public CancellableSource (Cancellable? cancellable)
Creates a source that triggers if this is cancelled and calls its callback of type CancellableSourceFunc.
This is primarily useful for attaching to another (non-cancellable) source with add_child_source to add cancellability to it.
For convenience, you can call this with a null Cancellable, in which case the source will never trigger.
The new SocketSource will hold a reference to the Cancellable.
