o drop support for node names in name stack, support only symlinks With well defined and kernel-supplied node names, we no longer need to support a possible stack of conflicting symlinks and node names. From there on, only symlinks with identical names can be claimed by multiple devices. It will simplify the logic a lot and shrink /dev/.udev/names/ significantly. Also exclude "*/MAJ:MIN" link names from the name stack, they can not conflict. o remove most NAME= rules (they are provided by the 2.6.31 kernel) o get rid of braindead "scan all devices to find myself" libusb interface if it can not be fixed, drop libusb entirely o convert firmware.sh to C o symlink names to udevadm will no longer be resolved to old command names o "udevadm control" commands will only accept the -- syntax o drop all support for the DEPRECATED sysfs layout o add warning for BUS, SYSFS, ID
