This creates a cleaner interface with ATMP, allows us to make results const,
and makes accessing values that don't make sense (e.g. fee when tx is
invalid) an error.

dc8be12510c2fd5a809d9a82d2c14b464b5e5a3f refactor: remove boost::thread_group usage (fanquake)
Pull request description:
Post #18710, there isn't much left using `boost::thread_group`, so should just be able to replace it with the standard library. This also removes the last use of `boost::thread_interrupted`.
After this change, last piece of Boost Thread we'd be using is `boost::shared_mutex`. See the commentary [here](https://github.com/bitcoin/bitcoin/issues/16684#issuecomment-726214696) as to why it may be non-trivial to swap that for `std::shared_mutex` in the near future.

Pull request description:
Overall PR: #20158 (tree-wide: De-globalize ChainstateManager)
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`

LoadExternalBlockFile mainly acts on CChainState.

that one since it can be expressed nicely as a scripted-diff.

fa99e33aebed0109630474e11183b0726b410c2e fuzz: move-only FillNode implementation to cpp file (MarcoFalke)
Pull request description:
This fixes a fuzz bug introduced in #20881. Previously the nodes in the fuzz tests had their version initialized to a constant (`PROTOCOL_VERSION`). After #20881, the nodes have their version initialized to an arbitrary signed integer. This is problematic for several reasons:
* Both `nVersion` and `m_greatest_common_version` may be initialized to `0`. If a `version` message is processed, this leads to a crash, because `m_greatest_common_version` must be `INIT_PROTO_VERSION` while the `version` message is processed. See #20138
* The "valid" range for `nVersion` is `[MIN_PEER_PROTO_VERSION, std::numeric_limits<int32_t>::max()]` (see check in net_processing)
* The "valid" range for `m_greatest_common_version` is `std::min(nVersion, PROTOCOL_VERSION)` (see net_processing)
Fix all issues by initializing `nVersion` and `m_greatest_common_version` to their valid ranges.

Previously, the {Basic,}TestingSetup for fuzzers were set up in many ways:
1. Calling InitializeFuzzingContext, which implicitly constructs a static
const BasicTestingSetup
2. Directly constructing a static const BasicTestingSetup in the initialize_*
function
3. Directly constructing a static TestingSetup and reproducing the
initialization arguments (I'm assuming because
InitializeFuzzingContext only initializes a BasicTestingSetup)
The new, relatively-simple MakeFuzzingContext function allows us to
consolidate these methods of initialization by being flexible enough to
be used in all situations. It:
1. Is templated so that we can choose to initialize any of
the *TestingSetup classes
2. Has sane defaults which are often used in fuzzers but are also
easily overridable
3. Returns a unique_ptr, explicitly transferring ownership to the caller
to deal with according to its situation
```
~~Question for fuzzing people: was it intentional that `src/test/fuzz/net.cpp` would directly instantiate the `BasicTestingSetup` and thus omit the `"-nodebuglogfile"` flag?~~ [Answered](https://github.com/bitcoin/bitcoin/pull/20946#issuecomment-761537108)

This adds better test coverage and will make it easier in #20744 to remove our dependency on the two-argument boost::filesystem::absolute() function which does not have a direct equivalent in C++17.
fa0a864b383a794910cdb215bb836dae12357bc6 fuzz: Use mocktime in process_message* fuzz targets (MarcoFalke)
Pull request description:
Use mocktime to allow time to advance deterministically during execution of a fuzz input. This also allows to drop the call to `JumpOutOfIbd`.

fa75d40ef866ef9ff8dc115e239ca6763aa23b06 fuzz: Introduce CallOneOf helper to replace switch-case (MarcoFalke)
Pull request description:
The current `switch (fuzzed_data_provider.ConsumeIntegralInRange<int>(0, nn)) { case 0: ... case 1: ... case nn: ...` has several problems:
* It makes it hard to review newly added targets, because it requires manual counting of cases
* It makes it hard to update a target, because updating all case labels is trivial, but tedious to review and causes merge conflicts
* ~~Updating the target raises the question whether the case labels should be preserved to not invalidate the existing fuzz inputs format. Fuzz input format might already change implicitly on every commit, so this isn't something worthwhile to pursue.~~ Edit: This pull doesn't fix this problem.
Fix all issues by adding a new `CallOneOf` helper
