Log message:
	Const fixing
	
	Fixing some const warnings - with API change in:
	
	int vg_extend(struct volume_group *vg, int pv_count, const char *const *pv_names,
	
	Change is needed - as lvm2api expects const behaviour here.
	So vg_extend() is doing local strdup for unescaping.
	
	skip_dev_dir return const char* from const char* vg_name.
	
	Rest of the patch is cleanup of related warnings.
	
	Also using dm_report_filed_string() API change to simplify
	casting in _string_disp and _lvname_disp.
