fdf882ded2 Replace namespace name "rocksdb" with ROCKSDB_NAMESPACE (#6433)
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.

420bdb42e7 option_change_migration_test: force full compaction when needed
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.
