Robert 628a67b007 Reduce memory footprint in backupable db. ...

* Use emplace when possible.
* Make FileInfo shared among all BackupMeta, instead of storing filenames.
* Make checksum_value in FileInfo constant.
* Reserve space beforehand if container size is known.
* Make FileInfo and BackupMeta non-copyable and non-assignable to prevent future logic errors.
  It is very dangerous to copy BackupMeta without careful handling refcounts of FileInfo.
* Remove a copy of BackupMeta when detected corrupt backup.
