nsBaseDragService keeps track of the processes that might need to cancel a drag with EndDragSession and this is technically correct since the drag session is a singleton in the child process, but this series of patches changes those sessions to be per-PuppetWidget/BrowserChild. This allows content processes to distinguish which of its browsers is engaged in a drag.
