Summary: The `FileMetaData` objects associated with table files already contain the number of the oldest blob file referenced by the SST in question. This patch adds the inverse mapping to `BlobFileMetaData`, namely the set of table file numbers for which the oldest blob file link points to the given blob file (these are referred to as *linked SSTs*). This mapping will be used by the GC logic. Implementation-wise, the patch builds on the `BlobFileMetaDataDelta` functionality introduced in https://github.com/facebook/rocksdb/pull/6835: newly linked/unlinked SSTs are accumulated in `BlobFileMetaDataDelta`, and the changes to the linked SST set are applied in one shot when the new `Version` is saved. The patch also reworks the blob file related consistency checks in `VersionBuilder` so they validate the consistency of the forward table file -> blob file links and the backward blob file -> table file links for blob files that are part of the `Version`.

Summary: If `options.wal_recovery_mode == WALRecoveryMode::kPointInTimeRecovery`, RocksDB stops replaying WAL once hitting an error and discards the rest of the WAL. This can lead to data loss if the error occurs at an offset smaller than the last sync'ed offset. Ideally, RocksDB point-in-time recovery should permit recovery if the error occurs after last synced offset while fail recovery if error occurs before the last synced offset. However, RocksDB does not track the synced offset of WALs. Consequently, RocksDB does not know whether an error occurs before or after the last synced offset. An error can be one of the following. - WAL record checksum mismatch. This can result from both corruption of synced data and dropping of unsynced data during shutdown. We cannot be sure which one. In order not to defeat the original motivation to permit the latter case, we keep the original behavior of point-in-time WAL recovery. - IOError. This means the WAL can be bad, an indicator of whole file becoming unavailable, not to mention synced part of the WAL. Therefore, we choose to modify the behavior of point-in-time recovery and fail the database recovery.

Summary: https://github.com/facebook/rocksdb/pull/6901 subtly changed the handling of the corner case when a table file is deleted from a level, then re-added to the same level. (Note: this should be extremely rare; one scenario that comes to mind is a trivial move followed by a call to `ReFitLevel` that moves the file back to the original level.) Before that change, a new `FileMetaData` object was created as a result of this sequence; after the change, the original `FileMetaData` was essentially resurrected (since the deletion and the addition simply cancel each other out with the change). This patch restores the original behavior, which is more intuitive considering the interface, and in sync with how trivial moves are handled. (Also note that `FileMetaData` contains some mutable data members, the values of which might be different in the resurrected object and the freshly created one.) The PR also fixes a bug in this area: with the original pre-6901 code, `VersionBuilder` would add the same file twice to the same level in the scenario described above.

Summary: Application can ingest SST files with file checksum information, such that during ingestion, DB is able to check data integrity and identify of the SST file. The PR introduces generate_and_verify_file_checksum to IngestExternalFileOption to control if the ingested checksum information should be verified with the generated checksum. 1. If generate_and_verify_file_checksum options is *FALSE*: *1)* if DB does not enable SST file checksum, the checksum information ingested will be ignored; *2)* if DB enables the SST file checksum and the checksum function name matches the checksum function name in DB, we trust the ingested checksum, store it in Manifest. If the checksum function name does not match, we treat that as an error and fail the IngestExternalFile() call. 2. If generate_and_verify_file_checksum options is *TRUE*: *1)* if DB does not enable SST file checksum, the checksum information ingested will be ignored; *2)* if DB enable the SST file checksum, we will use the checksum generator from DB to calculate the checksum for each ingested SST files after they are copied or moved. Then, compare the checksum results with the ingested checksum information: _A)_ if the checksum function name does not match, _verification always report true_ and we store the DB generated checksum information in Manifest. _B)_ if the checksum function name mach, and checksum match, ingestion continues and stores the checksum information in the Manifest. Otherwise, terminate file ingestion and report file corruption.

Summary: This saves up to two key comparisons in block seeks. The first key comparison saved is a redundant key comparison against the restart key where the linear scan starts. This comparison is saved in all cases except when the found key is in the first restart interval. The second key comparison saved is a redundant key comparison against the restart key where the linear scan ends. This is only saved in cases where all keys in the restart interval are less than the target (probability roughly `1/restart_interval`).

Summary: In db_options.c, we should avoid including header files in the `db` directory to avoid introducing unnecessary dependency. The reason why `version_edit.h` has been included in `db_options.cc` is because we need two constants, `kUnknownChecksum` and `kUnknownChecksumFuncName`. We can put these two constants as `constexpr` in the public header `file_checksum.h`.
