c767974811 clang-tidy: Fix critical warnings
The std::move in coinstatsindex was not necessary since it was passed as a const reference argument.

The other change in the utxo supply fuzz test changes a line that seems to have triggered a false alarm.

54dc34ec22 index: Remove unused coinstatsindex recovery code
The coinstatsindex currently looks for block data at a hash key if the prev block in CustomAppend is different than expected. This is not needed since base index should always prevent us ending up in this scenario since it should rewind the index before calling CustomAppend in this case. But even if we run into this and our belt-and-suspenders code is getting hit, the index could not recover properly from the hash key index data so it can be removed without any real impact.

37c4fba1f4 index: Check BIP30 blocks when rewinding Coinstatsindex
This is practically irrelevant due to the unlikeliness of a re-org
reaching so deep that it would drop the BIP30 blocks from the chain
(91842 and 91880). However this serves as documentation and ensures that
the functions RevertBlock and CustomAppend are consistent.

431a076ae6 index: Fix coinstatsindex overflow issue
The index originally stored cumulative values in a CAmount type but this allowed for
potential overflow issues which were observed on Signet. Fix this by
storing the values that are in danger of overflowing in a arith_uint256.

Also turns an unnecessary copy into a reference in RevertBlock and
CustomAppend and gets
rid of the explicit total unspendable tracking which can be calculated
by adding the four categories of unspendables together.

3cc9a06c8d test: Add TestNode ipcbind option
With this change, tests can specify `self.extra_init = [{ipcbind: True}]` to
start a node listening on an IPC socket, instead of needing to choose which
node binary to invoke and what `self.extra_args=[["-ipcbind=..."]]` value to
pass to it.

The eliminates boilerplate code #30437 (interface_ipc_mining.py), #32297
(interface_ipc_cli.py), and #33201 (interface_ipc.py) previously needed in
their test setup.

3cceb60a71 test: Provide path to bitcoin binary
Set new `BitcoinTestFramework.binary_paths.bitcoin_bin` property with path to
the `bitcoin` wrapper binary. This allows new tests for `bitcoin-mine` in
#30437 and `bitcoin-cli` in #32297 to find the `bitcoin` binary and call
`bitcoin -m` to start nodes with IPC support. This way the new tests can run
whenever the ENABLE_IPC build option is enabled, instead of only running when
the `BITCOIN_CMD` environment variable is set to `bitcoin -m`

4f1a4cbccd net: Quiet down logging when router doesn't support natpmp/pcp (laanwj)

Pull request description:

  When the router doesn't support natpmp and PCP, one'd normally expect the UDP packet to be ignored, and hit a time out. This logs a message that is already in the debug category. However, there's also the case in which sending an UDP packet causes a ICMP response (type 3, code 3 "port unreachable"). This is returned to user space as "connection refused" (despite UDP having no concept of connections).

  Move the warnings from `Send` and `Recv` to debug level too, to reduce log spam in that case.

  Closes #33301.

Pull request description:

  ...for default route in pcp pinholing.

  Currently we only make a single recv call, which trucates results from large routing tables, or in the case the kernel may split the message into multiple responses (which may happen with `NLM_F_DUMP`).

  We also do not filter on the default route. For IPv6, this led to selecting the first route with an `RTA_GATEWAY` attribute, often a non-default route instead of the actual default. This caused PCP port mapping failures because the wrong gateway was used.

  Fix both issues by adding multi-part handling of responses and filter for the default route.

  Limit responses to ~ 1MB to prevent any router-based DoS.

88db09bafe net: handle multi-part netlink responses
Handle multi-part netlink responses to prevent truncated results from
large routing tables.

Previously, we only made a single recv call, which led to incomplete
results when the kernel split the message into multiple responses (which
happens frequently with NLM_F_DUMP).

Also guard against a potential hanging issue where the code would
indefinitely wait for NLMSG_DONE for non-multi-part responses by
detecting the NLM_F_MULTI flag and only continue waiting when necessary.

Pull request description:

  This changeset migrates all current self-hosted CI jobs over to hosted [Cirrus Runners](https://cirrus-runners.app/).

  These runners cost a flat rate of $150/month, and we qualify for an open source discount of 50%. Therefore they are $75/month/runner.

  One "runner" should more accurately be thought of in terms of the number of vCPU you are purchasing: https://cirrus-runners.app/pricing/ or in terms of "concurrency", where 1 runners gets you 1.0 concurrency.
  e.g. a Linux x86 Runner gets you 16 vCPU (1.0 concurrency) and 64GB RAM to be provisioned as you choose, amongst one or more jobs.

  Cirrus Runners currently only support Linux (x86 and Arm64) and MacOS (Arm64).
  This changeset does **not** move the existing Github Actions native MacOS runners away from being run on Github's infrastructure. This could be a follow up optimisation.

  Runs from this changeset using Cirrus Runners can be found at: https://github.com/testing-cirrus-runners/bitcoin2/actions which shows an uncached run on master ([CI#1](https://github.com/testing-cirrus-runners/bitcoin2/actions/runs/16298637161)), an outside pull request ([CI#3](https://github.com/testing-cirrus-runners/bitcoin2/actions/runs/16303305483?pr=1)) and an updated push to master ([CI#4](https://github.com/testing-cirrus-runners/bitcoin2/actions/runs/16304182527)).

  These workflows were run on 10 runners, and we would recommend purchasing a similar number for our CI in this repo to achieve the speed and concurrency we expect.

  We include some optional performance commits, but these could be split out and made into followups or dropped entirely.

  ## Benefits

  ### Maintenance

  As we are not self-hosting, nobody needs to maintain servers, disks etc.

  ### Bus factor

  Currently we have a very small number of people with the know-how working on server setup and maintenance. This setup fixes that so that "anyone" familiar with GitHub-style CI systems can work on it.

  ### Scaling

  These do _not_ "auto-scale"/have "unlimited concurrency" like some solutions, but if we want more workers/cpu to increase parallism or increase the runner size of certain jobs for a speed-up we can simply buy more concurrency using the web interface.

  ### Speed

  Runtimes aproximate current runtimes pretty well, with some jobs being faster.
  Caching improvements on pull request (re-runs) are left as future optimisations from the current changeset (see below).

  ### GitHub workflow syntax

  With a migration to the more-commonly-used GitHub workflow syntax, migration to other providers in the future is often as simple as a one-line change (and installing a new GitHub app to the repo).

  If we decide to self-host again, then we can also self-host GitHub runners (using https://github.com/actions/runner) and maintain new GH-style CI syntax.

  ### Reporting

  GitHub workflows provide nicer built-in reporting directly on the "Checks" page of a pr. This includes more-detailed action reporting, and a host of pretty nice integrated features, such as [Workflow Commands](https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/workflow-commands-for-github-actions) for creating annotations that can print messages during runs. See for example at the bottom of this window where we report `ccache` hitrate, if it was below 90%: https://github.com/testing-cirrus-runners/bitcoin/actions/runs/16163449125?pr=1

  These could be added conditionally into our CI scripts to report interesting or other information.

  ## Costs

  ### Financial

  Relative to competitors Cirrus runners are cheap for the hosted CI-world. However these are likely more expensive than our current setup, or a well-configured (new) self-hosted setup.

  If we started with 10 runners to be shared amongst all migrated jobs, this would total $750/mo = $9000/yr.

  Note that we are not trying to comptete here on cost directly.

  ### Dependencies

  We would be dependent on Cirrus infra.

  ## Forks

  - Forks should be able to run CI without paid Cirrus runners. This behaviour is achieved through a rather verbose `runs-on:` directive.
    - This directive hardcodes the main repo (unfortunately you cannot use the `env` github context in this field in particular, for some reason).
    - This directive also allows for a fork to patch the `runs-on:` field in the ci.yml file if they want to use Cirrus Runners too.
    - The workflow otherwise will fallback to the GitHub free runners on forks.
  - This cirrus cache action transparently falls back to github actions cache when not running on cirrus, so forks will get some free github caching (10GB per repo).

  All jobs work on forks, but will run (slowly) on GitHub native free hosted runners, instead of Cirrus runners. They will also suffer from poor cache hit-rates, but there's nothing that can be done about that, and the situtation is an improvement on today.

  ## Migration process

  The main org should also, in addition to pulling code changes:

  1. Permit the actions `docker/setup-buildx-action@v3` and `docker/login-action@v3` to be run in this repo.

  ## Caching

  For the number of CI jobs we have, cache usage on GitHub would be an issue as GH only provides 10GB of cache space, **per repo**. However cirrus provides [10 GB per runner](https://cirrus-runners.app/setup/#speeding-up-the-cache), which scales better with the number of runners.

  The `cirruslabs/action/[restore|save]` action we use here redirects this to Cirrus' own cache and is both faster and larger.

  In the case that user is running CI on a fork, the cirrus cache falls back transparently to GitHub default cache without error.

  ### ccache, depends-sources, built-depends

  - Cached as blobs via `cirruslabs/actions/cache` action.
  - Current implementation:
    - On `push`: restores and saves caches.
    - On `pull_request`: restores but does **not** save caches.

  This means a new pull request should hit a _pretty relevant_ cache.
  Old pull requests **which are not being rebased on master** may suffer from lower cache hit-rate.

  If we save caches on all pull request runs we run the risk of evicting recent (and more relevant) cache blobs.
  It may be possible in a future optimisation to widen this to save on pull request runs too, but it will also depend on how many runners we provision and what cache churn rates are like in the main repo.

  ### Docker build layer caching

  - Cached using the `gha` cache backend
  - These cache blobs compete for space with `ccache`, `depends-sources` and `depends-built` caches
  - `gha` cache allows `--cache-from` to be used from pull requests, which does not work using a registry cache type (technically we could use a public read-only token to get this working, but that feels wrong)

  This backend does network i/o and so are marginally slower than our current disk i/o cache.

  ## But what about... `x`?

  We have tested many other providers, including [Runs-on](https://runs-on.com/), [Buildjet](https://buildjet.com/), [WarpBuild](https://www.warpbuild.com/), and GitHub hosted runners (and investigated even more). But they all fall short in one-way or another.

  - Runs-On and Buildjet (and others) require installing GH apps with much too-liberal permissions (e.g. `Administration: Read|Write`) for our use-case.
  - GitHub hosted runners suffer from all of high costs, lower speed, small cache, and the requirement for a GitHub Teams subscription.
  - WarpBuild seems to be simply too expensive.

  ## TODO:

  To complete migration from self-hosted to hosted for this repo, the backport branches `27.x`, `28.x` and `29.x` would also need their CI ported, but these are left for followups to this change (and pending review/changes here first).

2885bd0e1c doc: unify `datacarriersize` warning with release notes (Lőrinc)

Pull request description:

  Follow-up to https://github.com/bitcoin/bitcoin/pull/32406

  ---

  The [release notes](a189d63618/doc/release-notes-32406.md (L1)) claim

  > [...] marked as deprecated and are expected to be removed in a future release

  but the [warning itself](2885bd0e1c/src/init.cpp (L907)) claims

  > [...] marked as deprecated. They **will** be removed in a future version.

  To be less aggressive (since some have objected against this version online) - and to unify the deprecation warning with the release notes - I have changed the warning to communicate our expectation in a friendlier way.

    Code review ACK 2885bd0e1c. I don't think it is good for the release notes and the runtime warning message to say two different things. I'd also be happy if release notes were updated to match the runtime warning, instead of vice versa. Whatever is more accurate is better.
