evdev: Combine evdev_handle_device() and evdev_configure_device()

Browse source 
We split the device probing and idenfication somewhat arbitrarily between
these two functions.  This commit combines them into one.  Return of -1
indicates error, 0 success, but succesful probing can return a device
with device->caps == 0, which means we don't handle the device.
