As the C++ part exposes now SequenceNumber retrieval
for Snapshots we want this obviously also in the Java API.

Summary: Add CappedFixTransform, which is the same as fixed length prefix extractor, except that when slice is shorter than the fixed length, it will use the full key.

Summary: DBTest.SharedWriteBuffer uses an Options that doesn't pass CurrentOptions(), so that it doesn't use MockEnv. However, DBTest's constructor uses MockEnv to call DestoryDB() to clean up, causing uncleaned state before it runs.
Test Plan: Run the test modified to make sure they pass default Env and SharedWriteBuffer now passes MockEnv.

Summary:
There's a bug in TSAN (or libstdc++?) with std::shared_ptr<> for some reason. In db_test, only FlushSchedule is affected.
See more: https://groups.google.com/forum/#!topic/thread-sanitizer/vz_s-t226Vg
With this change and all other @sdong's and mine diffs, our db_test should be TSAN-clean. I'll move to other tests.
Test Plan: no more flush schedule when running TSAN

Summary:
ThreadSanitizer complains data race of super version and version's destructor with Get(). This patch will fix those warning.
The warning is likely from ColumnFamilyData::ReturnThreadLocalSuperVersion(). With relaxed consistency of CAS, reading the data of the super version can technically happen after swapping it in, enabling the background thread to clean it up.

Summary:
1. If WAL directory is different from db directory. Sync the directory after creating a log file under it.
2. After creating an SST file, sync its parent directory instead of DB directory.
3. change the check of kResetDeleteUnsyncedFiles in fault_injection_test. Since we changed the behavior to sync log files' parent directory after first WAL sync, instead of creating, kResetDeleteUnsyncedFiles will not guarantee to show post sync updates.
