Summary: Now using memenv, DB will not able to be reopened, since a "//" in the file name. Fix it by normalizing file path.
Test Plan: Add a unit test that used to fail and now pass.

Summary:
This patch remove the unnecessary Compaction::ReleaseInputs().
Compaction::ReleaseInputs() tries to unref its input_version
and column_family. However, such unref is always done in
~Compaction(), and all current ReleaseInputs() calls are
right before the destructor.

Summary:
While running cross-functional tests for weak iterators, I
encountered a bug in GeoDB. GeoDB reads a key from the database and
tries to use it after doing a Seek. Fixing it by storing the key locally
so that it is still visible after the Seek.
Test Plan: Run geodb_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:
```

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.

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

Summary:
In this diff I add another parameter to BlockBasedTableOptions that will let users specify block based table's format. This will greatly simplify block based table's format changes in the future.
First format change that this will support is encoding decompressed size in Zlib and BZip2 blocks. This diff is blocking https://reviews.facebook.net/D31311.
Test Plan: Added a unit tests. More tests to come as part of https://reviews.facebook.net/D31311.

Summary:
Previous to this commit ColumnFamilyDescriptor took a String as name for the ColumnFamily name. String is however encoding dependent which is bad because listColumnFamilies returns byte arrays without any encoding information.
All public API call were deprecated and flagged to be removed in 3.10.0

* Use emplace when possible.
* Make FileInfo shared among all BackupMeta, instead of storing filenames.
* Make checksum_value in FileInfo constant.
* Reserve space beforehand if container size is known.
* Make FileInfo and BackupMeta non-copyable and non-assignable to prevent future logic errors.
It is very dangerous to copy BackupMeta without careful handling refcounts of FileInfo.
* Remove a copy of BackupMeta when detected corrupt backup.
