3eb94ec81b sync: Use decltype(auto) return type for WITH_LOCK (Carl Dong)
Pull request description:
> Now that we're using C++17, we can use the decltype(auto) return type
> for functions and lambda expressions.
>
> As demonstrated in this commit, this can simplify cases where previously
> the compiler failed to deduce the correct return type.
>
> Just for reference, for the "assign to ref" cases fixed here, there are
> 3 possible solutions:
>
> - Return a pointer and immediately deref as used before this commit
> - Make sure the function/lambda returns declspec(auto) as used after
> this commit
> - Class& i = WITH_LOCK(..., return std::ref(...));
>

fa39cdd072 refactor: Use C++17 std::array deduction for OUTPUT_TYPES (MarcoFalke)
Pull request description:
With the new C++17 array deduction rules, an array encompassing all values in an enum can be specified in the same header file that specifies the enum. This is useful to avoid having to repeatedly enumerate all enum values in the code. E.g. the RPC code, but also the fuzz code.

39b43298d9 test: add test for banning of non-IP addresses (Vasil Dimov)
94d335da7f net: allow CSubNet of non-IP networks (Vasil Dimov)
Pull request description:
Allow creation of valid `CSubNet` objects of non-IP networks and only
match the single address they were created from (like /32 for IPv4 or
/128 for IPv6).
This fixes a deficiency in `CConnman::DisconnectNode(const CNetAddr& addr)`
and in `BanMan` which assume that creating a subnet from any address
using the `CSubNet(CNetAddr)` constructor would later match that address
only. Before this change a non-IP subnet would be invalid and would not
match any address.

Pull request description:
The fuzz tests have several problems:
* The array passed to the fuzz engine to pick `net_permission_flags` is outdated
* The process_message* targets has the service flags as well as connection type hardcoded, limiting potential coverage
* The service flags deserialization from the fuzz engine doesn't allow for easy "exact matches". The fuzz engine has to explore a 64-bit space to hit an "exact match" (only one bit set)

Pull request description:
This PR enables the `-Wunused-member-function` compiler diagnostic, as discussed in #19702.
> **Notice**: The `unused-member-function` diagnostic is only available on clang. Therefore, clang should be used to test this PR.
- [x] Include the `-Wunused-member-function`diagnostic in `./configure.ac`. (ed69213c2b)
- [x] Resolve the reported warnings. (819d03b932)
Currently, enabling this flag no longer reports the following warnings:
> **Note**: output from `make 2>&1 | grep "warning: unused member function" | sort | uniq -c`

1 test/util_tests.cpp:1975:14: warning: unused member function 'operator=' [-Wunused-member-function]

All tests have passed locally (from `make check` & `src/test/test_bitcoin`).

fad140e311 test: Set correct nValue for multi-op-return policy check (MarcoFalke)
Pull request description:
`CTxOut::nValue` is default-initialized to `-1`. The dust-threshold for `OP_RETURN` outputs is `0`. Thus, the policy failure would be `dust` instead of `multi-op-return`. The test only passes because the dust check is currently not run.
Avoid that confusion by setting the value to `0`, to ensure the dust check passes.

Pull request description:
The goal of this PR is to be able to depend on `m_inbound_onion` in AttemptToEvictConnection in #20197:
- asserts `CNode::m_inbound_onion` is inbound in the CNode ctor to have a validity check at the class boundary
- fixes a unit test and a fuzz utility that were passing invalid inbound onion values to the CNode ctor
- drops an unneeded check in `CNode::ConnectedThroughNetwork()` for its inbound status
- adds a public getter `IsInboundOnion()` that also allows unit testing it
- adds unit test coverage
