Refactor snapshot-merge deptree and device removal to support info-by-uuid

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.

lvconvert --merge @tag support

Switch lvconvert's --merge code over to using process_each_lv().  Doing
so adds support for a single 'lvconvert --merge' to start merging
multiple LVs (which includes @tag expansion).

Add 'lvconvert --merge @tag' testing to test/t-snapshot-merge.sh

Adjust man/lvconvert.8.in to reflect these expanded capabilities.

The lvconvert.c implementation requires rereading the VG each iteration
of process_each_lv().  Otherwise a stale VG instance associated with
the LV passed to lvconvert_single_merge() would result in stale VG
metadata being written back out to disk.  This overwrote new metadata
that was written when a previous snapshot LV finished merging (via
lvconvert_poll).  This is only an issue when merging multiple LVs that
share the same VG (a single VG is typical for most LVM configurations on
system disks).

In the end this new support is very useful for performing a "system
rollback" that requires multiple snapshot LVs be merged to their
respective origin LV.

The yum-utils 'fs-snapshot' plugin tags all snapshot LVs that it creates
with a common 'snapshot_tag' that is unique to the yum transaction.
Rolling back a yum transaction, that created LVM snapshots with the tag
'yum_20100129133223', is as simple as:
  lvconvert --merge @yum_20100129133223

Adding a new mimage (leg/copy) to a mirror behaves differently
depending on if the mirror has a 'core' or 'disk' log.  When there
is a disk log, the new leg is added by stacking a new mirror on
top of the old (one leg is the old mirror and the other leg is the newly
added device).  When the log is a 'core' log, the new leg is simply added
to the existing mirror and all the devices are re-synced.

The logic that handles collapsing the stacked 'disk' log mirror was
having the effect of causing 'core' logged mirrors to begin resync'ing
for a second time.  I have used the 'CONVERTING' flag to indicate that
a mirror is converting by way of stacking.  This is no longer set for
up-converting core logs.  The final 'collapse' logic can safely be skipped
