Subject: [PATCH] Add udev mode to bluetoothd
Add --udev option to bluetoothd, to allow it to be started on-demand
from udev.
When a new adapter appears, udev would launch bluetoothd --udev.
To avoid problems with udev, bluetoothd --udev would only return
an error exit code if it wasn't already running and a real error
occurred.
When no more Bluetooth adapter are present on the system, bluetoothd
will exit after a 30 second timeout.
