7d263571be 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.

2081442c42 test: Add test for rpc_whitelist (Emil Engler)
7414d3820c Add RPC Whitelist Feature from #12248 (Jeremy Rubin)
Pull request description:
Summary
====
This patch adds the RPC whitelisting feature requested in #12248. RPC Whitelists help enforce application policies for services being built on top of Bitcoin Core (e.g., your Lightning Node maybe shouldn't be adding new peers). The aim of this PR is not to make it advisable to connect your Bitcoin node to arbitrary services, but to reduce risk and prevent unintended access.
Using RPC Whitelists
====
The way it works is you specify (in your bitcoin.conf) configurations such as
```
rpcauth=user1:4cc74397d6e9972e5ee7671fd241$11849357f26a5be7809c68a032bc2b16ab5dcf6348ef3ed1cf30dae47b8bcc71
rpcauth=user2:181b4a25317bff60f3749adee7d6bca0$d9c331474f1322975fa170a2ffbcb176ba11644211746b27c1d317f265dd4ada
rpcauth=user3:a6c8a511b53b1edcf69c36984985e$13cfba0e626db19061c9d61fa58e712d0319c11db97ad845fa84517f454f6675
rpcwhitelist=user1:getnetworkinfo
rpcwhitelist=user2:getnetworkinfo,getwalletinfo, getbestblockhash
rpcwhitelistdefault=0
```
Now user1 can only call getnetworkinfo, user2 can only call getnetworkinfo or getwalletinfo, while user3 can still call all RPCs.
If any rpcwhitelist is set, act as if all users are subject to whitelists unless rpcwhitelistdefault is set to 0. If rpcwhitelistdefault is set to 1 and no rpcwhitelist is set, act as if all users are subject to whitelists.
Review Request
=====
In addition to normal review, would love specific review from someone working on LN (e.g., @ roasbeef) and someone working on an infrastructure team at an exchange (e.g., @ jimpo) to check that this works well with their system.
Notes
=====
The rpc list is spelling sensitive -- whitespace is stripped though. Spelling errors fail towards the RPC call being blocked, which is safer.
It was unclear to me if HTTPReq_JSONRPC is the best function to patch this functionality into, or if it would be better to place it in exec or somewhere else.
It was also unclear to me if it would be preferred to cache the whitelists on startup or parse them on every RPC as is done with multiUserAuthorized. I opted for the cached approach as I thought it was a bit cleaner.
Future Work
=====
In a future PR, I would like to add an inheritance scheme. This seemed more controversial so I didn't want to include that here. Inheritance semantics are tricky, but it would also make these whitelists easier to read.
It also might be good to add a `getrpcwhitelist` command to facilitate permission discovery.
Tests
=====
Thanks to @ emilengler for adding tests for this feature. The tests cover all cases except for where `rpcwhitelistdefault=1` is used, given difficulties around testing with the current test framework.

4341bffb6e GUI: Refactor formatServicesStr to warn when a ServicesFlag is missing (Luke Dashjr)
df77de8c21 Bugfix: GUI: Recognise NETWORK_LIMITED in formatServicesStr (Luke Dashjr)
Pull request description:
Currently, only the bottom 8 service bits are shown in the GUI peer details view.
`NODE_NETWORK_LIMITED` is the 11th bit (2^10).
The first commit expands the range to cover the full 64 bits, and properly label `"NETWORK_LIMITED"`.
The second commit refactors the code so that any future omitted service bits will trigger a compile warning.

There was an issue around the time of Qt 4.6 when placeholder text was
introduced, that caused a compile failure when it was specified in the
form.
As a workaround the placeholder texts were moved to the code.
Qt 4 hasn't been relevant to us for ages. So move all (non-parametrized)
placeholder texts to the form files instead.
It's better to keep this kind of text content together. Makes sure
translate/no-translate status is kept as it is.
Removes SetCrypted() and fUseCrypto as we don't need them anymore.
SetCrypted calls in LegacyScriptPubKeyMan are replaced with mapKeys.empty()
IsCrypted() is changed to just call HasEncryptionKeys()

Pull request description:
* The `pwallet->CanGetAddresses()` call in `ReserveDestination::GetReservedDestination` to `LegacyScriptPubKeyMan::GetReservedDestination` so that the sanity check results in a failure when a `ScriptPubKeyMan` individually cannot get a destination, not when any of the `ScriptPubKeyMan`s can't.
* `ScriptPubKeyMan::GetReservedDestination` is changed to return the destination so that future `ScriptPubKeyMan`s can return destinations constructed in other ways. This is implemented for `LegacyScriptPubKeyMan` by moving key-to-destination code from `CWallet` to `LegacyScriptPubKeyMan`
* In order for `ScriptPubKeyMan` to be generic and work with future `ScriptPubKeyMan`s, `ScriptPubKeyMan::ReturnDestination` is changed to take a `CTxDestination` instead of a `CPubKey`. Since `LegacyScriptPubKeyMan` still deals with keys internally, a new map `m_reserved_key_to_index` is added in order to track the keypool indexes that have been reserved.
* A bug is fixed in how the total keypool size is calculated as it was omitting `set_pre_split_keypool` which is a bug.
