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:
When option_change_migration_test decides to go with a full compaction, we don't force a compaction but allow trivial move. This can cause assert failure if the destination is level 0. Fix it by forcing the full compaction to skip trivial move if the destination level is L0.

Summary: OptionChangeMigration() to support FIFO compaction. If the DB before migration is using FIFO compaction, nothing should be done. If the desitnation option is FIFO options, compact to one single L0 file if the source has more than one levels.
Test Plan: Run option_change_migration_test
