Regression tests of RPC interface

Bash scripts that use the RPC interface and command-line bitcoin-cli to test full functionality in -regtest mode.

wallet.sh : Exercise wallet send/receive code.

txnmall.sh : Test proper accounting of malleable transactions

conflictedbalance.sh : More testing of malleable transaction handling

util.sh : useful re-usable bash functions

Tips for creating new tests

To cleanup after a failed or interrupted test: killall bitcoind rm -rf test.*

The most difficult part of writing reproducible tests is keeping multiple nodes in sync. See WaitBlocks, WaitPeers, and WaitMemPools for how other tests deal with this.
