udev: Rearrange the udev files into a more logical structure. Create copies of the rules we're using rather than the distributed version due to links to external scripts. Add mount.sh which attempts to mount block devices using pmount if available, falling back to mount if not. Fix the --mode switch to mknod in the init script.
