Modified files:
	liblvm         : lvm.h lvm_vg.c 

Log message:
	Update lvm_vg_create to use NULL / non-NULL return for the time being.
	
	Some of the error interface is still TBD.  Rather than exporting a lot
	of codes, etc, just use a simple pass / fail.  The allows our unit test
	to not segfault if trying to create a VG that already exists.
