0cbb381e15 lvcreate: regression fix on lv name limits
When we are given an existing LV name - it needs to be allowed
to pass in even restricted name as the LV could have existed
long before we introduced some new restriction on prefix/suffix.i

Fix the regression on name limits and drop restriction to be applied
on any existing LVs - only the new created LV names have to be
complient with current name restrictions.

FIXME: we are currently using restricted names incorrectly in few
other places - device_is_usable() skips restricted names,
and udev flags are also incorrectly set for restricted names
so these LVs are not getting links properly.

888da17495 metadata: add internal error if PV has no existing device attached during find_pv_in_vg
find_pv_in_vg fn iterates over the list of PVs covered by the VG and
each PV's pvl->pv->dev is compared with device acquired from device
cache. However, in case pvl->pv->dev is NULL as well as device cache
returns NULL (e.g. when device is filtered), we'll get incorrect match
and the code calling find_pv_in_vg uses incorrect PV (as it thinks
it's the exact PV with the pv_name). The INTERNAL_ERROR covers this
situation and errors out immediately.

8dc5f42254 metadata: Use flags to control warnings.
The warnings arg was used to enable logging of warnings
when reading a PV.  This arg is turned into a set of flags
with the WARN_PV_READ flag matching the existing behavior.

A new flag WARN_INCONSISTENT is added that will cause
vg_read_internal() to log the "VG is not consistent"
warning so the various callers do not need to log
this warning themselves.

A new vg_read flag READ_WARN_INCONSISTENT is used from
reporting to enable the WARN_INCONSISTENT flag in
vg_read_internal.

f1a000a477 toollib: Rewrite process_each_pv.

devices if the command needs to process non-PV devices.

d46c2f1c94 cache: improve creation code
Move code to better locations.
Improve test and remove invalid ones
(i.e. no reason to require cache size to be >= then origin).

Correctly comment where the code is doing actual conversion
of other existing volume - we do already a similar thing with
external origins.

Lots of new command line options and combinations is now supported.
Hopefully older syntax still works as well.

lvcreate --cache --cachepool vg/pool  -l1
lvcreate --type cache --cachepool vg/pool  -l1
lvcreate --type cache-pool vg/pool  -l1
lvcreate --type cache-pool --name pool vg  -l1
... and many many more ...

cb273fe164 pools: move removal of _pmspare
