and add severe warning if it's used to make a device seem bigger than

o First changes to add snapshot support.
...
I'm taking a different route from LVM1 here in that snapshots are a
seperate entity from the logical volumes, I think of them as an
application of an LV (or two lvs rather). As such there is a list of
snapshots held against the vg, and there is *not* a SNAPSHOT, or
SHAPSHOT_ORG flag in lv->status.
