Device scope wrapper for bluetooth

[Elad Efrat <elad%NetBSD.org@localhost>]

Hi,

I'd like to use kauth(9) in the bluetooth code (netbt, dev/bluetooth).

I think it makes sense to add bluetooth to the device scope, perhaps
with its own authorization wrapper, see kauth_device_authorize_tty()).

Actions will be named similarly, for example,
KAUTH_DEVICE_BLUETOOTH_{ATTACH,ENABLE,CONFIG,SETPRIV,...}.

Are there any objections for this approach?

Thanks,
