refactor: Remove defunct attributes.h includes
Since the removal of NODISCARD in 81d5af42f4dba5b68a597536cad7f61894dc22a3,
the only attributes def is LIFETIMEBOUND, and it's included in many more
places that it is used.

This removes all includes which do not have an associated use of LIFETIMEBOUND,
and adds it to the following files, due to their use of the same:
* src/validationinterface.h
* src/script/standard.h

Pull request description:

  It seems confusing to pass chain params, consensus params, or a time function around when it is not needed.

  Fix this by:

  * Inlining the passed time getter function. I don't see a use case why this should be mockable.
  * Using `chainman.GetConsensus()` or `chainman.GetParams()`, where possible.

fac6cfc50f65c610f2df9af3ec2efff5eade6661 refactor: Change * to & in MutableTransactionSignatureCreator (MarcoFalke)

Pull request description:

  The `MutableTransactionSignatureCreator` constructor takes in a pointer to a mutable transaction. This is problematic for several reasons:

  * It would be undefined behaviour to pass in a nullptr because for signature creation, the memory of the mutable transaction is accessed
  * No caller currently passes in a nullptr, so passing a reference as a pointer is confusing

  Fix all issues by replacing `*` with `&` in `MutableTransactionSignatureCreator`

Base32/base64 are mechanisms for encoding binary data. That they'd
decode to a string is just bizarre. The fact that they'd do that
based on the type of input arguments even more so.

Merge bitcoin/bitcoin#22953: refactor: introduce single-separator split helper (boost::split replacement)

9cc8e876e412056ed22d364538f0da3d5d71946d refactor: introduce single-separator split helper `SplitString` (Sebastian Falbesoner)

Pull request description:

  This PR adds a simple string split helper `SplitString` that takes use of the spanparsing `Split` function that was first introduced in #13697 (commit fe8a7dcd78cfeedc9a7c705e91384f793822912b). This enables to replace most calls to `boost::split`, in the cases where only a single separator character is used. Note that while previous attempts to replace `boost::split` were controversial (e.g. #13751), this one has a trivial implementation: it merely uses an internal helper (that is unit tested and in regular use with output descriptiors) and converts its result from spans to strings. As a drawback though, not all `boost::split` instances can be tackled.

  As a possible optimization, one could return a vector of `std::string_view`s (available since C++17) instead of strings, to avoid copies. This would need more carefulness on the caller sites though, to avoid potential lifetime issues, and it's probably not worth it, considering that none of the places where strings are split are really performance-critical.

    Code review ACK a62e84438d27ee6213219fe2c233e58814fcbb5d. Ran all tests. I also like that with `boost::split` it was not obvious that the resulting container was cleared, and with `SplitString` API that's obvious.

Pull request description:

  The asmap data is currently owned by addrman, but is used by both addrman and connman. #22791 made the data const and private (so that it can't be updated by other components), but it is still passed out of addrman as a reference to const, and used by `CNetAddress` to calculate the group and AS of the net address.

  This RFC PR proposes to move all asmap data and logic into a new `NetGroupManager` component. This is initialized at startup, and the client components addrman and connman simply call `NetGroupManager::GetGroup(const CAddress&)` and `NetGroupManager::GetMappedAS(const CAddress&)` to get the net group and AS of an address.

  Part of #22290, aka [Package Mempool Accept](https://gist.github.com/glozow/dc4e9d5c5b14ade7cdfac40f43adb18a).

  This enables CPFP fee bumping in child-with-unconfirmed-parents packages by introducing [package feerate](https://gist.github.com/glozow/dc4e9d5c5b14ade7cdfac40f43adb18a#fee-related-checks-use-package-feerate) (total modified fees divided by total virtual size) and using it in place of individual feerate. We also always [validate individual transactions first](https://gist.github.com/glozow/dc4e9d5c5b14ade7cdfac40f43adb18a#always-try-individual-submission-first) to avoid incentive-incompatible policies like "parents pay for children" or "siblings pay for siblings" behavior.

Pull request description:

  Miniscript is a language for writing (a subset of) Bitcoin Scripts in a structured way.

  Miniscript permits:
  - To safely extend the Output Descriptor language to many more scripting features thanks to the typing system (composition).
  - Statical analysis of spending conditions, maximum spending cost of each branch, security properties, third-party malleability.
  - General satisfaction of any correctly typed ("valid" [0]) Miniscript. The satisfaction itself is also analyzable.
  - To extend the possibilities of external signers, because of all of the above and since it carries enough metadata.

  Miniscript guarantees:
  - That for any statically-analyzed as "safe" [0] Script, a witness can be constructed in the bounds of the consensus and standardness rules (standardness complete).
  - That unless the conditions of the Miniscript are met, no witness can be created for the Script (consensus sound).
  - Third-party malleability protection for the satisfaction of a sane Miniscript, which is too complex to summarize here.

  For more details around Miniscript (including the specifications), please refer to the [website](https://bitcoin.sipa.be/miniscript/).

  Miniscript was designed by Pieter Wuille, Andrew Poelstra and Sanket Kanjalkar.
  This PR is an updated and rebased version of #16800. See [the commit history of the Miniscript repository](https://github.com/sipa/miniscript/commits/master) for details about the changes made since September 2019 (TL;DR: bugfixes, introduction of timelock conflicts in the type system, `pk()` and `pkh()` aliases, `thresh_m` renamed to `multi`, all recursive algorithms were made non-recursive).

  This PR is also the first in a series of 3:
  - The first one (here) integrates the backbone of Miniscript.
  - The second one (#24148) introduces support for Miniscript in Output Descriptors, allowing for watch-only support of Miniscript Descriptors in the wallet.
  - The third one (#24149) implements signing for these Miniscript Descriptors, using Miniscript's satisfaction algorithm.

  Note to reviewers:
  - Miniscript is currently defined only for P2WSH. No Taproot yet.
  - Miniscript is different from the policy language (a high-level logical representation of a spending policy). A policy->Miniscript compiler is not included here.
  - The fuzz target included here is more interestingly extended in the 3rd PR to check a script's satisfaction against `VerifyScript`. I think it could be further improved by having custom mutators as we now have for multisig (see https://github.com/bitcoin/bitcoin/issues/23105). A minified corpus of Miniscript Scripts is available at https://github.com/bitcoin-core/qa-assets/pull/85.

  [0] We call "valid" any correctly-typed Miniscript. And "safe" any sane Miniscript, ie one whose satisfaction isn't malleable, which requires a key for any spending path, etc..

f59bee3fb242c9e02781a35272cf9644f37e7fc1 fuzz: execute each file in dir without fuzz engine (Anthony Towns)

Pull request description:

  Phony fuzzing (phuzzing)! Run the fuzz testing code against known inputs to detect errors. Advantage is you can easily test using the existing qa-assets datasets without having to compile with fuzzing enabled; disadvantage is that it doesn't do any actual fuzzing.

  Example usage:

  ```
  $ for a in ${QA_ASSETS}/fuzz_seed_corpus/*; do echo ${a##*/}; done | xargs -P8 -I {} /bin/sh -c "FUZZ={} test/fuzz/fuzz ${QA_ASSETS}/fuzz_seed_corpus/{}"
  No fuzzer for address_deserialize.
  No fuzzer for addrdb.
  No fuzzer for banentry_deserialize.
  addition_overflow: succeeded against 848 files in 0s.
  asmap: succeeded against 981 files in 0s.
  checkqueue: succeeded against 211 files in 0s.
  ...
  ```

  (`-P8` says run 8 of the tasks in parallel)

  If there are failures, the first one will be reported and the program will abort with output like:

  ```
  fuzz: test/fuzz/versionbits.cpp:336: void (anonymous namespace)::versionbits_fuzz_target(FuzzBufferType): Assertion `exp_state != ThresholdState::FAILED' failed.
  Error processing seed "corpus/versionbits/35345ae8e722234095810b1117a29b63af7621af"
  ```

  Rebase of #22763, which was a rebase of #21496, but also reports the name of the fuzzer and the time taken.

  Fixes #21461

Pull request description:

  The target is still one of the slowest ones, but doesn't seem incredibly important. Especially for sizes larger than the standard tx size.

  Fix that by limiting the script size.

97208634b96f2d9a55f2ead7b0ef407da729d7bd net: open p2p connections to nodes that listen on non-default ports (Vasil Dimov)

Pull request description:

  By default, for mainnet, the p2p listening port is 8333. Bitcoin Core
  has a strong preference for only connecting to nodes that listen on that
  port.

  Remove that preference because connections over clearnet that involve
  port 8333 make it easy to detect, analyze, block or divert Bitcoin p2p
  traffic before the connection is even established (at TCP SYN time).

  For further justification see the OP of:
  https://github.com/bitcoin/bitcoin/pull/23306
