Nick Craig-Wood 13591c7c00 Redo error handling for sync/copy/move
* Factor sync/copy/move into its own file
  * Make fatal errors abort the sync
  * Make Copy return errors
  * Make Sync/Copy/Move return the last Copy error if there was one
  * Prioritise returning Fatal errors
  * NoRetry errors are returned if no other types of errors
