Summary:
DBIter, and in-turn NewDBIterator and NewArenaWrappedDBIterator, take a bunch of params. They can be reduced by passing in ReadOptions directly instead of passing in every new param separately. It also seems much cleaner as a bunch of the params towards the end seem to be optional.
(Recently I introduced max_skippable_internal_keys, which added one more to the already huge count).

Summary:
Check the result of the benchmark againt a specified truth_db, which is
expected to be produced using the same benchmark but perhaps on a
different commit or with different configs.
The verification is simple and assumes that key/values are generated
deterministically. This assumption would break if db_bench using rand
variable differently from the benchmark that produced truth_db.
Currently it is checked to work on fillrandom and readwhilewriting.
A param finish_after_writes is added to ensure that the background
writing thread will write the same number of entries between two
benchmarks.
Example:
$ TEST_TMPDIR=/dev/shm/truth_db ./db_bench
--benchmarks="fillrandom,readwhilewriting" --num=200000
--finish_after_writes=true
$ TEST_TMPDIR=/dev/shm/tmpdb ./db_bench
--benchmarks="fillrandom,readwhilewriting,verify" --truth_db
/dev/shm/truth_db/dbbench --num=200000 --finish_after_writes=true
Verifying db <= truth_db...
Verifying db >= truth_db...

1. Move universal compaction picker to separate files compaction_picker_universal.cc and compaction_picker_universal.h.
2. Rename some functions to make the code easier to understand.
3. Move leveled compaction picking code to a dedicated class, so that we we don't need to pass some common variable around when calling functions. It also allowed us to break down LevelCompactionPicker::PickCompaction() to smaller functions.

Summary:
In RocksDB, we sometimes preallocate the estimated space for a file to have better perf with fallocate (if supported). Usually it is a little bit bigger than the real resulting file size. At this time, we have to let the Filesystem reclaim the space not used.
Ideally, calling ftruncate to truncate the file to its real size should be enough. HOWEVER, it isn't on tmpfs, which we witness in our case, with some buggy kernel version. ftruncate a file with preallocated space doesn't change number of the blocks used by the file, which means the space not used by the file is not returned to the filesystems. So in this case we need fallocate with FALLOC_FL_PUNCH_HOLE to explicitly reclaim the used blocks. It is a hack to cope with the kernel bug and usually we should not need it.

Summary:
Level-based L0->L0 compaction operates on spans of files that aren't currently being compacted. It reduces the number of L0 files, thus making write stall conditions harder to reach.
- L0->L0 is triggered when base level is unavailable due to pending compactions
- L0->L0 always outputs one file of at most `max_level0_burst_file_size` bytes.
- Subcompactions are disabled for L0->L0 since we want to output one file.
- Input files are chosen as the longest span of available files that will fit within the size limit. This minimizes number of files in L0.

Summary:
Refactor WriteImpl() so when I plug-in the pipeline write code (which is
an alternative approach for WriteThread), some of the logic can be
reuse. I split out the following methods from WriteImpl():
* PreprocessWrite()
* HandleWALFull() (previous MaybeFlushColumnFamilies())
* HandleWriteBufferFull()
* WriteToWAL()
Also adding a constructor to WriteThread::Writer, and move WriteContext into db_impl.h.
No real logic change in this patch.
