Pull request description:
Make DNS lookup mockable/testable/fuzzable.
Add fuzzing harness for `Lookup(…)`/`LookupHost(…)`/`LookupNumeric(…)`/`LookupSubNet(…)`.
See [`doc/fuzzing.md`](https://github.com/bitcoin/bitcoin/blob/master/doc/fuzzing.md) for information on how to fuzz Bitcoin Core. Don't forget to contribute any coverage increasing inputs you find to the [Bitcoin Core fuzzing corpus repo](https://github.com/bitcoin-core/qa-assets).
Happy fuzzing :)

14f3d9b908 refactor: Add RPC server ExecuteCommands function (Russell Yanofsky)
6158a6d397 refactor: Replace JSONRPCRequest fHelp field with mode field (Russell Yanofsky)
Pull request description:
This change is needed to fix the `rpc_help.py` test failing in #10102: https://cirrus-ci.com/task/5469433013469184?command=ci#L2275
The [`CRPCTable::dumpArgMap`](16b784d953/src/rpc/server.cpp (L492)) method currently works by casting RPC `unique_id` integer field to a function pointer, and then calling it. The `unique_id` field wasn't supposed to be used this way (it's meant to be used to detect RPC aliases) and as a result, this code segfaults in the `rpc_help.py` test in multiprocess PR #10102 because wallet RPC functions aren't directly accessible from the node process.
Fix this by adding a new `GET_ARGS` RPC request mode to retrieve argument information similar to the way the `GET_HELP` mode retrieves help information.

737feadff7 contrib/init: (OpenRC) Do not fail if both rpcuser and rpcpassword are unset. (parazyd)
Pull request description:
This pull request improves the available OpenRC initscripts in
`contrib/init`.
The first commit (737feadff7) reworks
`checkconfig()` to not fail if **both** `rpcuser` and `rpcpassword`
are unset, because this implies that bitcoind shall use the `.cookie`
file for RPC authentication. Currently, the initscript does not allow
starting bitcoind without a set `rpcuser` and `rpcpassword`.
The second commit (95f97111dd) simply
quotes some unquoted variables.

1a6323bdbe doc: update developer notes for removal of MakeUnique (fanquake)
3ba2840e7e scripted-diff: remove MakeUnique<T>() (fanquake)
Pull request description:
Since requiring C++17, this is just pointless abstraction. I think we should just "tear the band-aid off" and remove it. Similar to the changes happening in #21366.
Also, having a comment saying this is deprecated doesn't prevent it's usage in new code. i.e : https://github.com/bitcoin/bitcoin/pull/20946#discussion_r561949731.
The repository is fairly quiet at the moment, so any potential complaints about having to rebase should be minimal. Might as well get this over and done with.

e017a913d0 bitcoind: Add -daemonwait option to wait for initialization (Wladimir J. van der Laan)
c3e6fdee6d shutdown: Use RAII TokenPipe in shutdown (Wladimir J. van der Laan)
612f746a8f util: Add RAII TokenPipe (Wladimir J. van der Laan)
Pull request description:
This adds a `-daemonwait` flag that does the same as `-daemon` except that it, from a user perspective, backgrounds the process only after initialization is complete. This is similar to the behaviour of some other software such as c-lightning.
This can be useful when the process launching bitcoind wants to guarantee that either the RPC server is running, or that initialization failed, before continuing. The exit code indicates the initialization result.
The use of the libc function `daemon()` is replaced by a custom implementation which is inspired by the [glibc implementation](https://github.com/lattera/glibc/blob/master/misc/daemon.c#L44), but which also creates a pipe from the child to the parent process for communication.
An additional advantage of having our own `daemon()` implementation is that no MACOS-specific pragmas are needed anymore to silence a deprecation warning.
TODO:
- [x] Factor out `token_read` and `token_write` to an utility, and use them in `shutdown.cpp` as well—this is exactly the same kind of communication mechanism.
- [x] RAII-ify pipe endpoints.
- [x] Improve granularity of the `configure.ac` checks. This currently still checks for the function `daemon()` which makes no sense as it's not used. It should check for individual functions such as
`fork()` and `setsid()` etc—the former being required, the second optional.
- [-] ~~Signal propagation during initialization: if say, pressing Ctrl-C during `-daemonwait` it would be good to pass this SIGINT on to the child process instead of detaching the parent process and letting the child run free.~~ This is not necessary, see https://github.com/bitcoin/bitcoin/pull/21007#issuecomment-769007341.
Future:
- Consider if it makes sense to use this in the RPC tests (there would be no more need for "is RPC ready" polling loops). I think this is out of scope for this PR.

Switch to Qt 5.12.10 in depends. Based on #21363. This is a much smaller changeset, and should be easier to review than #19716. Also postpones needing to bring a bunch of new libs into depends.

Overall PR: #20158 (tree-wide: De-globalize ChainstateManager)
Based on:
- [x] #21055 | [Bundle 3/n] Prune g_chainman usage in mempool-related validation functions
Note to reviewers:
1. This bundle may _apparently_ introduce usage of `g_chainman` or `::Chain(state|)Active()` globals, but these are resolved later on in the overall PR. [Commits of overall PR](https://github.com/bitcoin/bitcoin/pull/20158/commits)
2. There may be seemingly obvious local references to `ChainstateManager` or other validation objects which are not being used in callers of the current function in question, this is done intentionally to **_keep each commit centered around one function/method_** to ease review and to make the overall change systematic. We don't assume anything about our callers. Rest assured that once we are considering that particular caller in later commits, we will use the obvious local references. [Commits of overall PR](https://github.com/bitcoin/bitcoin/pull/20158/commits)
3. When changing a function/method that has many callers (e.g. `LookupBlockIndex` with 55 callers), it is sometimes easier (and less error-prone) to use a scripted-diff. When doing so, there will be 3 commits in sequence so that every commit compiles like so:
1. Add `new_function`, make `old_function` a wrapper of `new_function`, divert all calls to `old_function` to `new_function` **in the local module only**
2. Scripted-diff to divert all calls to `old_function` to `new_function` **in the rest of the codebase**
3. Remove `old_function`
