"""
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.
