5ba2d58d28 activation: improve error handling for status reading
When lvm2 wants to see a status, it needs to validate,
segment for status reading is matching whan lvm2 expects in
metadata.

Also ensure status failure will not cause '0' from info reading
when actual info was collected properly.
Failure in 'status' reading is considered to be
a 'log_warn()' event only.

4a4b22e114 activation: status check switch to warn
When we can't parse status, switch to warning as this is not
considered an errornous case.  LVS is not supposed to return
error status code when  device is not what it's been expected to
be - but it should be WARNING a user there is something unexpected.

254f73e3ef snapshot: reporting uses statusinfo
Convert lvs -o lv_merge_failed,lv_snapshot_invalid to use
lv_info_and_status function.

This makes it equal to attr value showing this info
(as they were different since they were derived from
different data set and different logic as well).

Also saves couple extra ioctl that were needed to obtain this info.

07f9889b53 report: order fields by type for field defintions in columns.h
When displaying <reporting_command> -o help, we'd like to have fields
grouped nicely, not starting having groups interleaved as it was before.
The code that displays the help output for fields takes the order as
written in columns.h file - this caused output like:

$ lvs -o help

Logical Volume Fields
---------------------
...field list...

Logical Volume Device Info and Status Combined Fields
-----------------------------------------------------
...field list...

Logical Volume Fields
---------------------
...field list...

Logical Volume Device Status Fields
-----------------------------------
...field list...

Logical Volume Fields
---------------------
...field list...

Instead, let's have it without groups interleaved which may be
a bit confusing, so:

Logical Volume Fields
---------------------
...field list...

Logical Volume Device Status Fields
-----------------------------------
...field list...

Logical Volume Device Info and Status Combined Fields
-----------------------------------------------------
...field list...

..and so on.

ad7fd775f2 lvmdbustest.py: Rename env test variable
Use LVM_DBUSD_TEST_MODE env variable to customize what we test.
Default is the same where we try to test all combinations of all
modes.  Renamed to make it consistent with the other env variables
that are used in the unit test.

0b8bf73a63 lvchange: allow a transiently failed RaidLV to be refreshed
In case any SubLV of a RaidLV transiently fails, it needs
two "lvchange --refresh RaidLV" runs to get it to fully
operational mode again.  Reason being, that lvm reloads all
targets for the RaidLV tree but doesn't resume the SubLVs
until after the whole tree has been reloaded in the first
refresh run.  Thus the live mapping table of the SubLVs
still point to an "error" mapping and the dm-raid target
can't retrieve any superblock from the MetaLV(s) in processing
the constructor during this preload thus not discovering the
again accessible SubLVs.  In the second run, the SubLV targets
map proper (meta)data, hence the constructor discovers those
fine now.

Solve by resuming the SubLVs of the RaidLV before
preloading the respective top-level RaidLV target.
