Pull request description:
## Issue being fixed or feature implemented
Current `bestCLHeightDiff` checks are too relaxed
## What was done?
Make`bestCLHeightDiff` checks stricter
## How Has This Been Tested?
Run a node on mainnet/testet, run tests
## Breaking Changes
Old nodes aren't aware of this new logic so it's activated via `mn_rr` hardfork

Pull request description:
## Additional Information
This pull request is motivated by [bitcoin#22371](https://github.com/bitcoin/bitcoin/pull/22371), which gets rid of the `pblocktree` global.
The sole usage of `pblocktree` introduced by Dash is for managing our {address, spent, timestamp} indexes with most of invocations within `BlockManager` or `CChainState`, granting them internal access to `pblocktree` (now `m_block_tree_db`). The sole exception being `Get*Index`, that relies on accessing the global and has no direct internal access.
This pull request aims to refactor code associated with `Get*Index` with the eventual aim of moving gaining access to the global out of the function. `Get*Index` is called exclusively called through RPC, which makes giving it access to `ChainstateManager` quite easy, which makes switching from the global to accessing it through `ChainstateManager` when backporting [bitcoin#22371](https://github.com/bitcoin/bitcoin/pull/22371) a drop-in replacement.
Alongside that, the surrounding code has been given some TLC:
* Moving code out of `validation.cpp` and into `rpc/index_util.cpp`. The code is exclusively used in RPC logic and doesn't aid in validation.
* Add lock annotations for accessing `pblocktree` (while already protected by `::cs_main`, said protection is currently not enforced but will be once moved into `BlockManager` in the backport)
* `const`-ing input arguments and using pass-by-value for input arguments that can be written inline (i.e. types like `CSpentIndexKey` are still pass-by-ref).
* While `const`ing `CTxMemPool` functions were possible (courtesy of the presence of `const_iterator`s), the same is currently not possible with `CBlockTreeDB` functions as the iterator is non-`const`.
* Extend error messages to `GetSpentIndex` to bring it line with other `Get*Index`es.
* Define key-value pairings as a `*Entry` typedef and replacing all explicit type constructions with it.
* Make `CTxMemPool::getAddressIndex` indifferent to how `CMempoolAddressDeltaKey` is constructed.
* Current behaviour is to accept a `std::pair<uint160, AddressType>` and construct the `CMempoolAddressDeltaKey` internally, this was presumably done to account for the return type of `getAddressesFromParams` in the sole call for the `CTxMemPool::getAddressIndex`.
* This has been changed, moving the construction into the RPC call.
* Moving {height, timestamp} sorting out of RPC and into the applicable `Get*Index` functions.

ec0803a0f5 refactor: align `TxToUniv` argument list with upstream (Kittywhiskers Van Gogh)
Pull request description:
## Additional Information
* Closes https://github.com/dashpay/dash/issues/6000
* `TxToUniv`'s argument list needed to be rearranged to match upstream as closely as possible (i.e. placing Dash-specific arguments at the end of the list to allow for code to be backported unmodified, relying on default arguments instead of having to modify each invocation to insert the default argument in between).
This was due to a new `TxToUniv` variant being introduced in [bitcoin#20286](https://github.com/bitcoin/bitcoin/pull/20286)
* The maximum number of public keys in a multisig remains the same. The upper limit for bare multisigs is and always has been `MAX_PUBKEYS_PER_MULTISIG` ([source](19512988c6/src/script/interpreter.cpp (L1143-L1144))), which has always been 20 ([source](19512988c6/src/script/script.h (L28-L29))). The limit of up to 16 comes from P2SH overhead ([source](19512988c6/src/script/descriptor.cpp (L877-L880))) and that hasn't changed.
In effect, what [bitcoin#20867](https://github.com/bitcoin/bitcoin/pull/20867) does to Dash Core is change the error from "too many public keys" (as we'll be testing against the bare multisig limit) to "excessive redeemScript size" ([source](19512988c6/src/rpc/util.cpp (L223-L225))) (which is the _true_ limitation).
* Backporting [bitcoin#21934](https://github.com/bitcoin/bitcoin/pull/21934) required a minor change in the condition needed to emit `activation_height` as `has_signal` in the preceding block will evaluate true for both `STARTED` and `LOCKED_IN` while earlier it would only for `STARTED`.
* In [bitcoin#22722](https://github.com/bitcoin/bitcoin/pull/22722), a `self.stop_node` had to be added to account for the absurd fee warning that a new test condition introduces.
* [bitcoin#23706](https://github.com/bitcoin/bitcoin/pull/23706) is partial due to commits in it that rely on RPC type enforcement, which is currently not implemented in Dash Core.
* `feature_dip3_deterministicmns.py` depends on the reporting of `addresses` to validate multisigs containing expected payees. There is no replacement RPC call to report the pubkeys that compose a multisig address. In the interm, the `-deprecatedrpc=addresses` flag has been enabled to allow the test to run otherwise unmodified.
## Breaking Changes
* The following RPCs: `gettxout`, `getrawtransaction`, `decoderawtransaction`, `decodescript`, `gettransaction`, and REST endpoints: `/rest/tx`, `/rest/getutxos`, `/rest/block` deprecated the following fields (which are no longer returned in the responses by default): `addresses`, `reqSigs`.
The `-deprecatedrpc=addresses` flag must be passed for these fields to be included in the RPC response. Note that these fields are attributes of the `scriptPubKey` object returned in the RPC response. However, in the response of `decodescript` these fields are top-level attributes, and included again as attributes of the `scriptPubKey` object.
* When creating a hex-encoded Dash transaction using the `dash-tx` utility with the `-json` option set, the following fields: `addresses`, `reqSigs` are no longer returned in the tx output of the response.
* The error message for attempts at making multisigs with >16 pubkeys will change to an "excessive redeemScript size" instead of the previous "too many public keys".

adba60924c addrman: allow for silent overwriting of inconsistent peers.dat (Kittywhiskers Van Gogh)
fbb2b51d75 merge bitcoin#26909: prevent peers.dat corruptions by only serializing once (Kittywhiskers Van Gogh)
Pull request description:
## Additional Information
[bitcoin#22762](https://github.com/bitcoin/bitcoin/pull/22762) (backported as part of [dash#6043](https://github.com/dashpay/dash/pull/6043)) did away with then-existing behaviour of overwriting `peers.dat` silently if found corrupt with the rationale of preventing situations where the wrong file is pointed at or the file is written by a higher version of Core. Alongside a change in behaviour, refactoring also took place and further changes were built on top of them.
Since then, there have been reports of an increasing number of "Corrupt data. Consistency check failed with code -5: iostream error" errors from builds based on `develop`. Reverting the pull request that introduced this change in behaviour is non-trivial due to the number of backports that build on top of the refactoring brought along with it.
Nor were any other error messages found except for the one mentioned above. The tendency for `peers.dat` to corrupt itself has also been documented upstream ([bitcoin#26599](https://github.com/bitcoin/bitcoin/issues/26599)), with the issue marked as closed with the merger of [bitcoin#26909](https://github.com/bitcoin/bitcoin/pull/26909).
Therefore, to remedy the above problem, alongside backporting [bitcoin#26909](https://github.com/bitcoin/bitcoin/pull/26909), to avoid inconvenience, instead of reverting all progress made from backporting (as the benefits of not overwriting `peers.dat` for having the wrong magic altogether, for example, is something that doesn't need to be reverted), only inconsistent `peers.dat` files will be overwritten and the action logged with no user intervention required.

In bitcoin#20286, a new `TxToUniv` will be defined and in order to
minimize upstream deviation caused by having to change function calls
to account for `const CSpentIndexTxInfo*` being placed _before_
`const CTxUndo*` (requiring us to therefore specify `nullptr` as those
calls do not expect spend information) instead of letting the default
value remain. To allow for that, their ordering will be swapped.
To prevent a confusion with the last two arguments between the
`core_io` definition and the `rpc/blockchain` definition, let's do the
inversion here too before the backport.

Pull request description:
```
Thank you, I'll say goodbye soon
Though its the end of these globals, don't blame yourself now
And if its true, I will surround you and give life to a chainstate
That's our own
```
## Additional Information
* In `CDeterministicMN::ToJson()`, `collateralAddress` is extracted by finding the `scriptPubKey` of a transaction output for a masternode, originally this used `GetUTXOCoin` but doesn't work for spent tranasction outputs (as they're _not_ UTXOs), so in [dash#5607](https://github.com/dashpay/dash/pull/5607), a fallback was introduced that looks through the general transaction set if going through the UTXO set yielded nothing.
`GetUTXOCoin` accesses the active chainstate to get ahold of the UTXO set, this was done through globals. The removal of chainstate globals meant that whoever was calling `GetUTXOCoin` should have access to the chainstate handy. This is trivial in RPC code where `ToJson()` is used ([source](5baa522225/src/rpc/evo.cpp (L1286))) through `Ensure`(`Any`)`Chainman`. Not the case in Qt code ([source](5baa522225/src/qt/masternodelist.cpp (L369))), which is supposed to be given restricted access to information by the interface.
As the fallback seems to be capable of fetching UTXOs and spent outputs, we can remove the `GetUTXOCoin` method and make the fallback the only method.
* In `develop`, as of this writing, `CChainState` members `FlushStateToDisk` and {`Enforce`, `Invalidate`, `MarkConflicting`}`Block` were accessing their internals through the global, despite having direct access to them. As the globals they were calling are going to be bid farewell, they needed to be changed to access its members instead.
The reason for going the roundabout way is unknown.
* `CDSNotificationInterface` takes in a `ChainstateManager` (instead of the `CChainState` it actually requires) as at the time of interface initialization ([source](5baa522225/src/init.cpp (L1915-L1918))), the active chainstate hasn't been loaded in yet as that happens further down ([source](5baa522225/src/init.cpp (L1988-L1991))).
As `CDSNotificationInterface::InitializeCurrentBlockTip()` is called well after it is initialized, we can resolve to the active chainstate in there.
* As `GetCreditPoolDiffForBlock` requires access to `ChainstateManager` as `GetCreditPoolDiffForBlock` > `ProcessLockUnlockTransaction` > `CheckAssetLockUnlockTx` > `CheckAssetUnlockTx` > `ChainstateManager::m_blockman.LookupBlockIndex()` and `BlockAssembler` only has `CChainState`, it had to be reworked around `ChainstateManager`.
~~`CChainState` is passed as a direct argument while `ChainstateManager` can be fetched from `NodeContext`. Unlike `CTxMemPool`, which can be passed custom instances ([source](5baa522225/src/rpc/mining.cpp (L381-L382)), [source](5baa522225/src/test/util/setup_common.cpp (L391-L392))), `CChainState`'s argument value is taken from `NodeContext::chainstate.ActiveChainstate()` and since we're now accepting `ChainstateManager` wholesale, we can dispense with accepting `CChainState` as an argument.~~
~~Changes to that effect have been made.~~
AssumeUTXO introduces the need to be able to use different `CChainState`s, so this underlying assumption no longer holds true, the above described changes have been reverted. Asset locks code has been refactored to use `BlockManager` directly (which does come with the downside of needing to hold `cs_main` for longer than strictly necessary, this is why only asset locks uses `BlockManager` directly while other cases still benefit from having `ChainstateManager` as a whole).
* `CMNHFManager::ConnectManagers` will be taking in a `ChainstateManager` pointer due to the `GetSignalsStage` > `GetForBlock` > `ProcessBlock` > `extractSignals` > `CheckMNHFTx` > `ChainstateManager::m_blockman.LookupBlockIndex()` chain.
* The use of a bespoke `NodeContext` in `coinselector_tests` breaks tests if any interface call relies on a chainstate as `testNode` doesn't initialize one. For the most part, this was masked by `WalletTestingSetup` populating the chainstate globals from its own `NodeContext` even if the tests themselves preferred to use their own stripped down `testNode`.
Though, removing the chainstate globals meant that they can no longer rely on `WalletTestingSetup`'s `NodeContext` to mask the barebones `testNode` global being used in the test (specifically, `addCoins` > `listMNCollaterials` > `ChainActive()` worked because `ChainActive()` accessed `WalletTestingSetup`'s `NodeContext` but when `ChainActive()` was gone and replaced with `NodeContext::chainman.ActiveChain()`, it uses `testNode`'s `ChainstateManager`, which doesn't exist, which causes it to crash).
To remedy this, a5595b13 and 5e54aa9b from [bitcoin#23288](https://github.com/bitcoin/bitcoin/pull/23288) were adapted for the limited purpose of eliminating `testNode` and using `WalletTestingSetup`'s `NodeContext` instead. This comes with the unfortunate effect of skipping a lot of the refactoring, cleanups and optimizations done before and adapting the ones after them non-trivial.
It is therefore best recommended that the commit be reverted and changes implemented step-by-step in a pull request at some point in the future. For now, it's kept around here for the sake of this pull request, which, if merged, should prevent more chainstate globals use from leaking into the codebase.

## Breaking Changes
* Backporting `coinselector_tests` changes are now much more annoying.
* The following RPCs, `protx list`, `protx listdiff`, `protx info` will no longer report `collateralAddress` if the transaction index has been disabled (`txindex=0`).

adapted from a5595b13 and 5e54aa9b in bitcoin#23288. changes to
coinselector_tests must be reverted before backports related to it
are done as these changes are primarily motivated by bitcoin#21866
taking away the global chainstate, which breaks coinselector_tests and
these changes skips over a lot of backporting, making them incompatible
with backporting efforts (or even the commits its adapted from).
the existing behaviour was that it creates its own testNode but doesn't
populate it with a ChainstateManager (or much at all) while the rest of
the client uses WalletTestingSetup's values. for the longest time this
was fine because addCoins > listMNCollaterials > ChainActive() meant that
it was using the fallback, but when chainstate globals are removed,
WalletTestingSetup's values can't serve as a fallback anymore as it'd
now be looking for NodeContext::chainman::m_chain, and chainman wasn't
setup with testNode and the tests crash.
