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.
Test Plan: make all check

Summary:
This is first in a series of diffs that fixes data races detected by thread sanitizer.
Here the problem is that we call Ref() on a column family during a single-threaded write, without holding a mutex.
Test Plan: TSAN is no longer complaining about LevelLimitReopen.

Summary:
Prior to this the native library loader instance didn`t
care about a state. So if library loading was called multiple
times, multiple copies of the shared object were put into
the tmp folder and loaded into the JVM.
This changed within this commit to the following behavior:
- library loading is now synchronized
- library is loaded within the first call
- if loading was successful the library loaded sets a flag
- every subsequent call checks for a boolean flag indicating if there was
already a successful attempt
Test Plan:
- Execute example and watch tmp folder while the example is running
- After this patch only one shared object will be in the tmp folder
Usual tests:
- make rocksdbjava jtest
- mvn -f rocksjni.pom package

Summary:
Wrapper classes in fault_injection_test doesn't simulate RocksDB Env behavior close enough. Improve it by:
(1) when fsync, don't sync parent
(2) support directory fsync
(3) support multiple directories
Add test cases of
(1) persisting by WAL fsync, not just compact range
(2) different WAL dir
(3) combination of (1) and (2)
(4) data directory is not the same as db name.
Test Plan: Run the test and make sure it passes.
