Subject: [PATCH] devices file: do not clear PVID of unread devices
In a certain disconnected state, a block device is present on
the system, can be opened, reports a valid size, reports the
correct device id (wwid), and matches a devices file entry.
But, reading the device can still fail. In this case,
device_ids_validate() was misinterpreting the read error as
the device having no data/label on it (and no PVID).
The validate function would then clear the PVID from the
devices file entry for the device, thinking that it was
fixing the devices file (making it consistent with the on disk
state.) Fix this by not attempting to check and correct a
devices file entry that cannot be read. Also make this case
explicit in the hints validation code (which was doing the
right thing but indirectly.)

Subject: [PATCH 2/7] devices file: fail if --devicesfile filename doesn't
exist
A typo of the filename after --devicesfile should result in a
command error rather than the command falling back to using no
devices file at all. Exception is vgcreate|pvcreate which
create a new devices file if the file name doesn't exist.

Subject: [PATCH 4/7] filter-mpath: get wwids from sysfs vpd_pg83
to compare with wwids in /etc/multipath/wwids when
excluding multipath components. The wwid printed
from the sysfs wwid file may not be the wwid used
in multipath wwids. Save the wwids found for each
device on dev->wwids to avoid repeating reading
and parsing the sysfs files.

Subject: [PATCH 5/7] pvdisplay: restore --reportformat option
Fixes commit b8f4ec846 "display: ignore --reportformat"
by restoring the --reportformat option to pvdisplay.
Adding -C to pvdisplay turns the command into a reporting
command (like pvs, vgs, lvs) in which --reportformat can
be useful.
(cherry picked from commit db5277c97155632ce83e1125e348eda97c871968)
