Add a blocks_dir field to the BlockManager options. Move functions
relying on the global gArgs to get the blocks_dir into the BlockManager
class.
This should eventually allow users of the BlockManager to not rely on
the global Args and instead pass in their own options.
This is a commit in preparation for the next few commits. The functions
are moved to methods to avoid their re-declaration for the purpose of
passing in BlockManager options.
The functions that were now moved into the BlockManager should no longer
use the params as an argument, but instead use the member variable.
In the moved ReadBlockFromDisk and UndoReadFromDisk, change
the function signature to accept a reference to a CBlockIndex instead of
a raw pointer. The pointer is expected to be non-null, so reflect that
in the type.
To allow for the move of functions to BlockManager methods all call
sites require an instantiated BlockManager, or a callback to one.

* There is no rationale for it being a global function, when it acts like a member function
* `performance-unnecessary-copy-initialization` clang-tidy isn't run on it
Fix all issues by making it a member function.

It replaces pull request https://github.com/bitcoin/bitcoin/pull/27294, which just moved the constants to a new file, but did not re-declare them as enums.
The code move of the chain name constants out of the `chainparamsbase` to their own separate header allows the kernel `chainparams` to no longer include `chainparamsbase`. The `chainparamsbase` contain references to the `ArgsManager` and networking related options that should not belong to the kernel library. Besides this move, the constants are re-declared as enums with helper functions facilitating string conversions.

This is a follow-up to previous commits moving the chain constants out
of chainparamsbase.
The script removes the chainparamsbase header in all files where it is
included, but not used. This is done by filtering against all defined
symbols of the header as well as its respective .cpp file.
The kernel chainparams now no longer relies on chainparamsbase.

-END VERIFY SCRIPT-
This commit effectively moves the definition of these constants
out of the chainparamsbase to their own file.
Using the ChainType enums provides better type safety compared to
passing around strings.
The commit is part of an ongoing effort to decouple the libbitcoinkernel
library from the ArgsManager and other functionality that should not be
part of the kernel library.
fe49f06c0e doc: clarify PR 26076 release note (Sjors Provoost)
bd13dc2f46 Switch hardened derivation marker to h in descriptors (Sjors Provoost)
Pull request description:
This makes it easier to handle descriptor strings manually, especially when importing from another Bitcoin Core wallet.
For example the `importdescriptors` RPC call is easiest to use `h` as the marker: `'["desc": ".../0h/..."]'`, avoiding the need for escape characters. With this change `listdescriptors` will use `h`, so you can copy-paste the result, without having to add escape characters or switch `'` to 'h' manually.
Both markers can still be parsed.
The `hdkeypath` field in `getaddressinfo` is also impacted by this change, except for legacy wallets. The latter is to prevent accidentally breaking ancient software that uses our legacy wallet.

OBJ_NAMED_PARAMS type works the same as OBJ type except it registers the object
keys to be accepted as top-level named-only RPC parameters. Generated
documentation also lists the object keys seperately in a new "Named arguments"
section of help text.
Named-only RPC parameters have the same semantics as python keyword-only
arguments (https://peps.python.org/pep-3102/). They are always required to be
passed by name, so they don't affect interpretation of positional arguments,
and aren't affected when positional arguments are added or removed.
The new OBJ_NAMED_PARAMS type is used in the next commit to make it easier to
pass options values to various RPC methods.

ac463e87df [test util] mock mempool minimum feerate (glozow)
Pull request description:
Part of package relay, see #27463.
Note that this still allows packages to bump transactions that are below the dynamic mempool minimum feerate, which means this still solves the "mempool is congested and my presigned 1sat/vB tx is screwed" problem for all transactions.
On master, the package policy (only accessible through regtest-only RPC submitpackage) allows 0-fee (or otherwise below min relay feerate) transactions if they are bumped by a child. However, with default package limits, we don't yet have a DoS-resistant way of ensuring these transactions remain bumped throughout their time in the mempool. Primarily, the fee-bumping child may later be replaced by another transaction that doesn't bump the parent(s). The parent(s) could potentially stay bumped by other transactions, but not enough to ever be selected by the `BlockAssembler` (due to `blockmintxfee`).
For example, (tested [here](https://github.com/glozow/bitcoin/commits/26933-motivation)):
- The mempool accepts 24 below-minrelayfeerate transactions ("0-fee parents"), all bumped by a single high-fee transaction ("the fee-bumping child"). The fee-bumping child also spends a confirmed UTXO.
- Two additional children are added to each 0-fee parent. These children each pay a feerate slightly above the minimum relay feerate (e.g. 1.9sat/vB) such that, for each 0-fee parent, the total fees of its two children divided by the total size of the children and parent is above the minimum relay feerate.
- If a block template is built now, all transactions would be selected.
- A transaction replaces the the fee-bumping child, spending only the confirmed UTXO and not any of the outputs from the 0-fee parents.
- The 0-fee parents now each have 2 children. Their descendant feerates are above minrelayfeerate, which means that they remain in the mempool, even if the mempool evicts all below-minrelayfeerate packages.
- If a block template is built now, none of the 0-fee parents or their children would be selected.
- Even more low-feerate descendants can be added to these below-minrelayfeerate packages and they will not be evicted until they expire or the mempool reaches capacity.
Unless we have a DoS-resistant way of ensuring package CPFP-bumped transactions are always bumped, allowing package CPFP to bump below-minrelayfeerate transactions can result in these problematic situations. See #27018 which proposes a partial solution with some limitations, and contains discussion about potential improvements to eviction strategy. While no adequate solution exists, for now, avoid these situations by requiring all transactions to meet min relay feerate.

Pull request description:
A memory resource similar to `std::pmr::unsynchronized_pool_resource`, but optimized for node-based containers. The goal is to be able to cache more coins with the same memory usage, and allocate/deallocate faster.
This is a reimplementation of #22702. The goal was to implement it in a way that is simpler to review & test
* There is now a generic `PoolResource` for allocating/deallocating memory. This has practically the same API as `std::pmr::memory_resource`. (Unfortunately I cannot use std::pmr because libc++ simply doesn't implement that API).
* Thanks to sipa there is now a fuzzer for PoolResource! On a fast machine I ran it for ~770 million executions without finding any issue.
* The estimation of the correct node size is now gone, PoolResource now has multiple pools and just needs to be created large enough to have space for the unordered_map nodes.
I ran benchmarks with #22702, mergebase, and this PR. Frequency locked Intel i7-8700, clang++ 13.0.1 to reindex up to block 690000.
```sh
bitcoind -dbcache=5000 -assumevalid=00000000000000000002a23d6df20eecec15b21d32c75833cce28f113de888b7 -reindex-chainstate -printtoconsole=0 -stopatheight=690000
```
The performance is practically identical with #22702, just 0.4% slower. It's ~21% faster than master:
Note that on cache drops mergebase's memory doesnt go so far down because it does not free the `CCoinsMap` bucket array.

Along the way, it refactors the function to deduplicate the logic, updates the local variables to match modern conventions, adds test coverage for both the new and existing `Select` logic, and adds bench tests for the worst case performance of both the new and existing `Select` logic.
This functionality is used in the parent PR.

This is an extraction of ArgsManager related functions from util/system
into their own common file.
Config file related functions are moved to common/config.cpp.
The background of this commit is an ongoing effort to decouple the
libbitcoinkernel library from the ArgsManager. The ArgsManager belongs
into the common library, since the kernel library should not depend on
it. See doc/design/libraries.md for more information on this rationale.
`evhttp_uri_parse` can return a nullptr, for example when the URI
contains invalid characters (e.g. "%").
`GetQueryParameterFromUri` passes the output of `evhttp_uri_parse`
straight into `evhttp_uri_get_query`, which means that anyone calling
a REST endpoint in which query parameters are used (e.g. `rest_headers`)
can cause a segfault.
This bugfix is designed to be minimal and without additional behaviour change.
Follow-up work should be done to resolve this in a more general and robust way,
so not every endpoint has to handle it individually.
Avoid adding transactions below min relay feerate because, even if they
were bumped through CPFP when entering the mempool, we do not have a
DoS-resistant way of ensuring they always remain bumped. In the future,
this rule can be relaxed (e.g. to allow packages to bump 0-fee
transactions) if we find a way to do so.
3153e7d779 [fuzz] Add HeadersSyncState target (dergoegge)
53552affca [headerssync] Make m_commit_offset protected (dergoegge)
Pull request description:
This adds a fuzz target for the `HeadersSyncState` class.
I am unsure how well this is able to cover the logic since it is just processing unserialized CBlockHeaders straight from the fuzz input (headers are sometimes made continuous). However, it does manage to get to the redownload phase so i thought it is better then not having fuzzing at all.
It would also be nice to fuzz the p2p logic that is using `HeadersSyncState` (e.g. `TryLowWorkHeadersSync`, `IsContinuationOfLowWorkHeadersSync`) but that likely requires some more work (refactoring👻).

This makes it easier to handle descriptor strings manually. E.g. an RPC call that takes an array of descriptors can now use '["desc": ".../0h/..."]'.
Both markers can still be parsed. The default for new descriptors is changed to h. In normalized form h is also used. For private keys the chosen marker is preserved in a round trip.
The hdkeypath field in getaddressinfo is also impacted by this change.

Pull request description:
This pull request is part of the `libbitcoinkernel` project https://github.com/bitcoin/bitcoin/issues/24303https://github.com/bitcoin/bitcoin/projects/18 and more specifically its "Step 2: Decouple most non-consensus code from libbitcoinkernel". This commit was originally authored by empact and is taken from its parent PR #25152.
#### Context
There is an ongoing effort to decouple the `ArgsManager` used for command line parsing user-provided arguments from the libbitcoinkernel library (https://github.com/bitcoin/bitcoin/pull/25290, https://github.com/bitcoin/bitcoin/pull/25487, https://github.com/bitcoin/bitcoin/pull/25527, https://github.com/bitcoin/bitcoin/pull/25862, https://github.com/bitcoin/bitcoin/pull/26177, and https://github.com/bitcoin/bitcoin/pull/27125). The `ArgsManager` is defined in `system.h`. A similar pull request extracting functionality from `system.h` has been merged in https://github.com/bitcoin/bitcoin/pull/27238.
#### Changes
Next to providing better code organization, this PR removes some reliance of the tree of libbitcoinkernel header includes on `system.h` (and thus the `ArgsManager` definition) by moving filesystem related functions out of the `system.*` files.
There is already a pair of `fs.h` / `fs.cpp` in the top-level `src/` directory. They were not combined with the files introduced here, to keep the patch cleaner and more importantly because they are often included without the utility functions. The new files are therefore named `fs_helpers` and the existing `fs` files are moved into the util directory.
Further commits splitting more functionality out of `system.h` are still in #25152 and will be submitted in separate PRs once this PR has been processed.

faf8dc496e fuzz: Remove legacy int parse fuzz tests (MarcoFalke)
Pull request description:
The fuzz tests checked that the result of the new function was equal to the legacy function. (Side note: The checks were incomplete, as evident by the follow-up fix in commit b5c9bb5cb9).
Given that they haven't found any issues in years (beside missing the above issue, that they couldn't catch), it seems time to remove them.
They may come in handy in the rare case that someone would want to modify `LocaleIndependentAtoi()` or `Parse*Int*()`, however that seems unlikely. Also, appropriate checks can be added then.
