GetWarnings() changes the format of the output warning string based on a
passed-in string argument that can be set to "gui" or "statusbar".
Change the argument to a bool:
- there are only two types of behaviour, so a bool is a more natural
argument type
- changing the name to 'verbose' does not set any expectations for the
how the calling code will use the returned string (currently,
'statusbar' is used for RPC warnings, not a status bar)
- removes some error-handling code for when the passed-in string is not
one of the two strings expected.
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.

This performs the same function as -Wl,-z,now, except for ld on macOS.
You can check the binaries using otool -l, looking for the
LC_DYLD_INFO_ONLY section. lazy_bind_off and lazy_bind_size should both
be 0.
man ld:
-bind_at_load
Sets a bit in the mach header of the resulting binary which tells dyld
to bind all symbols when the binary is loaded, rather than lazily.
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.

75d9317bc1 Update msvc build for Visual Studio 2019 v16.4 (Aaron Clauson)
Pull request description:
msvc warning C4834 for the Bitcoin Core build was introduced by Visual Studio 16.4.0. This PR adds an ignore rule for the warning (it's related to the nodiscard attribute and is not considered relevant).
An additional side effect of the msvc compiler update is the prebuilt Qt5.9.8 libraries cannot be linked due to being built with an earlier version of the compiler. To fix this a new Qt5.9.8 version has been compiled and the appveyor job updated to use them.
The GitHub Actions job needs to continue to use the original Qt5.9.8 libraries until the latest GitHub Windows image also updates to >= Visual Studio 2019 v16.4.

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.

b0b1531737 Adds GitHub Action workflow which duplicates AppVeyor job. (Aaron Clauson)
Pull request description:
As discussed in #17594 this PR contains a GitHub Action workflow file that performs the same job as the current Appveyor CI task except for the Python functional tests. For the latter I've been unable to get them to execute successfully due to a Unicode error. I've tried on and off for a week to get it to work but with no joy.
It may be that someone more proficient in Python will recognise the error and be able to provide a pointer on how to proceed. I've tried some obvious things like changing the Windows console code page.
To run this job it should just be a matter of clicking on the GitHub `Actions` tab and enabling workflows. It's also not required that the file is on the `master` branch for the job to run. If anyone else wants to run the job they can pull this PR into their own fork and enable `Actions` (it's free).

5db506ba59 tests: Add option --valgrind to run nodes under valgrind in the functional tests (practicalswift)
Pull request description:
What is better than fixing bugs? Fixing entire bug classes of course! :)
Add option `--valgrind` to run the functional tests under Valgrind.
Regular functional testing under Valgrind would have caught many of the uninitialized reads we've seen historically.
Let's kill this bug class once and for all: let's never use an uninitialized value ever again. Or at least not one that would be triggered by running the functional tests! :)
My hope is that this addition will make it super-easy to run the functional tests under Valgrind and thus increase the probability of people making use of it :)
Hopefully `test/functional/test_runner.py --valgrind` will become a natural part of the pre-release QA process.
**Usage:**
```
$ test/functional/test_runner.py --help
…
--valgrind run nodes under the valgrind memory error detector:
expect at least a ~10x slowdown, valgrind 3.14 or
later required
```
**Live demo:**
First, let's re-introduce a memory bug by reverting the recent P2P uninitialized read bug fix from PR #17624 ("net: Fix an uninitialized read in ProcessMessage(…, "tx", …) when receiving a transaction we already have").
```
$ git diff

Second, let's test as normal without Valgrind:
```
