c2ed5feee5 systemid: Add warnings if invalid.
Add WARNING messages if there are problems setting the requested
system ID.
Ban "localhost" as a prefix regardless of the system_id_source.
Use cmd->hostname instead of calling uname again.
Make system_id_source values case-insensitive (as with new settings like
log_debug_classes) and also accept machine-id to match the filename.

2a1189ebc3 config: Reinstate recursive tags setting.
In 2.02.99, _init_tags() inadvertently began to ignore the
dm_config_tree struct passed to it.  "tags" sections are not
merged together, so the "tags" section in the main config file was
being processed repeatedly and other "tags" sections were ignored.

Dop unused value assignments.

Unknown is detected via other combination
(!linear && !striped).

Also change the log_error() message into a warning,
since the function is not really returning error,
but still keep the INTERNAL_ERROR.

Ret value is always set later.

ed420fb691 pvcreate: switch to "none" dev-ext source during pvcreate
The dev ext source must be reset for the dev_cache_get call
(which evaluates filters), not lvmcache_label_scan - so fix
original commit 727c7ff85d.

Also, add comments in _pvcreate_check fn explaining why
refresh filter and rescan is needed and exactly in which
situations.

69b1e32c8a wiping: blkid: do not count skipped signatures in final number of wipes
We exclude some signatures from being wiped when using blkid wiping.
These are signatures which we simply overwrite. For example, the
LVM2_member signature which denotes a PV - if we call pvcreate on
existing PV, we just overwrite the PV header, no need to wipe it.

Previously, we counted such signatures as if they were wiped
and they were counted in the final number of wiped signatures
that _wipe_known_signatures_with_blkid fn returned in the "wiped"
output arg. Then the code checking this output arg could be
mislead that wiping happened while no wiping took place in real
and we could fire some code uselessly based on this information
(e.g. refreshing filters/rescanning - see also
commit 6b4066585f).

6b4066585f filters: no need to refresh filters/rescan if no signature is wiped during pvcreate at all
Before, we refreshed filters and we did full rescan of devices if
we passed through wiping (wipe_known_signatures fn call). However,
this fn returns success even if no signatures were found and so
nothing was wiped. In this case, it's not necessary to do the
filter refresh/rescan of devices as nothing changed clearly.

This patch exports number of wiped signatures from all the
wiping functions below. The caller (_pvcreate_check) then checks
whether any wiping was done at all and if not, no refresh/rescan
is done, saving some time and resources.

727c7ff85d pvcreate: switch to "none" dev-ext source during pvcreate
pvcreate code path executes signature wiping if there are any signatures
found on device to prepare the device for PV. When the signature is wiped,
the WATCH udev rule triggers the event which then updates udev database
with fresh info, clearing the old record about previous signature.

However, when we're using udev db as dev-ext source, we'd need to wait
for this WATCH-triggered event. But we can't synchronize against such
events (at least not at this moment). Without this sync, if the code
continues, the device could still be marked as containing the old
signature if reading udev db. This may end up even with the device
to be still filtered, though the signature is already wiped.

This problem is then exposed as (an example with md components):

$  mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sda /dev/sdb --run
$  mdadm -S /dev/md0
$  pvcreate -y /dev/sda
Wiping linux_raid_member signature on /dev/sda.
/dev/sda: Couldn't find device.  Check your filters?
$ echo $?
5

So we need to temporarily switch off "udev" dev-ext source here
in this part of pvcreate code until we find a way how to sync
with WATCH events.

(This problem does not occur with signature wiping which we do
on newly created LVs since we already handle this properly with
our udev flags - the LV_NOSCAN/LV_TEMPORARY flag. But we can't use
this technique for non-dm devices to keep WATCH rule under control.)
