55d83f9f6e mirror: block_on_error only with monitoring
When user configured lvm2 to NOT user monitoring, activated mirror
actually hang upon error and it's quite unusable moment.

So instead Warn those 'brave' non-monitoring users about possible
problem and activation mirror without blocking error handling.

This also makes it a bit simpler for test suite to handle trouble
cases when test is running without  dmeventd.

66400d003d mirror: fix region_size for clustered VG
When adjusting region size for clustered VG it always needs to fit
2 full bitset into 1MB due to old limits of CPG.

This is relatively big amount of bits, but we have still limitation
for region size to fit into 32bits (0x8000000).

So for too big mirrors this operation needs to fail - so whenever
function returns now 0, it means we can't find matching region_size.

Since return 0 is now 'error' we need to also pass proper region_size
when creating pvmove mirror.

a19456b868 mirror: fix calcs for maximal region_size
Since extent_size is no longer power_of_2 this max region size
evalution was rather producing random bitsize as a combination
of lowest bit from number of extents and extent size itself.

Correct calculation to use whole LV size and pick biggest
possible power of 2 value smaller then UINT32_MAX.

91965af9b1 mirror: improve mirror log size estimation
Drop mirrored mirror log limitation that applies only in very limited
use-case and actually mirrored mirror log is deprecated anyway.

So 'disk' mirror log is selecting the correct minimal size, and
bigger size is only enforced with real mirrored mirror log.

Also for mirrored mirror log we let use 'smalled' region size if needed
so if user uses  1G region size, we still keep small mirror log
with much smaller region size in this case when needed.

Also mirror log extent calculation is now properly detecting error
with too big mirrors where previosly trimmed uint32_t was applies
unintentionally.

ff3ffe30e4 activation: add generic rule for visibility change

processing as well as ensure content of dm table is correct.

7a7b8a7778 udev: keep systemd vars on change event in 69-dm-lvm-metad.rules for systemd reload
The current logic that avoids setting SYSTEMD_ALIAS and SYSTEMD_WANTS
on "change" events is flawed in the default "systemd background job"
configuration. For systemd, it's important that device properties don't
change spuriously.

If an "add" event starts lvm2-pvscan@.service for a device, and a
"change" event follows, removing SYSTEMD_ALIAS and SYSTEMD_WANTS from the
udev db, information about unit dependencies between the device and the
pvscan service can be lost in systemd, in particular if the daemon
configuration is reloaded.

Steps to reproduce problem:

- create a device with an LVM PV
- remove device
- add device (generates "add" and "change" uevents for the device)
  (at this point SYSTEMD_ALIAS and SYSTEMD_WANTS are clear in udev db)
- systemctl daemon-reload
  (systemd reloads udev db)
- vgchange -a n
- remove device

=> the lvm2-pvscan@.service for the device is still active although the
device is gone.

- add device again

=> the PV is not detected, because systemd sees the lvm2-pvscan@.service
as active and thus doesn't restart it.

The original purpose of this logic was to avoid volumes being scanned
over and over again. With systemd background jobs, that isn't necessary,
because systemd will not restart the job as long as it's active.

99bfbbf229 udev: explicit pvscan rule in 69-dm-lvm-metad.rules
Make the distinction between the cases with and without systemd
background jobs explicit in 69-dm-lvm-metad.rules rather than
substituting the rule from the Makefile. At this stage,
this improves only readibility, at the cost of one GOTO statement.

This patch introduces no functional change to the udev rules.
