Merge the haad-dm branch to -current. This branch adds LVM functionality to the base NetBSD system. It uses Linux LVM2 tools and our BSD licensed device-mapper driver. The device-mapper driver can be used to create virtual block devices which maps virtual blocks to real with target mapping called target. Currently these targets are available a linear, zero, error and a snapshot (this is work in progress and doesn't work yet). The lvm2tools adds lvm and dmsetup binary to based system, where the lvm tool is used to manage and administer whole LVM and the dmestup is used to communicate iwith device-mapper kernel driver. With these tools also a libdevmapper library is instaled to the base system. Building of tools and driver is currently disable and can be enabled with MKLVM=yes in mk.conf. I will add sets lists and rc.d script soon. Oked by agc@ and cube@.

Important unimplemented features in current device-mapper implementation
* implement dm_dev_event_ioctl and dm_target_msg_ioctl functions
* write more targets mirror, stripe.
* snapshot target, there is some code in repository already
Remove done task and add new one.

* integrate LVM with sysinst, so we can configure LVM during installation

Pain in the sky tasks
* implement multipath target for network attached storage devices.
* Cluster lvm extension, NetBSD needs Distributed Lock Manager for this.
* write GPL free libdevmapper and lvm2tools.
