Changes by:	wysochanski at sourceware.org	2010-09-30 14:07:48

Modified files:
	lib/metadata   : lv.c lv.h pv.c pv.h vg.c vg.h 
	liblvm         : lvm_lv.c lvm_pv.c lvm_vg.c 

Log message:
	Add pv_uuid_dup, vg_uuid_dup, and lv_uuid_dup, and call id_format_and_copy.
	
	Add supporting functions for pv_uuid, vg_uuid, and lv_uuid.
	Call new function id_format_and_copy.  Use 'const' where appropriate.
	Add "_dup" suffix to indicate memory is being allocated.
	Call {pv|vg|lv}_uuid_dup from lvm2app uuid functions.
