Discussion
This method iterates over pendingChanges and adds the necessary information to the new batch, until there are no more changes or the size of the batch reaches the maximum limit. If the type of change is a record save, the method asks the specified recordProvider block for that record. If the closure returns nil, the method skips that change.
