34caf83172 lvconvert: add infrastructure for RaidLV reshaping support
In order to support striped raid5/6/10 LV reshaping (change
of LV type, stripesize or number of legs), this patch
introduces the changes to call the reshaping infratructure
from lv_raid_convert().

Changes:
- add reshaping calls from lv_raid_convert()
- add command definitons for reshaping to tools/command-lines.in
- fix raid_rimage_extents()
- add 2 new test scripts lvconvert-raid-reshape-linear_to_striped.sh
  and lvconvert-raid-reshape-striped_to_linear.sh to test
  the linear <-> striped multi-step conversions
- add lvconvert-raid-reshape.sh reshaping tests
- enhance lvconvert-raid-takeover.sh with new raid10 tests

aa72caca5a tests: support zero_dev
When the test would need to try to write some large amount of data
we can give it 'zero' segments - for obvious reason such written data
can't be verified but in some test cases it doesn't really matter.

Usage follows  'error_dev' style.

For now test suite is not supporting any combination of
error/delay/zero segments so only 1 type could be used per PV.

55eaabd118 lvreduce/lvresize: add ability to reduce the size of a RaidLV
- support shrinking of raid0/1/4/5/6/10 LVs
- enhance lvresize-raid.sh tests: add raid0* and raid10
- fix have_raid4 in aux.sh to allow lv_resize-raid.sh
  and other scripts to test raid4

b92a9c3e1a tests: slow down devs for raid more
Since we still experience occasiaonal test failure - slow
things down even more to avoid race.

b38564b8dc tests: do not set zero interval in aux lvm.conf

Avoid testing this patological case.

d2c3b23e6d lvchange: Allow device specification when requesting a repair
'lvchange --resync LV' or 'lvchange --syncaction repair LV' request the
RAID layout specific parity blocks in raid4/5/6 to be recreated or the
mirrored blocks to be copied again from the master leg/copy for raid1/10,
thus not allowing a rebuild of a particular PV.

Introduce repeatable option '--[raid]rebuild PV' to allow to request
rebuilds of specific PVs in a RaidLV which are known to contain corrupt
data (e.g. rebuild a raid1 master leg).

Add test lvchange-rebuild-raid.sh to test/shell doing rebuild
variations on raid1/10 and 5; add aux function check_status_chars
to support the new test.

2981d1e798 tests: try to force remove higher minor first
When force removing thin-pool we loose 'real' access to hidden device,
and if such pool is in suspended state, any thin volume cannot be
dropped. It likely should be also checked by dmsetup, but meanwhile
apply simple logic -  try to force remove first all higher minors first
with assumption we first create thin-pool and then thin volume
and there are usually not being released lower dm numbers to
get the order wrong.

07c1694ff5 tests: update aux raid support
For raid1  use chunksize as bitmap-chunk specification.
Always enforce usage of bitmap - getting comparable outcome
as lvm2 raid support uses.
Add udev_wait after stopping  md array - as in fact leg-device
are still in use by target even command has finished.

(mdadm --stop causes WATCH rule wakeup, and
ioctl(STOP_ARRAY) returns IMHO to early - it should finish
and fsync work on leg devices first).

Rather then skipping whole test - just do not use it.

Failing tests that have required delay need to deal with reality
and shell either check for HAVE_DM_DELAY and skip portion
of test or using should when needed.
