/*-----------------------------------------------------------------------------
 * EvalVolumeSetOld
 *
 * Description:
 *	Takes the entries in a volumeset and expands them into a list of
 *      volumes. Every VLDB volume entry is looked at and compared to the
 *      volumeset entries.
 *
 *      When matching a VLDB volume entry to a volumeset entry,
 *       1. If the RW volume entry matches, that RW volume is used.
 *       2. Otherwise, if the BK volume entry matches, the BK volume is used.
 *       3. Finally, if the RO volume entry matches, the RO volume is used.
 *      For instance: A volumeset entry of ".* .* user.t.*" will match volume
 *                    "user.troy" and "user.troy.backup". The rules will use
 *                    the RW volume "user.troy".
 *
 *      When a VLDB volume entry matches a volumeset entry (be it RW, BK or RO),
 *      that volume is used and matches against any remaining volumeset entries
 *      are not even done.
 *      For instance: A 1st volumeset entry ".* .* .*.backup" will match with
 *                    "user.troy.backup". Its 2nd volumeset entry ".* .* .*"
 *                    would have matched its RW volume "user.troy", but the first
 *                    match is used and the second match isn't even done.
 *
 * Arguments:
 *	aconfig	: Global configuration info.
 *	avs	:
 *	avols	: Ptr to linked list of entries describing volumes to dump.
 *	uclient	: Ptr to Ubik client structure.
 *
 * Returns:
 *	0 on successful volume set evaluation,
 *	Lower-level codes otherwise.
 *
 * Environment:
 *	Expand only the single volume set provided (avs); don't go down its chain.
 *
 * Side Effects:
 *	None.
