Bug 1146926: Allow attaching a worker to a CPOW window without invoking CPOW operations. r=gabor
By sending the CPOW to the child processes the one that owns it will create the
child worker and then send back the url of the window to set up the parent
side of the worker.
There are two breaking changes here. Workers invoked in this way no longer
attach synchronously. We no longer pass the window through the attach event.
