Version 2.02.26 -
=================================
+ Convert find_pv_in_vg_by_uuid and pv_create to use PV handles.
Add get_pv_* functions to return PV members (external LVM library).
Add wrappers to some functions in preparation for external LVM library.
Allow vgcfgrestore to list metadata backup files using -f
