Pull request description:
Increases the encapsulation/modularity of the versionbits code, moving more of the logic into the versionbits module rather than having it scattered across validation and rpc code. Updates unit/fuzz tests to test the actual code used rather than just a close approximation of it.

Pull request description:
The assumeutxo data for the fuzz target could change and invalidate the hash silently, preventing the fuzz target from reaching some code paths. Fix this by introducing a unit test which would break if the snapshot data the fuzz target relies on were to change.
In implementing this i noticed the height used for coins in the fuzz target is actually off-by-one (as if the first block in the created chain was the genesis but it's block `1`), so fix that too.

This commit is done in preparation for the next commit. Here, the block
tree options are moved to the blockmanager options and the block tree is
instantiated through a helper method of the BlockManager, which is
removed again in the next commit.

Rather than having the rule change period/threshold be constant for all
potential deployments on a chain, have it be specific to the deployment
itself. This both matches history (BIP 9 specified a 2016 block period
and 1916 block threshold; BIP 91 specified a 336 block period and 269
block threshold; and BIP 341 specified a 2016 block period and 1815
block threshold), and allows the code to be simplified, as only the
BIP9Deployment structure is needed, not the full Consensus::Params
structure.

Pull request description:
Carrying non-kernel related fields in the cache sizes for the indexes is confusing for kernel library users. The cache sizes are set currently with magic numbers in bitcoin-chainstate. The comments for the cache size calculations are not completely clear. The constants for the cache sizes are also currently in `txdb.h`, which is not an ideal place for holding all cache size related constants.
Solve these things by moving the kernel-specific cache size fields to their own struct and moving the constants to either the node or the kernel cache sizes.
This slightly changes the way the cache is allocated if (and only if) the txindex and/or blockfilterindex is used. Since they are now given precedence over the block tree db cache, this results in a bit less cache being allocated to the block tree db, coinsdb and coins caches. The effect is negligible though, i.e. cache sizes with default dbcache reported through the logs are:
master:
```

* Using 2.0 MiB for block index database
* Using 56.0 MiB for transaction index database

This avoids having to rely on implicit casts when passing them to the
various functions allocating the caches.
This also ensures that if the requested amount of db_cache does not fit
in a size_t, it is clamped to the maximum value of a size_t.
Also take this opportunity to make the total amounts of cache in the
chainstate manager a size_t too.
They are not related to the txdb, so a better place for them is the
new kernel and node cache file. Re-use the default amount of kernel
cache for the default node cache.

We try to ensure that dust is spent in blocks by requiring:
- ephemeral dust tx is 0-fee
- ephemeral dust tx only has one dust output
- If the ephemeral dust transaction has a child,
the dust is spent by by that child.
0-fee requirement means there is no incentive to mine
a transaction which doesn't have a child bringing its
own fees for the transaction package.

Given https://github.com/bitcoin/bitcoin/pull/30493 and the related discussion on network uptake it's probably not helpful to have an option for a feature that will not be respected by the network in any meaningful way.
Wallet changes can be done in another PR on its own cadence to account for possible fingerprinting, waiting for fullrbf logic to permeate the network, etc.

The added regtest option -test=bip94 is only used in the functional
test for BIP94.
This is done because the default regtest consensus rules
should aim to follow to mainnet, not testnet.

Pull request description:
Split out of https://github.com/bitcoin/bitcoin/pull/30377#discussion_r1722326803.
Replace `_hex_v_u8` for `CScript` appends to `_hex`, to skip vector conversion before serializing to the `prevector` in `CScript`.
To enable both `unsigned char` and `std::byte` values, I've extracted the existing serialization to append the size & data in separate private methods to clarify that it does more than just a simple data insertion.
There were also discussion on eliminating the operators here completely to obviate when we're serializing fixed-size collections as raw bytes, and when we're prefixing them with their size - should also be done in a separate PR.

Pull request description:
Since the move to cmake, the kernel static library that is installed after a cmake --install build is unusable. It lacks symbols for the internal libraries, besides those defined in the kernel library target.
Fix this by explicitly installing all the required internal static libraries. To make usage of these installed libraries easy, add a pkg-config file that can be used during linking.
This patch can be tested with:
```
cmake -B build -DBUILD_SHARED_LIBS=OFF -DBUILD_KERNEL_LIB=ON
cmake --build build
cmake --install build
g++ -std=c++20 -o test_chainstate src/bitcoin-chainstate.cpp -I/home/drgrid/bitcoin/src $(pkg-config --libs --static libbitcoinkernel)

Since the move to cmake, the kernel static library that is installed
after a cmake --install build is unusable. It lacks symbols for the
internal libraries, besides those defined in the kernel library target.
This is because cmake, unlike the libtool archiver, does not combine
multiple static libraries into a single static library on installation.
This is likely an intentional design choice, since there were a bunch of
caveats to the way libtool calculated these libraries.
Fix this problem by installing all the required libraries. The user must
then link all of them along with the bitcoin kernel library.
This change enables building and installing only `libbitcoinkernel`,
without the need to disable other targets during the project build
system generation.
The following scripted-diff commit will replace ParseHex("...") with "..."_hex_u8, but this replacement will not work in cases where vectors are needed instead of arrays, and is not ideal in cases where std::byte is accepted.
For example, it is currently necessary to use _hex_v_u8 when calling CScript operator<< because that operator does not currently support std::array or std::byte.
Conversely, it is incorrect to use _hex_v instead of _hex in net_processing.cpp for the MakeAndPushMessage argument, because if the argument is a std::vector it is considered variable-length and serialized with a size prefix, but if the argument is a std::array or Span is it considered fixed length and serialized without a prefix.
By the same logic, it is also safe to change the NUMS_H constant in pubkey.cpp from a std::vector to std::array because it is never serialized.

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.

fadf0a7e15d66ba3230153e789b785e6cf8ab84c refactor: Remove Span operator==, Use std::ranges::equal (MarcoFalke)
Pull request description:
`std::span` removed the comparison operators, so it makes sense to remove them for the `Span` "backport" as well. Using `std::ranges::equal` also has the benefit that some `Span` temporary constructions can now be dropped.
This is required to move from `Span` toward `std::span`.

49f9b645ea3f42c1b9e0a83b26af8fc8f6fa159d refactor: Testnet4 - Replace uint256S("str") -> uint256{"str"} (Hodlinator)
Pull request description:
Ran scripted-diff from 2d9d752e4fc30aabf2ddd36ca7a63432d26d4fea:
```
sed -i --regexp-extended -e 's/\buint256S\("(0x)?([^"]{64})"\)/uint256{"\2"}/g' $(git grep -l uint256S)
```
Follow-up to Testnet4 introduction #29775 which overlapped with work on `uint256` `consteval` ctor #30560 (the latter includes the scripted-diff commit).
Going forward `uint256{}` should be used for constants instead of `uint256S()`.

Ran scripted-diff from 2d9d752e4fc30aabf2ddd36ca7a63432d26d4fea.
Follow-up to #29775 which overlapped with work on #30560 (the latter includes the scripted-diff commit).
This currently has no effect due to fPowNoRetargeting,
except for the getnetworkhashps when called with -1.
It will when the next commit enforces the timewarp attack mitigation on regtest.
