This CL fixes a bug where the same renderer could open several channels to the same plugin process, which end up having the same name. This CL makes it that there is only one channel for each (plugin, renderer) pair, just like on Windows. The socketpair is created in the plugin process (which can ensure that only one channel per renderer gets created), and sends the renderer side through the browser process. Note: this should essentially be a noop on Windows.
