to ensure that during this period other compactions cannot run since such compactions are not aware of the file we are ingesting and could create a compaction that overlap wit this file
this diff add
- WaitForAddFile() call that will ensure that no AddFile() calls are being processed right now
- Call `WaitForAddFile()` in 3 locations
-- When doing manual Compaction
-- When starting automatic Compaction
-- When doing CompactFiles()

Summary: we should not call ShouldStopBefore() in compaction when the compaction targets level 0. Otherwise, CheckConsistency will fail the assertion of seq number check on level 0.
Test Plan:
make all check -j64
I also manully test that using db_bench to compact files to level 0. Without this line change, the assertion files and multiple files are generated on level 0 after compaction.

Revert the behavior where we don't read sequence id from WAL, but increase it as we replay the log. We still keep the behave for 2PC for now but will fix later.

Summary:
Many of our diffs dont have sandcastle tests because we failed to load arcanist token file (loaded over the network)
this diff try for at least 5 seconds (once every 0.2 second) to load the file instead of failing the first time the file is not found
This will make it less probable that diffs are submitted without sandcastle tests

If log recycling is enabled with the rocksdb (recycle_log_file_num=16)
db->Writebatch is erroring out with keynotfound after ~5-6 hours of run
(1M seq but can happen to any workload I guess).See my detailed bug
report here (https://github.com/facebook/rocksdb/issues/1303).
This commit is the fix for this, a check is been added not to delete
the log file if it is already there in the recycle list.
Test Plan:
Unit tested it and ran the similar profile. Not reproducing anymore.
Summary: In ColumnFamilyTest.FlushCloseWALFiles, there is a small window in which the flush has finished but the log writer is not yet closed, causing the assert failure. Fix it by explicitly waiting the flush job to finish.
Test Plan: Run the test many times in high parallelism.
