Summary:
We see failure of the test in travis but I can't repro it.
Add more logging in failure cases to help us figure out which failure it is.
Also makes synchronization slightly stronger, though there isn't seem to be a problem without it
Test Plan: Run the test

Summary: Currently fault_injection_test has a test case to drop all the unsynced data. Add one more case to take a randomized bytes from it.

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:
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.

Summary: Now we don't sync manifest file when initializing it, so DB cannot be safely reopened before the first mem table flush. Fix it by syncing it. This fixes fault_injection_test.

Summary:
This is a port of [[ https://github.com/google/leveldb/blob/master/db/fault_injection_test.cc | LevelDB's fault_injection_test ]] to RocksDB. Unfortunately it fails with:
```

#5 ./fault_injection_test() [0x408bb8] _start ??:0
```
so I commented out the test invocation in the source code for now (lines 514-520) so it can be merged.
Test Plan: This is a new test.
