9cbe4c1af9 log_info to log_very_verbose 
Translate log_info() into log_very_verbose() which is macro
supposed to be used by our code.

log_info() is internal macro with eventually some 'symbolic' meaning
in syslogging daemons.

4b4d19e3aa dmeventd: separate dm and dmeventd logging 
Ensure different logging function for dmeventd.c logging
and dm and lvm library.

We can recognize we want to show every log_info() and
log_notice() message from dmeventd.c code while not
exposing those from libdm/libdevmapper-event

Also switch to use log with errno - it's not changing
anything and doesn't bring any more features yet to dmeventd
logging but we just properly pass dm_errno_or_class properly
through the whole code stack for possible future use
(i.e. support of class logging for dmeventd).

ee04f1fcfd raid: dmeventd plugin use 64bit arithmetic 
Coverity suggested to used 64bit unsigned ints instead of signed 32b int.
Assuming there is no user of >31legs raid array.

5d455b28fc lvconvert: fix (automatic) raid repair regression 
The dm-raid target now rejects device rebuild requests during ongoing
resynchronization thus causing 'lvconvert --repair ...' to fail with
a kernel error message. This regresses with respect to failing automatic
repair via the dmeventd RAID plugin in case raid_fault_policy="allocate"
is configured in lvm.conf as well.

Previously allowing such repair request required cancelling the
resynchronization of any still accessible DataLVs, hence reasoning
potential data loss.

Patch allows the resynchronization of still accessible DataLVs to
finish up by rejecting any 'lvconvert --repair ...'.

It enhances the dmeventd RAID plugin to be able to automatically repair
by postponing the repair after synchronization ended.

More tests are added to lvconvert-rebuild-raid.sh to cover single
and multiple DataLV failure cases for the different RAID levels.

2f638e07e8 dmeventd: thin plugin umount over 95% 
Run umount code only when either thin data or metadata are
above 95% - so if there are resize failures with 60%.
system fill keep running.

Also umount will only be tried with lvm2 LVs.
Foreign users are ATM unsuppored.

099466939e thin: dmeventd plugin check number of failures 
If plugin's lvm command execution fails too often (>10 times),
there is no point to torture system more then necessary, just log

a6d1c8ac65 dmeventd: use matching function 
Respect lvm2_log_fn prototype. The idea of 'reusing' print_log with
plain cast is causing very strange crashes with some older 'gcc'  compilers.
So just do it cleanly...
