7d263571bee8c36fbe3c854b69c6f31cf1ee3b9b rpc: require second argument only for scantxoutset start action (Andrew Chow)
Pull request description:
It was reported on [IRC](http://www.erisian.com.au/bitcoin-core-dev/log-2019-12-11.html#l-377) that `scantxoutset`'s API was broken in 0.19.0:
```
<belcher> i think scantxoutset may have been broken in bitcoin core 0.19 ? regardless of what parameters i run it with (e.g. "scantxoutset abort", "scantxoutset status") it just returns the help doc, according to the release notes the only change was https://github.com/bitcoin/bitcoin/pull/16285/files but i dont see anything that wouldve broken it, it works fine in 0.18
<belcher> im on regtest, in case its important
<harding> I can confirm `scantxoutset abort` returns the help doc on latest master. Waiting for 0.18.1 to start now to attempt to reproduce there.
<harding> It looks like it's expecting a second parameter (even though that doesn't make sense with "abort").
<jonatack> Same for me as well
<harding> Can also confirm that `scantxoutset abort` returns the expected result on 0.18.1.
```
As noted in the conversation, previously, the second argument of `scanobjects` is only required for the `start` action. `Stop` and `abort` actions did not and could work without them.
It appears that this was broken by #16240 which enforced the size of the arguments to match the listed required arguments.
To fix this issue, this PR makes the `scanobjects` argument an optional argument. Then only in the `start` action do we check whether the `scanobjects` argument is there and throw an informative error about that. Also a test is added for this case.

fc0c410d6e19dd8e3abbc9b0fc13c836e6678750 rpc: Improve scantxoutset response and help message (João Barbosa)
Pull request description:
The new response keys `height` and `bestblock` allow the client to know at what point the scan took place.
The help message now has all the response keys (`result` and `txouts` were missing) and it's improved a bit. Note that `searched_items` key is renamed to `txouts`, considering `scantxoutset` is marked experimental.

Pull request description:
This introduces a consistent notation for RPC arguments in `scantxoutset`, `importmulti`, and `deriveaddresses`, either:
* `"range" : int` to just specify the end of the range
* `"range" : [int,int]` to specify both the begin and the end of the range.
For `scantxoutset`, this is a backward compatible new feature. For the two other RPCs, it's an incompatible change, but neither of them has been in a release so far. Because of that non-released reason, this only makes sense in 0.18, in my opinion.
I suggest this as an alternative to #15496, which only makes `deriveaddresses` compatible with `importmulti`, but not with the existing `scantxoutset` RPC. I also think `[int,int]` is more convenient than `{"start":int,"stop":int}`.
I realize this is technically a feature added to `scantxoutset` after the feature freeze. If desired, I'll drop the `scantxoutset` changes.

Pull request description:
Currently the test_runner would exit if the wallet was not compiled into the Bitcoin Core executable. However, a lot of the tests run without the wallet just fine and there is no need to globally require the wallet to run the tests.
