Pull request description:

  This pull request is part of the `libbitcoinkernel` project https://github.com/bitcoin/bitcoin/issues/24303 https://github.com/bitcoin/bitcoin/projects/18 and more specifically its "Step 2: Decouple most non-consensus code from libbitcoinkernel". It is also a follow up to #26177.

  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.

refactor: Replace string chain name constants with ChainTypes
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.

refactor: Create chaintype files
This is the first of a number of commits with the goal of moving the
chain type definitions out of chainparamsbase to their own file and
implementing them as enums instead of constant strings. The goal is to
allow the kernel chainparams to no longer include chainparamsbase.

The commit is part of an ongoing effort to decouple the libbitcoinkernel
library from the ArgsManager and other functionality that should not be

Merge bitcoin/bitcoin#26076: Switch hardened derivation marker to h
fe49f06c0e91b96feb8d8f1bd478c3173f14782c doc: clarify PR 26076 release note (Sjors Provoost)
bd13dc2f46ea10302a928fcf0f53b7aed77ad260 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.

  See discussion in #15740

move-only: Extract common/args and common/config.cpp from util/system
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.

Switch hardened derivation marker to h in descriptors
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/24303 https://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.

faf3f12424fa8558e65fa3f1dd3aa1d0eea8604e refactor: Replace GetTimeMicros by SystemClock (MarcoFalke)

Pull request description:

  It is unclear from the name that `GetTimeMicros` returns the system time. Also, it is not using the type-safe `std::chrono` types.

  Fix both issues by replacing it with `SystemClock` in the only place it is used.

  This refactor should not change behavior.

Pull request description:

  There may be a theoretical deadlock for the duration of the offset when the system clock is adjusted into a past time while executing `SeedStrengthen`.

  Fix this by using steady clock.

  Do the same in `FindBestImplementation`, which shouldn't be affected, because it discards outlier measurements. However, doing the same there for consistency seems fine.

  Do the same in `FlushStateToDisk`, which should make the flushes more steady, if the system clock is adjusted by a large offset.

Pull request description:

  Add common InitConfig function to deduplicate bitcoind and bitcoin-qt code reading config files and creating the datadir.

  Noticed the duplicate code while reviewing #27073 and want to remove it because difference in bitcoin-qt and bitcoind behavior make it hard to evaluate changes like #27073

  There are a few minor changes in behavior:

  - In bitcoin-qt, when there is a problem reading the configuration file, the GUI error text has changed from "Error: Cannot parse configuration file:" to "Error reading configuration file:" to be consistent with bitcoind.
  - In bitcoind, when there is a problem reading the settings.json file, the error text has changed from "Failed loading settings file" to "Settings file could not be read" to be consistent with bitcoin-qt.
  - In bitcoind, when there is a problem writing the settings.json file, the error text has changed from "Failed saving settings file" to "Settings file could not be written" to be consistent with bitcoin-qt.
  - In bitcoin-qt, if there datadir is not accessible (e.g. no permission to read), there is an normal error dialog showing "Error: filesystem error: status: Permission denied [.../settings.json]", instead of an uncaught exception.

Merge bitcoin/bitcoin#27073: Convert ArgsManager::GetDataDir to a read-only function

56e370fbb9413260723c598048392219b1055ad0 util: add ArgsManager datadir helper functions (willcl-ark)

Pull request description:

  Fixes #20070

  Currently `ArgsManager::GetDataDir()` ensures it will always return a datadir by creating one if necessary. The function is shared between `bitcoind` `bitcoin-qt` and `bitcoin-cli` which results in the undesirable behaviour described in #20070.

  This PR splits out the part of the function which creates directories and adds it as a standalone function, only called as part of `bitcoind` and `bitcoin-qt` init, but not `bitcoin-cli`.

  `ReadConfigFiles`' behavior is changed to use the absolute path of the config file in error and warning messages instead of a relative path.

  This was inadvertantly the form being tested [here](73966f75f6/test/functional/feature_config_args.py (L287)), whilst we were _not_ testing that a relative path was returned by the message even though we passed a relative path in as argument.

Merge bitcoin/bitcoin#25943: rpc: Add a parameter to sendrawtransaction which sets a maximum value for unspendable outputs.

04f270b4358417fc2827b9f91717816062b1864e Add test for unspendable transactions and parameter 'maxburnamount' to sendrawtransaction. (David Gumberg)

Pull request description:

  This PR adds a user configurable, zero by default parameter — `maxburnamount` — to `sendrawtransaction`. This PR makes bitcoin core reject transactions that contain unspendable outputs which exceed `maxburnamount`.  closes #25899.

  As a result of this PR, `sendrawtransaction` will by default block 3 kinds of transactions:

  1. Those that begin with `OP_RETURN` - (datacarriers)
  2. Those whose lengths exceed the script limit.
  3. Those that contain invalid opcodes.

  The user is able to configure a `maxburnamount` that will override this check and allow a user to send a potentially unspendable output into the mempool.

  I see two legitimate use cases for this override:
  1. Users that deliberately use `OP_RETURN` for datacarrier transactions that embed data into the blockchain.
  2.  Users that refuse to update, or are unable to update their bitcoin core client would be able to make use of new opcodes that their client doesn't know about.
