[lvm-devel] [PATCH 10/20] Add supporting functions vg_name_dup, vg_fmt_dup, vg_system_id_dup.

[Dave Wysochanski]

Add supporting functions for vg_name, vg_fmt, vg_system_id.
Append "_dup" to end of supporting functions to make clear the strings
are dup'd and to avoid namespace conflict with vg_name.
