Summary:
When dynamically linking two binaries together, different builds of RocksDB from two sources might cause errors. To provide a tool for user to solve the problem, the RocksDB namespace is changed to a flag which can be overridden in build time.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6433
Test Plan: Build release, all and jtest. Try to build with ROCKSDB_NAMESPACE with another flag.

Summary:
Recently db_stress starts to use a special Env that keeps all manifest files. This should not apply to checkpoint directory and causes test failure like this:
Verification failed: Checkpoint gave inconsistent state. Status is IO error: While mkdir: /dev/shm/rocksdb/rocksdb_crashtest_whitebox/.checkpoint27.tmp: File exists
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6233
Test Plan: Run crash_test with high chance of checkpoint and make sure it doesn't reproduce.

Summary:
compaction history is stored in manifest files. Preserve all of them in db_stress would help debugging.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6142
Test Plan: Run db_stress and observe that manifest files are preserved. Run whole crash_test and see how DB directory looks like.
