Write contents of the current contents of this (including any scrollback history) to stream
according to flags.
If cancellable is not null, then the operation can be cancelled by triggering the
cancellable object from another thread. If the operation was cancelled, the error g_io_error_cancelled
will be returned in throws.
This is a synchronous operation and will make the widget (and input processing) during the write operation, which may take a long time
depending on scrollback history and stream availability for writing.
