3fba3d5dee [refactor] Make signals optional in mempool and chainman (TheCharlatan)
Pull request description:
By defining a virtual interface class for the scheduler client, users of the kernel can now define their own event consuming infrastructure, without having to spawn threads or rely on the scheduler design.
Removing `CScheduler` also allows removing the thread and exception modules from the kernel library.
To make the `CMainSignals` class easier to use from a kernel library perspective, remove its global instantiation and adopt RAII practices.
Renames `CMainSignals` to `ValidationSignals`, which more accurately describes its purpose and scope.
Also make the `ValidationSignals` in the `ChainstateManager` and CTxMemPool` optional. This could be useful in the future for using or testing these classes without having to instantiate any form of signal handling.
---
This PR is part of the [libbitcoinkernel project](https://github.com/bitcoin/bitcoin/issues/27587). It improves the kernel API and removes two modules from the kernel library.

This is done in preparation for the next two commits, where the
CMainSignals are de-globalized.
This avoids adding new constructor arguments to the ChainstateManager
and CTxMemPool classes over the next two commits.
This could also allow future tests that are only interested in the
internal behaviour of the classes to forgo instantiating the signals.

Pull request description:
Followup to https://github.com/bitcoin/bitcoin/pull/28459. Add a sanity check that `bti` instructions are present in the arm macho binary, similar to our x86_64 check for control flow.

Pull request description:
This PR resolves#27841 and some more:
- Ensure that the snapshot height is higher than the pruned block height when the node is pruned (Suggested by @Sjors [here](https://github.com/bitcoin/bitcoin/pull/28553#issuecomment-1804941396)).
- Validate the correctness of the file path and check if the file already exists (@hazeycode's [#27845](https://github.com/bitcoin/bitcoin/pull/27845)).
- Make network activity disablement optional for the user (Suggested by @Sjors [here](https://github.com/bitcoin/bitcoin/pull/16899#discussion_r342735815) and [here](https://github.com/bitcoin/bitcoin/pull/16899#issuecomment-536520911)).
- Ensure the `reconsiderblock` command is triggered on exit (@hazeycode's same PR as above), even in the case of user interruption (Ctrl-C).
In order to perform some testing please follow the instructions in the description of previous @hazeycode's PR #27845.

Pull request description:
With Python 3.9 / [PEP 585](https://peps.python.org/pep-0585/), [type hinting has become a little less awkward](https://docs.python.org/3.9/whatsnew/3.9.html#type-hinting-generics-in-standard-collections), as for collection types one doesn't need to import the corresponding capitalized types (`Dict`, `List`, `Set`, `Tuple`, ...) anymore, but can use the built-in types directly (see https://peps.python.org/pep-0585/#implementation for the full list).
This PR applies the replacement for all Python scripts (i.e. in the contrib and test folders) for the basic types, i.e.:
- typing.Dict -> dict
- typing.List -> list
- typing.Set -> set
- typing.Tuple -> tuple
For an additional check, I ran mypy 1.6.1 on both master and the PR branch via
```
$ mypy --ignore-missing-imports --explicit-package-bases $(git ls-files "*.py")
```
and verified that the output is identical -- (from the 22 identified problems, most look like false-positives, it's probably worth it to go deeper here and address them in a follow-up though).

This is deprecated on macOS:
```bash
ld: warning: -bind_at_load is deprecated on macOS
```
and likely redundant anyways, given the behaviour of dyld3.
Unfortunately libtool is still injecting a `-bind_at_load`:
```bash
# Don't allow lazy linking, it breaks C++ global constructors
# But is supposedly fixed on 10.4 or later (yay!).
if test CXX = "$tagname"; then
case ${MACOSX_DEPLOYMENT_TARGET-10.0} in
10.[0123])
func_append compile_command " $wl-bind_at_load"
func_append finalize_command " $wl-bind_at_load"
;;
esac
fi
```
so this doesn't remove all the warnings, but removes us as a potential
source of them.
Note that anywhere the ld64 warnings are being emitted, we are already
not adding this flag to our hardened ldflags, because of `-Wl,-fatal_warnings`.
Since Python 3.9, type hinting has become a little less awkward, as for

348e79f7c6 lint: Include test_utxo_snapshots in lint_shell (Fabian Jahr)
Pull request description:
jamesob excluded `test_utxo_snapshots.sh` from the shell linter with this explanation: "Add the script to the shellcheck exception list since the quoted variables rule needs to be violated in order to get bitcoind to pick up on $EARLY_IBD_FLAGS." However, macrofake pointed out that single lines can be excluded from linting.
This fixes one fixable rule violation, excludes the rest of the offending lines from the linter and then removes the exclusion of the `test_utxo_snapshots.sh` file. Also adds documentation.

3d420d8f28 Add instructions for headerssync-params.py to release-process.md (Pieter Wuille)
53d7d35b58 Update parameters in headerssync.cpp (Pieter Wuille)
7899402cff Add headerssync-params.py script to the repository (Pieter Wuille)
Pull request description:
Builds upon #25946, as it incorporates changes based on the selected values there.
This adds the headerssync tuning parameters optimization script from https://gist.github.com/sipa/016ae445c132cdf65a2791534dfb7ae1 to the repository, updates the parameters based on its output, and adds release process instructions for doing this update in the future.
A few considerations:
* It would be a bit cleaner to have these parameters be part of `CChainParams`, but due to the nature of the approach, it really only applies to chains with unforgeable proof-of-work, which we really can only reasonably expect from mainnet, so I think it's fine to keep them local to `headerssync.cpp`. Keeping them as compile-time evaluatable constants also has a (likely negligible) performance impact (avoiding runtime modulo operations).
* If we want to make sure the chainparams and headerssync params don't go out of date, it could be possible to run the script in CI, and and possibly even have the parameters be generated automatically at build time. I think that's overkill for how unfrequently these need to change, and running the script has non-trivial cost (~minutes in the normal python interpreter).
* A viable alternative is just leaving this out-of-repo entirely, and just do ad-hoc updating from time to time. Having it in the repo and release notes does make sure it's not forgotten, though adds a cost to contributors/maintainers who follow the process.

All fmt functions only accept a raw C-string as argument.
