fa69a5f4b76a4e2a02db6c32d9c3311ce5fe29bd util: Treat Assume as Assert when evaluating at compile-time (MarcoFalke)
Pull request description:
There is no downside or cost of treating an `Assume` at compile-time as an `Assert` and it may even help to find bugs while compiling without `ABORT_ON_FAILED_ASSUME`.
This is also required for https://github.com/bitcoin/bitcoin/pull/31093

Pull request description:
Part of cluster mempool: #30289
This adds:
* `DepGraph::AddDependencies` to add 0 or more dependencies to a single transaction at once (identical to calling `DepGraph::AddDependency` once for each, but more efficient).
* `DepGraph::RemoveTransactions` to remove 0 or more transactions from a depgraph.
* `DepGraph::GetReducedParents` (and `DepGraph::GetReducedChildren`) to get the (reduced) direct parents and children of a transaction in a depgraph.
After which, the `Cluster` type is removed.
This is the result of fleshing out the design for the "intermediate layer" ("TxGraph", no PR yet) between the cluster linearization layer and the mempool layer. My earlier thinking was that TxGraph would store `Cluster` objects (vectors of pairs of `FeeFrac`s and sets of parents), and convert them to `DepGraph` on the fly whenever needed. However, after more consideration, it seems better to have TxGraph store `DepGraph` objects, and manipulate them directly without constantly re-creating them. This requires `DepGraph` to have some additional functionality.
The bulk of the complexity here is the addition of `DepGraph::RemoveTransactions`, which leaves the remaining transactions' positions within the `DepGraph` untouched (we want existing identifiers to remain valid), so this implies that graphs can now have "holes" (positions that are unused, but followed by positions that are used). To enable that, an extension of the fuzz/test serialization format `DepGraphFormatter` is included to deal with such holes.

This commits introduces support in DepGraph for the transaction positions to be
non-continuous. Specifically, it adds:
* DepGraph::RemoveTransactions which removes 0 or more positions from a DepGraph.
* DepGraph::Positions() to get a set of which positions are in use.
* DepGraph::PositionRange() to get the highest used position in a DepGraph + 1.
In addition, it extends the DepGraphFormatter format to support holes in a
compatible way (it serializes non-holey DepGraphs identically to the old code,
and deserializes them the same way)
This adds an utility header with two functions that will be needed for
PCP, `QueryDefaultGateway` and `GetLocalAddresses`.

Pull request description:
Fixes#30833.
Instead of relying on frequent `ftell` calls (which appear to cause a significant slowdown on some systems) in XOR-enabled `AutoFile`s, cache the file position within `AutoFile` itself.

Pull request description:
This PR introduces a new CMake-based build system, which is a drop-in replacement for the current Autotools-based build system.
ML announcement: https://groups.google.com/g/bitcoindev/c/hgKkfQWzrTo
As discussed during the recent CoreDev meetup in April, the switch from Autotools to CMake is intended to happen as soon as possible after branching 28.x off, which means that 29.0 will be built using CMake.
This PR branch is essentially the [staging branch](https://github.com/hebasto/bitcoin/tree/cmake-staging), with every change reviewed and tested by a group of contributors, including (in alphabetical order):
- [**achow101**](https://github.com/achow101)

Reviewing in a separate staging repo was suggested in https://github.com/bitcoin/bitcoin/pull/27060#issuecomment-1431798320.
The accompanying changes to the OSS-Fuzz project are available in https://github.com/hebasto/oss-fuzz/pull/8.
Please refer to the [build options parity table](https://gist.github.com/hebasto/2ef97d3a726bfce08ded9df07f7dab5e). The "auto" value is no longer available; non-default values must be specified explicitly. Additionally, the new default values have been chosen to suit the everyday build experience for the majority of developers.
System requirements for using the CMake-based build system:
- CMake >= 3.22 (if not available in your system's repository, it can be downloaded from https://cmake.org/download/)
- a build tool of your choice:
- any Make (GNU Make is no longer a requirement); GNU Make is still required to build depends
- Ninja (https://ninja-build.org/)
- MSBuild
- Xcode
A note for Windows users: The default installation of the latest version of MSVC 17.10.4 includes both CMake 3.28.3 and the vcpkg package manager).
---
We, the build system developers, kindly ask reviewers to refrain from making suggestions that are not directly related to the migration process or can be implemented separately. Bugs in the scripts and errors in the updated documentation should be the focus of this PR. Please be advised that comments not aligned with this PR's goal may be ignored.
Thank you all for your understanding.

Specifically, it tries to recover from length-mismatches, recover from untrimmed whitespace, 0x-prefix and garbage at the end, instead of simply requiring exactly 64 hex-only characters. _(see also #30532)_
This PR carves out the few `uint256S` callsites that may potentially prove a bit more controversial to change because they deal with user input and backwards incompatible behaviour change.
The main behaviour change introduced in this PR is:
- `-minimumchainwork` will raise an error when input is longer than 64 hex digits
- `-assumevalid` will raise an error when input contains invalid hex characters, or when it is longer than 64 hex digits
- test: the optional RANDOM_CTX_SEED env var will now cause tests to abort when it contains invalid hex characters, or when it is longer than 64 hex digits
After this PR, the remaining work to remove `uint256S` completely is almost entirely mechanical and/or test related. I will open that PR once #30560 is merged because it builds on that.

Code review ACK 18d65d27726bf9fc7629b8e794047a10c9cf6156. Very nice change that cleans up the API, adds checking for invalid values, makes parsing of values more consistent, and adds test coverage.

Pull request description:
To supplement the [ongoing conceptual discussion about a testnet reset](https://groups.google.com/g/bitcoindev/c/9bL00vRj7OU/m/9yCPo3uUBwAJ) I have drafted a move to v4 including a fix to the difficulty adjustment mechanism, which was part of the motivation that started the discussion.
Conceptual considerations:
- The conceptual discussion about doing a testnet4 or softforking the fix into testnet3 is outside of the scope of this PR and I would ask reviewers to contribute their opinions on this on the ML instead. However, I am happy to adapt this PR to a softfork change on testnet3 if there is consensus for that instead.
- The difficulty adjustment fix suggested here touches the `CalculateNextWorkRequired` function and uses the same logic used in `GetNextWorkRequired` to find the last previous block that was not mined with difficulty 1 under the exceptionf. An alternative fix briefly mentioned on the mailing list by Jameson Lopp would be to "restrict the special testnet minimum difficulty rule so that it can't be triggered on the block right before a difficulty retarget". That would also fix the issue but I find my suggestion here a bit more elegant.

fa18fc705084f3620be566d8c6639b29117ccf68 log: Remove NOLINT(bitcoin-unterminated-logprintf) (MarcoFalke)
Pull request description:
`NOLINT(bitcoin-unterminated-logprintf)` is used to document a missing trailing `\n` char in the format string. This has many issues:
* It is just documentation, assuming that a trailing `\n` ends up in the formatted string. It is not enforced at compile-time, so it is brittle.
* If the newline was truly missing and `NOLINT(bitcoin-unterminated-logprintf)` were used to document a "continued" line, the log stream would be racy/corrupt, because any other thread may inject a log message in the meantime.
* If the newline was accidentally missing, nothing is there to correct the mistake.
* The intention of all code is to always end a log line with a new line. However, historic code exists to deal with the case where the new line was missing (`m_started_new_line`). This is problematic, because the presumed dead code has to be maintained (https://github.com/bitcoin/bitcoin/pull/30386#discussion_r1682963306).
Fix almost all issues by removing the `NOLINT(bitcoin-unterminated-logprintf)`, ensuring that a new line is always present.
A follow-up will remove the dead logging code.

Prior to this, passing string_view::data() into uint256S() meant the latter would only receive the a naked char* pointer and potentially scan past the string_view::length() until it found a null terminator (or some other non-hex character).
Appears to have been a fully dormant bug as callers were either passing a string literal or std::string directly to TxidFromFromString(), meaning null terminator always existed at pointer[length()]. Bug existed since original merge of TxidFromString(), discussed in https://github.com/bitcoin/bitcoin/pull/28922#discussion_r1404437378.

Pull request description:
Prior to C++20, `modernize-use-equals-default` could have been problematic because it could turn a non-aggregate into an aggregate. The risk would be that aggregate initialization would be enabled where the author did not intend to enable it.
With C++20, aggregate for those is forbidden either way. (https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p1008r1.pdf)
So enabled it for code clarity, consistency, and possibly unlocking compiler optimizations. See https://clang.llvm.org/extra/clang-tidy/checks/modernize/use-equals-default.html

This PR picks up #26088 by aureleoules which adds a bitcoind launch option `-rpccookieperms` to set the file permissions of the cookie generated by bitcoin core.
Example usage to make the generated cookie group-readable: `./src/bitcoind -rpccookieperms=group`.
Accepted values for `-rpccookieperms` are `[owner|group|all]`. We let `fs::perms` handle platform-specific permissions changes.

Pull request description:
Remove `fees.h`, `errors.h`, and `spanparsing.h` from the util library. Specifically:
- Move `Split` functions from `util/spanparsing.h` to `util/string.h`, using `util` namespace for clarity.
- Move remaining spanparsing functions to `script/parsing.h` since they are used for descriptor and miniscript parsing.
- Combine `util/fees.h` and `util/errors.h` into `common/messages.h` so there is a place for simple functions that generate user messages to live, and these functions are not part of the util library.
Motivation for this change is that the util library is a dependency of the kernel, and we should remove functionality from util that shouldn't be called by kernel code or kernel applications. These changes should also improve code organization and make functions easier to discover. Some of these same moves are (or were) part of #28690, but did not help with code organization, or made it worse, so it is better to move them and clean them up in the same PR so code only has to change one time.

This adds a bitset module that implements a BitSet<N> class, a variant
of std::bitset with a few additional features that cannot be implemented
in a wrapper without performance loss (specifically, finding first and
last bit set, or iterating over all set bits).
This is an STL-like container that interface-wise looks like std::deque, but
is backed by a (fixed size, with vector-like capacity/reserve) circular buffer.
Store the thread name in a `thread_local` variable of type `char[]`
instead of `std::string`. This avoids calling the destructor when
the thread exits. This is a workaround for
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=278701
For type-safety, return `std::string` from
`util::ThreadGetInternalName()` instead of `char[]`.
As a side effect of this change, we no longer store a reference
to a `thread_local` variable in `CLockLocation`. This was
dangerous because if the thread quits while the reference still
exists (in the global variable `lock_data`, see inside `GetLockData()`)
then the reference will become dangling.
There are no changes to behavior. Changes in this commit are all additions, and
are easiest to review using "git diff -U0 --word-diff-regex=." options.
Motivation for this change is to keep util functions with really generic names
like "Split" and "Join" out of the global namespace so it is easier to see
where these functions are defined, and so they don't interfere with function
overloading, especially since the util library is a dependency of the kernel
library and intended to be used with external code.
Move enum and message formatting functions to a common/messages header where
they should be more discoverable, and also out of the util library, so they
will not be a dependency of the kernel
The are no changes in behavior and no changes to the moved code.
Add separate PSBTError enum instead of reusing TransactionError enum for PSBT
operations, and drop unused error codes. The error codes returned by PSBT
operations and transaction broadcast functions mostly do not overlap, so using
an unified enum makes it harder to call any of these functions and know which
errors actually need to be handled.
Define PSBTError in the common library because PSBT functionality is
implemented in the common library and used by both the node (for rawtransaction
RPCs) and the wallet.
New node/types.h file is analagous to existing wallet/types.h and is a better
place to define simple node types that are shared externally with wallet and
gui code than the util library.
Motivation for this change is to completely remove util/error.h file currently
holding TransactionError in a followup commit.
Move miniscript / descriptor script parsing functions out of util library so
they are not a dependency of the kernel.
There are no changes to code or behavior.
This will help move the miniscript / descriptor parsing functions out of the
util library in an upcoming commit, so they are not exposed to libbitcoinkernel
applications. Moving the Split functions should also make them more
discoverable since they now close to related functions like Join.
The functions are moved verbatim without any changes.
Move HexStr and HexDigit functions from util to crypto. The crypto library does
not actually use these functions, but the consensus library does. The consensus
and util libraries not allowed to depend on each other, but are allowed to
depend on the cryto library, so the crypto library is a reasonable put these.
The consensus library uses HexStr and HexDigit in script.cpp, transaction.cpp,
and uint256.cpp.
The util library does not use HexStr but does use HexDigit in strencodings.cpp
to parse integers.
