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.

haad | branches: 1.1.2;
Add dmgetdefaultdisklabel to get virtual disklabel for Logical Volume device. Add snapshot targets (snapshot, snapshot-origin), add dm_type to dm_dev structure to identify type of device. e.g. we can have mirrored disk device with snapshot on them and spare disk on them. When driver want to work with snapshot devices, it looks to upcalls list and finds all DM_SNAPSHOT devices.

haad | Import of device-mapper driver. This driver is BSD rewrite of linux dm driver.
For now only error, linear and zero targets are supported. This driver uses NetBSD
specific ioctl protocola based on proplib.
I was able to create logical volume (with lvm2tools lvcreate utility) with this
version of driver, newfs it and mount it.
