Add a merging snapshot to the deptree, using the "error" target, rather than avoid adding it entirely. This allows proper cleanup of the -cow device without having to rename the -cow to use the origin's name as a prefix. Move the preloading of the origin LV, after a merge, from lv_remove_single() to vg_remove_snapshot(). Having vg_remove_snapshot() preload the origin allows the -cow device to be released so that it can be removed via deactivate_lv(). lv_remove_single()'s deactivate_lv() reliably removes the -cow device because the associated snapshot LV, that is to be removed when a snapshot-merge completes, is always added to the deptree (and kernel -- via "error" target). Now when the snapshot LV is removed both the -cow and -real devices get removed using uuid rather than device name. This paves the way for us to switch over to info-by-uuid queries.
