Add ability for node to reject tx from mempool by number of tx inputs
Implement short-term solution described in #2343 so that users can respond promptly to critical short-term problems caused by quadratic validation scaling, such as the getblocktemplate latency, block propagation latency, and mempool size inflation issues described in #2333.
Benchmark for calling ConnectBlock on a block with many inputs
Requires placing `block-107134.tar.gz` (containing the block, and a fake CoinsDB containing its inputs) into the base directory of the repository.
To facilitate generation of the fake CoinsDB, an additional field `valuesZat` has been added to `getrawtransaction` containing the integer number of zatoshis instead of a decimal number of ZEC.
Closes#2355.

Usability improvements for z_importkey
- Add height parameter to z_importkey to reduce rescan range
- Change semantics of rescan parameter, so users can explicitly force a rescan
for existing keys.
Closes#2032
Python's httplib does not graciously handle disconnections from the http server, resulting in BadStatusLine errors.
See https://bugs.python.org/issue3566 "httplib persistent connections violate MUST in RFC2616 sec 8.1.4."
This was fixed in Python 3.5.
Work around it for now.
This reverts commit bd30c3dced21fca869a14c75081f15195762afe1.
Disable windows RPC tests for now. These should be re-enabled once a
suitable Wine version is used on Travis.

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).

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`.
