Peter Dillinger c26b75baa5 Deprecate obsolete "backupable db" from public APIs (#8274) ... Summary: An early design of BackupEngine used stackable DB, so I guess a DB had to opt-in to being backupable. Unfortunately the naming of that obsolete design still infects our public API and implementation. This change fixes the public API, with a deprecated backward-compatibility header. `BackupableDBOptions` is renamed to `BackupEngineOptions` (copy-replace in the public header) and backup_engine.h replaces backupable_db.h (present for backward compatibility). The only other change in backupable_db.h -> backup_engine.h is cleaning up headers. Later changes will fix the internal implementation. Pull Request resolved: https://github.com/facebook/rocksdb/pull/8274 Test Plan: The internal implementation of BackupEngine uses the name BackupEngineOptions, while the unit tests use the old name BackupableDBOptions. This gives me confidence that both still work.
