Version 2.02.27 -
================================
Add pv_read_path external library function.
Turn _add_pv_to_vg() into external library function add_pv_to_vg().
Add pv_read_path() external library function.
Tidy clvmd-openais of redundant bits, and improve an error report.
Cope with find_seg_by_le() failure in check_lv_segments().
Call dev_iter_destroy() if _process_all_devs() is interrupted by sigint.
