Pull request description:
Overall PR: #20158 (tree-wide: De-globalize ChainstateManager)
Based on:
- [x] #21270 | [Bundle 4/n] Prune g_chainman usage in validation-adjacent modules
- [x] #21525 | [Bundle 4.5/n] Followup fixups to bundle 4
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`

Seems odd to have an option for non-deterministic tests
when the goal should be for all tests to be deterministic.

1a6323bdbe doc: update developer notes for removal of MakeUnique (fanquake)
3ba2840e7e scripted-diff: remove MakeUnique<T>() (fanquake)
Pull request description:
Since requiring C++17, this is just pointless abstraction. I think we should just "tear the band-aid off" and remove it. Similar to the changes happening in #21366.
Also, having a comment saying this is deprecated doesn't prevent it's usage in new code. i.e : https://github.com/bitcoin/bitcoin/pull/20946#discussion_r561949731.
The repository is fairly quiet at the moment, so any potential complaints about having to rebase should be minimal. Might as well get this over and done with.

b4511e2e2e log: Prefix log messages with function name if -logsourcelocations is set (practicalswift)
Pull request description:
Prefix log messages with function name if `-logfunctionnames` is set.
Yes, exactly like `-logthreadnames` but for function names instead of thread names :)
This is a small developer ergonomics improvement: I've found this to be a cheap/simple way to correlate log output and originating function.
For me it beats the ordinary cycle of 1.) try to figure out a regexp matching the static part of the dynamic log message, 2.) `git grep -E 'Using .* MiB out of .* requested for signature cache'`, 3.) `mcedit filename.cpp` (`openemacs filename.cpp` works too!) and 4.) search for log message and scroll up to find the function name :)
Without any logging parameters:

dc8be12510 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.

Previously, the validation_chainstatemanager_tests test suite
instantiated its own duplicate ChainstateManager on which tests were
performed.
This wasn't a problem for the specific actions performed in
that suite. However, the existence of this duplicate ChainstateManager
and the fact that many of our validation static functions reach for
g_chainman, ::Chain(state|)Active means we may end up acting on two
different CChainStates should we write more extensive tests in the
future.
This change adds a new ChainTestingSetup which performs all
initialization previously done by TestingSetup except:
1. RPC command registration
2. ChainState initialization
3. Genesis Activation
4. {Ban,Conn,Peer}Man initialization
Means that we will no longer need to initialize a duplicate
ChainstateManger in order to test the initialization codepaths of
CChainState and ChainstateManager.
Lastly, this change has the additional benefit of allowing for
review-only assertions meant to show correctness to work in future work
de-globalizing g_chainman.
In the test chainstatemanager_rebalance_caches, an additional
LoadGenesisBlock call is added as MaybeReblanaceCaches eventually calls
FlushBlockFile, which tries to access vinfoBlockFile[nLastBlockFile],
which is out of bounds when LoadGenesisBlock hasn't been called yet.
-----
Note for the future:
The class con/destructor inheritance structure we have for these
TestingSetup classes is probably not the most suitable abstraction. In
particular, for both TestingSetup and ChainTestingSetup, we need to stop
the scheduler first before anything else. Otherwise classes depending on
the scheduler may be referenced by the scheduler after said classes are
freed. This means that there's no clear parallel between our teardown
code and C++'s destructuring order for class hierarchies.
Future work should strive to coalesce (as much as possible) test and
non-test init codepaths and perhaps structure it in a more fail-proof
way.
This moves the CBlockPolicyEstimator to the NodeContext, which get rids
of two globals and allows us to conditionally create the
CBlockPolicyEstimator (and to remove a circular dep).

Since m_check_ratio is only set once and since the CTxMemPool object is
no longer a global variable, m_check_ratio can be passed into the
constructor of CTxMemPool. Since it is only read from after
initialization, m_check_ratio can also be made a const and hence no
longer needs to be guarded by the cs mutex.

PeerLogicValidation was originally net_processing's implementation to
the validation interface. It has since grown to contain much of
net_processing's logic. Therefore rename it to reflect its
responsibilities.
Suggested in
https://github.com/bitcoin/bitcoin/pull/10756#pullrequestreview-53892618.
Keep a references to chainparams, rather than calling the global
Params() function every time it's needed. This is fine, since
globalChainParams does not get updated once it's been set, and it's
available at the point of constructing the PeerLogicValidation object.

fa33bc2dab init: Capture copy of blocknotify setting for BlockNotifyCallback (MarcoFalke)
fa40017706 init: Pass reference to ArgsManager around instead of relying on global (MarcoFalke)
Pull request description:
The gArgs global has several issues:
* gArgs is used by each process (bitcoind, bitcoin-qt, bitcoin-wallet, bitcoin-cli, bitcoin-tx, ...), but it is hard to determine which arguments are actually used by each process. For example arguments that have never been registered, but are still used, will always return the fallback value.
* Tests may run several sub-tests, which need different settings. So globals will have to be overwritten, but that is fragile on its own: e.g. https://github.com/bitcoin/bitcoin/pull/19704#issuecomment-678259092 or #19511
The goal is to remove gArgs, but as a first step in that direction this pull will change gArgs in init to use a passed-in reference instead.

Hold a reference to connman rather than a pointer because:
- PeerLogicValidation can't run without a connman
- The pointer never gets reseated
The alternative is to always assert that the pointer is non-null before
dereferencing.
Change the name from connman to m_connman at the same time to conform
with current style guidelines.

Pull request description:
This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11):
Parent PR: #15606
Issue: #15605
Specification: https://github.com/jamesob/assumeutxo-docs/tree/master/proposal
---
In the assumeutxo implementation draft (#15056), once a UTXO snapshot is loaded, a new chainstate object is created after initialization. This means that we have to reclaim some of the cache that we've allocated to the original chainstate (per `dbcache=`) to repurpose for the snapshot chainstate.
Furthermore, it makes sense to have different cache allocations depending on which chainstate is more active. While the snapshot chainstate is working to get to the network tip (and the background validation chainstate is idle), it makes sense that the snapshot chainstate should have the majority of cache allocation. And contrariwise once the snapshot has reached network tip, most of the cache should be given to the background validation chainstate.
This set of changes (detailed in the commit messages) allows us to dynamically resize the various coins caches. None of the functionality introduced here is used at the moment, but will be in the next AU PR (which introduces `ActivateSnapshot`).
`ChainstateManager::MaybeRebalanceCaches()` defines the (somewhat normative) cache allocations between the snapshot and background validation chainstates. I'd be interested in feedback if anyone has thoughts on the proportions I've set there.
