Test prioritisetransaction
After talking with @str4d about #1884 , I wrote a test for prioritisetransaction. It uses small blocks (11kb), and checks whether a transaction makes it into the next block after being prioritized by that node.
Should this be improved with a larger number of txs in the mempool, or by testing over multiple runs?
As for getblocktemplate(), it seems to return the prioritized transaction within the block size set by the node (about 50 txs fit in an 11kb block), but the block "sizelimit" it displays is set at 2 MB in `rpcmining.cpp` line 690:
```
result.push_back(Pair("sizelimit", (int64_t)MAX_BLOCK_SIZE));
```
This was quite confusing, I didn't think the `-blockmaxsize` parameter I was setting was working for awhile.
Closes#2113. Fixes bug in test and updates testnet fr addresses.
Updating the testnet fr addresses will introduce a consensus change on testnet, so all testnet nodes will be required to upgrade. See #2113 for more information.
Closes#2112 where z_getoperationresult could return stale status.
The problem was similar to a check-then-act race condition. Status object was obtained from an operation, which might be in an 'executing' state. Instead of checking the state recorded in the status object, the operation was queried again to see if it was in a finished state (failed,success,cancelled) and if yes, the status object was returned to the user. However, if the operation had changed state in the background, the status object would be stale.
Sets default min relay tx fee to 100, which is used to initialize
nSatoshisPerK for min fee calculation. The default z_sendmany
fee of 10000 is now sufficient to cover a tx of size 100000 bytes,
so txs will not be treated as "free" and hit the free rate limiter.
