Update udev initscript

The init script for udev-115 (and now 118) is simply the script for udev-100
copied over.  While I can't vouch for how well that worked for that version,
for newer versions, the script is now very suboptimal.  I've tested the
attached with both 115 and 118.

This is based upon reading what Ubuntu 7 does, which ships udev-113.  There's a
lot of changes here, so:
- Cosmetic: Name our mount udev not tmpfs.
- Actually create /dev/null before starting udevd
- Bump min kernel to 2.6.15 for uevent
- No more set_hotplug_handler, warn_if_interactive
- udev_root, udevd_timeout are gone.
- Mount check wasn't working at all, and didn't make sense.
- Do things that claim to need to be done before starting udevd, before we
start udevd
- We don't need to mkdir things udevd will make for us
- udevsettle does that whole wait thing for us.
