Need to resurrect /lib/udev/devices handling with udev >= 183

[Bryan Kadzban]

Cherrypicking a random post from the linux-hotplug discussion:

udevd will no longer copy the contents of /lib/udev/devices into /dev at startup like it used to, and for which functionality we ripped out the copying from the udev bootscript. SIGH.

Dependent on #3098 being fixed first, since udev-182 works fine (and I suspect requires the current-bootscript behavior, though I don't know that for sure).

(Here's hoping nothing else has been silently dropped...)

Filing this so I don't forget about it before the next release.

I fixed this in mountvirtfs, but we need to make sure /lib/udev/devices has both:

crw-rw-rw- 1 root root 1, 3 May 15 02:24 null
drwxr-xr-x 2 root root 4096 May 15 02:24 pts

Closing as fixed in revision 9868, but above needs to addressed when we fix #3098.
