JSON makes no distinction between numbers and reals, and our code
doesn't need to do so either.
This removes VREAL, as well as its specific post-processing in
`UniValue::write`. Non-monetary amounts do not need to be forcibly
formatted with 8 decimals, so the extra roundtrip was unnecessary
(and potentially loses precision).
Zcash: cherry-picked from commit 7650449a6777710cf818d41862626164da0cd412

Since unspendable outputs can't be spent, there is no threshold at which it would be uneconomic to spend them.
This primarily targets transaction outputs with `OP_RETURN`.

Changes:
- cherry-picked on top of bitcoin:master
- added RPC test for fundrawtransaction
I've never liked the chain-specific exception to having to set a
password. It gives issues with #6388 which makes it valid to
set no password in every case (as it enables random cookie authentication).
This pull removes the flag, so that all chains are regarded the same.
It also removes the username==password test, which doesn't provide any
substantial extra security.
request object before returning an error so that id value can
be used in the response.
Prior to this commit, RPC commands sent during Bitcoin's
warmup/startup phase were responded to with a JSON-RPC error
with an id of null, which violated the JSON-RPC 2.0 spec:
id: This member is REQUIRED. It MUST be the same as the value
of the id member in the Request Object. If there was an error
in detecting the id in the Request object (e.g. Parse
error/Invalid Request), it MUST be Null.
For leveldb "An iterator operates on a snapshot of the database taken
when the iterator is created". This means that it is unnecessary to
lock out other threads while computing statistics, and neither to hold
cs_main for the whole time. Let the thread run free.
Univalue's parsing of \u escape sequences did not handle NUL characters
correctly. They were, effectively, dropped. The extended test-case
fails with the old code, and is fixed with this patch.
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.
