This delegates node creation to udev. Among other things, the
important advantage of this approach is population of all the related
stuff in /dev/disk/by-* ; relying on udev can also be controlled
through dmsetup's command line
Comments related to this version:
- another minor patch for static build scenario had to be applied;
hopefully it will be fixed in upstream one day
- example users' file is installed in /etc/udev/rules.d (not active)
- configure is now consistent with lvm2 (they can be trivially merged
into single package now)
- minor adjustment to .pc
