Pull request description:
## Motivation
This pull request achieves the goal originally set out in [dash#5167](https://github.com/dashpay/dash/pull/5167), to migrate the base of our Statsd client implementation to one that is actively maintained. Statoshi ([source](54c3ffdcf0/src/statsd_client.cpp)) utilizes [talebook/statsd-client-cpp](https://github.com/talebook/statsd-client-cpp), which in turn is inherited by Dash.
As Statsd is the only cross-platform reporting mechanism available (USDT requires a Linux host with superuser privileges and RPCs don't provide as much flexibility as desired), emphasis is placed on using Statsd as the primary way for the Dash daemon to report metrics related to node and network health.
As part of maintaining our Statsd client, this PR aims to migrate the base of our implementation to [vthiery/cpp-statsd-client](https://github.com/vthiery/cpp-statsd-client), a streamlined implementation that embraces C++11 with a thread-safe implementation of queueing and batching, which reduces the number of packets used to transmit stats.
These capabilities are optional and users can opt not to use them by setting `-statsduration=0` to disable queueing (which will also disable batching) or `-statsbatchsize=0`, which will disable batching (but will not disable queueing unless requested explicitly).
## Additional Information
* Dependent on https://github.com/dashpay/dash/pull/5167
* `RawSender` (and by extension, `RawMessage`) strive to remain as unopinionated as possible, moving the responsibility to construct valid Statsd messages onto `StatsdClient`. This is to ensure that `RawSender` can be reused down the line or independently extended without impacting the Statsd client.
* `RawMessage` exists to provide extensions to `std::vector<uint8_t>` that make it easier to abstract away strings while also implementing some of its semantics like `append()` (and its alias, `+=`).
* `InitStatsClient()` was introduced to keep `StatsdClient` indifferent to _how_ arguments are obtained and sanitized before they're supplied to the constructor. This is to keep it indifferent to all the backwards-compatibility code for deprecated arguments still work.
* When constructing the Statsd message, we can use `%f` without having to specify a precision as tinyformat automatically assumes a precision of 6 ([source](17110f50b3/src/tinyformat.h (L673))) and problems don't seem to be observed when using `%f` with integers ([source](https://github.com/dashpay/dash/pull/6267#issuecomment-2345592051)).
* As a guardrail, there is a `static_assert` to ensure that a specialization of `send()` involving a non-arithmetic type will raise alarm when compiling ([source](a0ce720207/src/stats/client.cpp (L145))).
## Breaking changes
* `-statsenabled` (replaced with specifying `-statshost`), `-statshostname` (replaced by `-statssuffix`) and `-statsns` (replaced by `-statsprefix`) have been deprecated and will be removed in a future release.

`RawSender` is inspired by `UDPSender` from `vthiery/cpp-statsd-client`
and separating it out of `StatsdClient` is needed to implement queueing
and batching support in upcoming commits.
This is the start of migrating our Statsd codebase to `cpp-statsd-client`.
In upcoming commits, message sending will be split off into a separate
file and stats capabilities will be fleshed out. Prepare for that by
giving it its own directory.
Also get rid of `statsd` namespace, it is entirely unnecessary.

Pull request description:
## Additional Information
* In [bitcoin#22831](https://github.com/bitcoin/bitcoin/pull/22831), when restarting the node in `rpc_net.py`'s `test_addpeeraddress()`, existing commands need to be appended to `extra_args` to ensure they're retained when the node is restarted (default behavior is to overwrite the argument list with `extra_args`) to prevent the test from hanging and then failing due to missing fast DIP3 activation params from the arguments list.
Missing arguments result in a block database sanity check failure on restart due to `bad-qc-premature` arising from the activation height being higher than the height of a block with a quorum commitment.
* `NodeContext` was moved from `TestingSetup` to `BasicTestingSetup` in [bitcoin#18571](https://github.com/bitcoin/bitcoin/pull/18571) ([dash#4844](https://github.com/dashpay/dash/pull/4844)) but `connman` as a `BasicTestingSetup` variable still stuck around (despite `NodeContext`'s presence making this unnecessary).
To prepare for [bitcoin#22910](https://github.com/bitcoin/bitcoin/pull/22910), the remnant variable has been replaced with `m_node.connman` and adjustments have been made to that effect.

Pull request description:
Error was reported by SatoriHoshiAiko in https://github.com/bitcoin/bitcoin/issues/25207 and happens unpredictably because make doesn't always build dependencies in the same order.
The source file `src/ipc/capnp/protocol.cpp` includes some generated headers so needs to have an explicit dependency specified in the makefile so the headers will be generated before the file is compiled. #19160 added the explicit dependency, but it was incorrect because it referred to an old file path from before the source file was renamed (`ipc.cpp` -> `protocol.cpp`)

This PR adds basic process spawning and IPC method call support to `bitcoin-node` executables built with `--enable-multiprocess`[*].
These changes are used in https://github.com/bitcoin/bitcoin/pull/10102 to let node, gui, and wallet functionality run in different processes, and extended in https://github.com/bitcoin/bitcoin/pull/19460 and https://github.com/bitcoin/bitcoin/pull/19461 after that to allow gui and wallet processes to be started and stopped independently and connect to the node over a socket.
These changes can also be used to implement new functionality outside the `bitcoin-node` process like external indexes or pluggable transports (https://github.com/bitcoin/bitcoin/pull/18988). The `Ipc::spawnProcess` and `Ipc::serveProcess` methods added here are entry points for spawning a child process and serving a parent process, and being able to make bidirectional, multithreaded method calls between the processes. A simple example of this is implemented in commit "Add echoipc RPC method and test."
Changes in this PR aside from the echo test were originally part of #10102, but have been split and moved here for easier review, and so they can be used for other applications like external plugins.
Additional notes about this PR can be found at https://bitcoincore.reviews/19160
[*] Note: the `--enable-multiprocess` feature is still experimental, and not enabled by default, and not yet supported on windows. More information can be found in [doc/multiprocess.md](https://github.com/bitcoin/bitcoin/blob/master/doc/multiprocess.md)

I [wrote a little script](https://github.com/martinus/bitcoin-stuff/blob/main/scripts/parse-debuglog-contention-single.rb) to parse the `debug.log` and summarize the output to see if anything interesting was going on, here is the result:

612f746a8ffa265b6877bedbbe21fcbb392f1516 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.

e1e7a90d5f0616a46ffadd62a9f1c65406cca6b4 wallettool: Add dump command (Andrew Chow)
Pull request description:
Adds two commands to the `bitcoin-wallet` tool: `dump` and `createfromdump`. These commands will be useful for a wallet storage migration in the future. It is also generally useful to have a storage agnostic dump like this. These commands are similar to BDB's `db_dump` and `db_load` tools. This can also be useful for manual construction of a wallet file for tests.
`dump` outputs every key-value pair from the wallet as comma separated hex. Each key-value pair is on its own line with the key and value in hex separated by a comma. This is output to the file specified by the new `-dumpfile` option.
`createfromdump` takes a file produced by `dump` and creates a new wallet file with exactly the records specified in that file.
A new option `-dumpfile` is added to the wallet tool. When used with `dump`, the records will be written to the specified file. When used with `createfromdump`, the file is read and the key-value pairs constructed from it. `createfromdump` requires `-dumpfile`.
A simple round-trip test is added to the `tool_wallet.py`.
