activated. One can define the list of VGs directly to do that. But that

dev-io: open device read-only to obtain readahead value

There's no need to have the device open RW while obtaining the readahead value.
The RW open used before caused the CHANGE udev event to be generated if the
WATCH udev rule was set for the underlying device (and that is normally the
case both for non-dm and dm devices by default).

This did not cause any problems before since we were not interested in
*underlying* devices. However, with upcoming changes (autoactivation), we're
watching for events on underlying devices marked as PVs and such a spurious
event could cause the autoactivation code to be triggered. So when trying
to deactivate the volume, we could end up with immediate activation just after
that because of the CHANGE event originated in the WATCH udev rule since the
underlying device was open RW during the deactivation process.

Though maybe a better solution would be to completely filter such spurious
events out of the autoactivation process somehow, it's still useful if there
are as least spurious events generated as possible in the system itself.

Fix up-convert when mirror activation is controled by volume_list and tags.

When mirrors are up-converted, a transient mirror layer is put in so that
only the new devices are sync'ed.  That transient layer must carry the tags
of the original mirror LV, otherwise it will fail to activate when activation
is regulated by lvm.conf:activation/volume_list.  The conversion would then
fail.

mirror converting (lib/metadata/mirror.c:_init_mirror_log()).  We copy the
tags temporarily for the new LV and remove them after the activation.
