Log message:
	Add proper udev library context initialization and finalization to liblvm.
	
	This was missing in liblvm and it caused all udev-related operations to
	not take effect when using liblvm, e.g. obtaining the list of devices from udev
	db instead of scanning the whole /dev which also recreated the .cache as a side
	effect. This was also the case with udisks-lvm-pv-export prober which is run
	from within udev rules whenever the CHANGE event is fired.

 Version 2.02.86 -  
 =================================
+  Add proper udev library context initialization and finalization to liblvm.
   Fix last snapshot removal to avoid table reload while a device is suspended.
   Use dm_get_suspended_counter in replacement critical_section logic.
   Downgrade critical_section errors to debug level until it is moved to libdm.
