	                 lvm_vg.c 

Log message:
	Add most all liblvm 'get' functions needed for anaconda.
	
	Add the most straightforward 'get' functions required for anaconda.
	These are the ones that return simple uint64_t values.
	The other more complex ones involve the lv_attr bits.  These will
	come in a separate patch series since each lv_attr bit will be returned
	in a separate API instred of returning the string and requiring the
	user to parse it.
