Modified files:
	tools          : reporter.c 

Log message:
	The _free_vg that is created as a placeholder when reporting segments in pvs
	was lacking the (vgmem) pool. We now create that pool. There is at least one
	more such VG (_dummy_vg) which is pool-less. I am not sure what is the right
	way to go about this, but this is currently necessary to fix a segfault
	introduced by using vgmem in the reporter in Dave's lvseg lvm2app patches.
