2214dc12c3 lvconvert: reject conversions of LVs under snapshot
Conversions of LVs under snapshot to thinpool or cachepool
correctly fail but leave them inactive and provide cryptic
error messages like 'Internal error: #LVs (10) != #visible
LVs (2) + #snapshots (1) + #internal LVs (5) in VG VG'.

Reject and provide better error message.

8a66c81b9b lvconvert: restrict command matching for no option variant
The 'lvconvert LV' command def has caused multiple problems
for command matching because it matches the required options
of any lvconvert command.  Any lvconvert with incorrect options
ends up matching 'lvconvert LV', which then produces an error
about incorrect options being used for 'lvconvert LV'.  This
prevents suggestions from nearest-command partial command matches.

Add a special case for 'lvconvert LV' so that it won't be used
as a partial match for a command that has options specified.

117160b27e Remove lvmetad
Native disk scanning is now both reduced and
async/parallel, which makes it comparable in
performance (and often faster) when compared
to lvm using lvmetad.

Autoactivation now uses local temp files to record
online PVs, and no longer requires lvmetad.

There should be no apparent command-level change
in behavior.

db741e75a2 pvscan: autoactivate without lvmetad
When lvmetad is not used, use temporary files to record
which PVs have appeared.  Use these temp files to determine
when a VG is complete, to trigger autoactivation.

This change allows us to remove lvmetad while keeping the
same autoactivation behavior that lvmetad provides.

The temp files are created in /run/lvm/pvs_online/ and are
named for the PVID of the PV.  The files contain the
major:minor of the device the PV was read from.

e.g. if VG foo has dev1 and dev2, then:

. pvscan --cache -aay dev1
  reads vg metadata from dev1
  creates /run/lvm/pvs_online/<pvid-of-dev1>
  checks if all vg->pvs are online: no

. pvscan --cache -aay dev2
  reads vg metadata from dev2
  creates /run/lvm/pvs_online/<pvid-of-dev2>
  checks if all vg->pvs are online: yes
  autoactivates vg

A 'pvscan --cache dev' (without -aay) still records that
dev is online.

A 'pvscan --cache --major X --minor Y' after a device is
gone will remove the temp file for it.

A 'pvscan --cache [-aay]' (no devs) resets the state of
temp files by removing them all, then scanning all devs
and creating temp files for PVs that are found.

If no online files exist, the first pvscan --cache scans
all devs and creates temp files for any PVs found.

The scope of the temp files is only pvscan, and they are only
used for pvscan-based autoactivation.  No other commands are
concerned with or aware of these temp files.  When lvm creates
or removes PVs, no attempt is made to update the temp files.
