9dfa6f3879 devices file: move clean up after command is run
devices_file_exit wasn't being called between lvm_shell
commands, so the file lock wouldn't be released.

7ec0726ce3 toollib: fix segfault when handling selection with historical LVs
When processing historical LVs inside process_each_lv_in_vg for
selection, we need to use dummy "_historical_lv" for select_match_lv.

This is because a historical LV is not an actual LV, but only a tiny
representation with subset of original properties that we recorded
(name, uuid...).

To use the same processing functions we use for full-fledged non-historical
LVs, we need to use the prefilled "_historical_lv" structure which has all
the other missing properties hard-coded.

494372b4ee filter-mpath: use multipath blacklist
Explicit wwid's from these sections control whether the
same wwid in /etc/multipath/wwids is recognized as a
multipath component.  Other non-wwid keywords are not
used, and may require disabling the use of the multipath
wwids file in lvm.conf.

151ce8b276 vgimportdevices: fix incorrect deviceidtype usage
When a VG has PVs with different device id types,
it would try to use the idtype of the previous PV
in the loop.  This would produce an unncessary warning,
or could lead to using the devname idtype when a better
idtype is available.

f840dbb320 pvscan: warn about /dev/sda excluded by devices file
In most installations, /dev/sda* or /dev/vda* should be included
in system.devices because the root, home, etc LVs are usually on
sda or vda.

Add a special case warning when a pvscan autoactivation command
sees that /dev/sda* or /dev/vda* are excluded by system.devices,
either not listed or having a different device id.

6e22be20c6 devices file: warn about missing multipath entry
Warn if a scsi device is listed in the devices file that
is used by a multipath device that is not listed.  This
will happen if a scsi device is listed in the devices
file and then an mpath device is set up to use it.

The way to correct this would be to remove the devices
file entry for the component device and add a new entry
for the multipath device.

f1578b4a5d Move nolocking warning to man page
It's more logical to warn about --nolocking in the man page
before it's used rather than after it's used and too late.
Also, warnings are usually for things the user may not know.

4eb04c8c05 devices: fix dev_name assumptions
dev_name(dev) returns "[unknown]" if there are no names
on dev->aliases.  It's meant mainly for log messages.

Many places assume a valid path name is returned, and
use it directly.  A caller that wants to use the path
from dev_name() must first check if the dev has any
paths with dm_list_empty(&dev->aliases).

00c3069872 devices: initial use of existing option
Use dev_cache_get_existing() in a few common, high level
locations where it's obvious that only existing dev-cache
entries are wanted.  This can be expanded and used in more
locations (or dev_cache_get can stop creating new entries.)

7e70041e32 devices: drop incorrect paths from aliases list
along with some basic checks for cases when a device
has no aliases.

lvm itself creates many situations where a struct device
has no valid paths, when it activates and opens an LV,
does something with it, e.g. zeroing, and then closes
and deactivates it.  (dev-cache is intended for PVs, and
the use of LVs should be moved out of dev-cache in a
future patch.)

c2679f76e5 dev_manager: failing status is not internal error

d59382c772 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.)
