It is an invented signal, but it is not rejected. I did not know which
name space to use, so I choose org.bluez because it is a bluez
event. I don't mind using something else if you have a better idea.

I thought D-Bus is the right interface because bluez normally
uses the D-Bus and pressing the headset button is a bluez event.
The reason for this patch was that I wrote an application to handle
mobile phones and it was a nice feature to be able to use the button.
I don't mind dropping that patch completely if you think it is out of
scope for pulseaudio.
