Fix issue preventing cluster mirror creation.

Mirrors used to be created by first creating a linear device and then adding
the other images plus the log.  Now mirrors are created by creating all the
images in one go and then adding the log separately.  The new way ran into
the condition that cluster mirrors cannot change the log type (in the case
of creation, from core -> disk) while the mirror is not active.  (It isn't
active because it is in the process of being created.)  The reason this
condition is in place is because a remote node may have the mirror active, and
we don't want to alter the log underneath it.

What we really needed was a way of checking if the mirror was active remotely
but not locally, and in that case do not allow a change of the log.  I've added

Fix create_temp_name to replace any '/' found in the hostname with '?'.

There's a possibility someone will use the '/' in the hostname. Since we
generate a temporary file name (path) including the hostname, any '/' would
be ambiguous.

We can always set such hostname using 'sethostname' from unistd.h. But the
'hostname' command already includes the check and removes the '/' char.
However, some old versions still allow that.
See: https://bugzilla.redhat.com/show_bug.cgi?id=711445.

Since this is only a temporary name and the possibility of this error is
quite negligible, we don't need any complex escape sequence here, just a
simple char replace.

Use new dev_open_readonly fn to prevent opening devices for read-write when not necessary.

Before, we used vg_write_lock_held call to determnine the way a device is
opened. Unfortunately, this opened many devices in RW mode when it was not
really necessary. With the OPTIONS+="watch" rule used in the udev rules,
this could fire numerous events while closing such devices (and it caused
useless scans from within udev rules in return).

patch should minimize such situations (at least with respect to LVM handling
