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.

This patch remove the unnecessary Compaction::ReleaseInputs().
Compaction::ReleaseInputs() tries to unref its input_version

Summary:
This diff adds BlockBasedTable format_version = 2. New format version brings better compressed block format for these compressions:
1) Zlib -- encode decompressed size in compressed block header
2) BZip2 -- encode decompressed size in compressed block header
3) LZ4 and LZ4HC -- instead of doing memcpy of size_t encode size as varint32. memcpy is very bad because the DB is not portable accross big/little endian machines or even platforms where size_t might be 8 or 4 bytes.
It does not affect format for snappy.
If you write a new database with format_version = 2, it will not be readable by RocksDB versions before 3.10. DB::Open() will return corruption in that case.
Test Plan:
Added a new test in db_test.
I will also run db_bench and verify VSIZE when block_cache == 1GB
