Not ready to merge yet. I've tested this with a -salvagewallet loop: Even though reporting is better, it still hangs after "Stopping nodes", going to investigate why. |

Should be fixed now. The problem was that start_nodes can fail with part of the nodes already started. |
Replace the `bitcoin-cli -rpcwait` after spawning bitcoind with our own loop that detects when bitcoind exits prematurely. And if one node fails to start, stop the others. This prevents a hang in such a case (see bitcoin#7463).

Nit: rpcbind_test.py no longer works after this.

We should probably re-add that test to one of the standard sequence, otherwise it will just bitrot

This is a merge of bitcoin/bitcoin#7744 / MVF-Core PR#16. Instead of freezing up qa tests, wallet.py will fail on some 32-bit platforms where wallet salvage operation sometimes fails due to unknown reasons. See also: bitcoin/bitcoin#7463 about the -salvagewallet problem. Core has decided to disable the salvage part of the test in bitcoin/bitcoin#8038 , we may implement a Skip() of this test on 32-bit or disable that test step in a similar way. The wallet salvage problem is definitely unrelated to any fork programming.
