These two functions are useful when wrapping FileUndoManager and adding custom commands.
Each command has a unique ID. You can get a new serial number for a custom command
with newCommandSerialNumber(), and then when you want to undo, check if the command
FileUndoManager would undo is newer or older than your custom command.
Record this CopyJob while it's happening and add a command for it so that the user can undo it.
The signal jobRecordingStarted() is emitted.
