terminal: raise sysview DEVICE_CHANGE events per attachment
Instead of raising DEVICE_CHANGE only per device, we now raise it per device-session attachment. This is what we want for all sysview users, anyway, as sessions are meant to be independent of each other. Lets avoid any external session iterators and just do that in sysview itself.
