+Exercise the wallet backup code.  Ported from walletbackup.sh.
+
+Test case is:
+4 nodes. 1 2 and 3 send transactions between each other,
+fourth node is a miner.
+1 2 3 each mine a block to start, then
+Miner creates 100 blocks so 1 2 3 each have 50 mature
+coins to spend.
+Then 5 iterations of 1/2/3 sending coins amongst
+themselves to get transactions in the wallets,
+and the miner mining one block.
+
+Wallets are backed up using dumpwallet/backupwallet.
+Then 5 more iterations of transactions and mining a block.
+
+Miner then generates 101 more blocks, so any
+transaction fees paid mature.
+
+Sanity check:
+  Sum(1,2,3,4 balances) == 114*50
+
+1/2/3 are shutdown, and their wallets erased.
+Then restore using wallet.dat backup. And
+confirm 1/2/3/4 balances are same as before.
+
+Shutdown again, restore using importwallet,
+and confirm again balances are correct.
