Modified files:
	tools          : vgsplit.c 

Log message:
	Change vgsplit behavior to open/lock first vg based on alphabetical ordering.
	
	If the destination vgname comes before the source vgname, we must open the
	destination first because of the locking rules.  Thus, do a strcmp and set
	the flag based on the comparison.
