ChooseBinlogsForIncrementalBackup chooses which binary logs need to be backed up in an incremental backup, given a list of known binary logs, a function that returns the "Previous GTIDs" per binary log, and a position from which to backup (normally the position of last known backup) The function returns an error if the request could not be fulfilled: whether backup is not at all possible, or is empty.
