fa6e6a3f03 doc: Remove confusing assert linter (MarcoFalke)
Pull request description:
The `assert()` documentation and linter are redundant and confusing:
* The source code already refuses to compile with `assert()` disabled.
* They violate the assumptions about `Assert()`, which *requires* side effects.
* The existing linter doesn't enforce the guideline, only checking for `++` and `--` side effects.
Fix all issues by removing the docs and the linter. See also https://github.com/bitcoin/bitcoin/pull/26684#discussion_r1287370102
Going forward everyone is free to use whatever code in this regard they think is the easiest to read. Also, everyone is still free to share style-nits, if they think it is a good use of their time and of the pull request author. Finally, the author is still free to dismiss or ignore this style-nit, or any other style-nit.

This changeset finishes the first phase of the assumeutxo project. It makes UTXO snapshots loadable via RPC (`loadtxoutset`) and adds `assumeutxo` parameters to chainparams. It contains all the remaining changes necessary to both use an assumedvalid snapshot chainstate and do a full validation sync in the background.
This may look like a lot to review, but note that
- ~200 lines are a (non-essential) demo shell script
- Many lines are functional test, documentation, and relatively dilute RPC code.
So it shouldn't be as burdensome to review as the linecount might suggest.
- **P2P**: minor changes are made to `init.cpp` and `net_processing.cpp` to make simultaneous IBD across multiple chainstates work.
- **Pruning**: implement correct pruning behavior when using a background chainstate
- **Blockfile separation**: to prevent "fragmentation" in blockfile storage, have background chainstates use separate blockfiles from active snapshot chainstates to avoid interleaving heights and impairing pruning.
- **Indexing**: some `CValidationInterface` events are given with an additional parameter, ChainstateRole, and all indexers ignore events from ChainstateRole::ASSUMEDVALID so that indexation only happens sequentially.
- Have `-reindex` properly wipe snapshot chainstates.
- **RPC**: introduce RPC commands `loadtxoutset` and (hidden) `getchainstates`.
- **Release docs & first assumeutxo commitment**: add notes and a particular assumeutxo hash value for first AU-enabled release.
- This will complete the project and allow use of UTXO snapshots for faster node bootstrap.
The next phase, if it were to be pursued, would be coming up with a way to distribute the UTXO snapshots over the P2P network.

### UTXO snapshots
Create your own with `./contrib/devtools/utxo_snapshot.sh`, e.g.
```shell
./contrib/devtools/utxo_snapshot.sh 788000 utxo.dat ./src/bitcoin-cli -datadir=$(pwd)/testdata`)
```
or use the pre-generated ones listed below.

### Testing
#### For fun (~5min)
If you want to do a quick test, you can run `./contrib/devtools/test_utxo_snapshots.sh` and follow the instructions. This is mostly obviated by the functional tests, though.
#### For real (longer)
If you'd like to experience a real usage of assumeutxo, you can do that too.
I've cut a new snapshot at height 788'000 (http://img.jameso.be/utxo-788000.dat - but you can do it yourself with `./contrib/devtools/utxo_snapshot.sh` if you want). Download that, and then create a datadir for testing:
```sh
$ cd ~/src/bitcoin # or whatever
# get the snapshot
$ curl http://img.jameso.be/utxo-788000.dat > utxo-788000.dat
# you'll want to do this if you like copy/pasting
$ export AU_DATADIR=/home/${USER}/au-test # or wherever
$ mkdir ${AU_DATADIR}
$ vim ${AU_DATADIR}/bitcoin.conf
dbcache=8000 # or, you know, something high
blockfilterindex=1
coinstatsindex=1
prune=3000
logthreadnames=1
```
Obtain this branch, build it, and then start bitcoind:
```sh
$ git remote add jamesob https://github.com/jamesob/bitcoin
$ git fetch jamesob assumeutxo
$ git checkout jamesob/assumeutxo
$ ./configure $conf_args && make # (whatever you like to do here)
# start 'er up and watch the logs
$ ./src/bitcoind -datadir=${AU_DATADIR}
```
Then, in some other window, load the snapshot
```sh
$ ./src/bitcoin-cli -datadir=${AU_DATADIR} loadtxoutset $(pwd)/utxo-788000.dat
```
You'll see some log messages about headers retrieval and waiting to see the snapshot in the headers chain. Once you get the full headers chain, you'll spend a decent amount of time (~10min) loading the snapshot, checking it, and flushing it to disk. After all that happens, you should be syncing to tip in pretty short order, and you'll see the occasional `[background validation]` log message go by.
In yet another window, you can check out chainstate status with
```sh
$ ./src/bitcoin-cli -datadir=${AU_DATADIR} getchainstates
```
as well as usual favorites like `getblockchaininfo`.

Get rid of all `ShutdownRequested` calls in validation code by introducing an interrupt object that applications can use to cancel long-running kernel operations.
Replace all `AbortNode` calls in validation code with new fatal error and flush error notifications so kernel applications can be notified about failures and choose how to handle them.

This pull request is part of the `libbitcoinkernel` project https://github.com/bitcoin/bitcoin/issues/27587https://github.com/orgs/bitcoin/projects/3 and more specifically its "Step 2: Decouple most non-consensus code from libbitcoinkernel".
The pull request mostly allows dropping the kernel dependency on shutdown.cpp. The only dependency left after this is a `StartShutdown` call which will be removed in followup PR https://github.com/bitcoin/bitcoin/pull/27711. This PR also drops the last reference to the `uiInterface` global in kernel code. The process of moving the `uiInterface` out of the kernel was started in https://github.com/bitcoin/bitcoin/pull/27636.
This pull request contains a subset of patches originally proposed in #27711. It will be part of a series of changes required to make handling of interrupts (or in other words the current shutdown procedure) in the kernel library more transparent and less reliable on global mutable state. The set of patches contained here was originally proposed by @ryanofsky [here](https://github.com/bitcoin/bitcoin/pull/27711#issuecomment-1580779869).

FatalError replaces what previously was the AbortNode function in
shutdown.cpp.
This commit is part of the libbitcoinkernel project and further removes
the shutdown's and, more generally, the kernel library's dependency on
interface_ui with a kernel notification method. By removing interface_ui
from the kernel library, its dependency on boost is reduced to just
boost::multi_index. At the same time it also takes a step towards
de-globalising the interrupt infrastructure.

398c3719b0 lint: Fix lint-format-strings false positives when format specifiers have argument positions (Ryan Ofsky)
Pull request description:
Show an error on startup if a bitcoin datadir that is being used contains a `bitcoin.conf` file that is ignored. There are two cases where this could happen:
- One case reported in [#27246 (comment)](https://github.com/bitcoin/bitcoin/issues/27246#issuecomment-1470006043) happens when a `bitcoin.conf` file in the default datadir (e.g. `$HOME/.bitcoin/bitcoin.conf`) has a `datadir=/path` line that sets different datadir containing a second `bitcoin.conf` file. Currently the second `bitcoin.conf` file is ignored with no warning.
- Another way this could happen is if a `-conf=` command line argument points to a configuration file with a `datadir=/path` line and that path contains a `bitcoin.conf` file, which is currently ignored.
This change only adds an error message and doesn't change anything about way settings are applied. It also doesn't trigger errors if there are redundant `-datadir` or `-conf` settings pointing at the same configuration file, only if they are pointing at different files and one file is being ignored.

Pull request description:
Adds a Dockerfile configuration ~~(originally written mostly by fanquake)~~ that allows straightforward running of linters with compatible versions locally. This removes a ton of annoyance when trying to appease CI, because many of the linter versions are quite old and difficult to maintain locally.
I realize that people may not be thrilled to add more ancillary tooling to the repo, but I think this makes a lot of sense given the linter versions listed in this container configuration are dictated by this repo (within the CI configuration), so having these things live in two separate places is a recipe for version mismatches.
Eventually we can likely just use this container on CI directly to avoid any chance of inconsistencies between local dev experience and CI.

fad1c55301 lint: Skip COMMIT_RANGE if no CIRRUS_PR (MarcoFalke)
Pull request description:
It doesn't make sense to run this for non-PRs, because:
* There are known whitespace "violations" in previous commits, so the lint may fail
* Once the changes are merged, it is too late to fix them up (force pushes are illegal)
* It isn't possible to determine which commits to run on if there is no reference branch (target branch of the pull request)
Moreover, the test fails on non-master:
* https://github.com/bitcoin/bitcoin/runs/8664441400

This change adds the ability to initialize a snapshot-based chainstate during init if one is detected on disk. This is of course unused as of now (aside from in unittests) given that we haven't yet enabled actually loading snapshots.
Don't be scared! There are some big move-only commits in here.
Accompanying changes include:
- moving the snapshot coinsdb directory from being called `chainstate_[base blockhash]` to `chainstate_snapshot`, since we only support one snapshot in use at a time. This simplifies some logic, but it necessitates writing that base blockhash out to a file within the coinsdb dir. See [discussion here](https://github.com/bitcoin/bitcoin/pull/24232#discussion_r832762880).
- adding a simple fix in `FlushBlockFile()` that avoids a crash when attemping to flush to disk before `LoadBlockIndexDB()` is called, which happens when calling `MaybeRebalanceCaches()` during multiple chainstate init.
- improving the unittest to allow testing with on-disk chainstates - necessary to test a simulated restart and re-initialization.

and also fix spelling in test/lint/lint-locale-dependence.py not caught by the
spelling linter and fix up a paragraph we are touching here in test/README.md.
This changes the snapshot's leveldb chainstate dir name from
`chainstate_[blockhash]` to `chainstate_snapshot`. This simplifies
later logic that loads snapshot data, and enforces the limitation
of a single snapshot at any given time.
Since we still need to persis the blockhash of the base block, we
write that out to a file (`chainstate_snapshot/base_blockhash`) for
later use during initialization, so that we can reinitialize the
snapshot chainstate.
