Pull request description:
It is impossible to run the miner without a node (validation, chainstate, mempool, rpc, ...). Also, the module is in the node library. Thus, it should be moved to `src/node`.
Also, replace the `validation.h` include in the header with a forward-declaration.

574cc4271a refactor: remove RecursiveMutex cs_totalBytesRecv, use std::atomic instead (Sebastian Falbesoner)
Pull request description:
This PR is related to #19303 and gets rid of the following RecursiveMutex members in class `CConnman`:
* for `cs_totalBytesRecv`, protecting `nTotalBytesRecv`, `std::atomic` is used instead (the member is only increment at one and read at another place, so this is sufficient)
* for `m_addr_fetches_mutex`, protecting `m_addr_fetches`, a regular `Mutex` is used instead (there is no chance that within one critical section, another one is called)
* for `cs_vAddedNodes`, protecting `vAddedNodes`, a regular `Mutex` is used instead (there is no chance that within one critical section, another one is called)
Additionally, the PR takes the chance to rename all node vector members (vNodes, vAddedNodes) and its corresponding mutexes (cs_vNodes, cs_vAddedNodes) to match the coding guidelines via a scripted-diff.

fa3e0da06b policy: Treat taproot as always active (MarcoFalke)
Pull request description:
Now that taproot is active, it can be treated as if it was always active for policy for the next major release. This simplifies the code and changes two things:
* Importing `tr` descriptors can be done before the chain is fully synced. This is fine, because the wallet will already generate `tr` descriptors by default (regardless of the taproot status) after commit 47fe7445e7.
* Valid taproot spends won't be rejected from the mempool before taproot is active. This is strictly speaking a bugfix after commit 47fe7445e7, since the wallet may generate taproot spends before the chain is fully synced. For example, a slow node or a purposefully offline node. Currently, the wallet needs the mempool to account for change. See https://github.com/bitcoin/bitcoin/issues/11887.
A similar change was done for segwit v0 in https://github.com/bitcoin/bitcoin/pull/13120 .
This effectively reverts commit c5ec0367d7.

Pull request description:
This should make it easier for the fuzz engine to explore multisig code
paths. See discussion in https://github.com/bitcoin/bitcoin/issues/23105
The downside is that all fuzz inputs that use ConsumeScript are now
invalidated and need to be re-generated.
Another downside may be that most multisig scripts from ConsumeScript are
using likely not fully valid pubkeys.

Blindly chose a cap of 10000 iterations for every loop, except for
the two in script_ops.cpp and scriptnum_ops.cpp which appeared to
(sometimes) be deserializing individual bytes; capped those to one
million to ensure that sometimes we try working with massive scripts.
There was also one fuzzer-controlled loop in timedata.cpp which was
already capped, so I left that alone.
git grep 'while (fuzz' should now run clean except for timedata.cpp
libsecp256k1's secp256k1_schnorrsig_sign only follows BIP340 exactly
if an aux_rand32 argument is passed. When no randomness is used
(as is the case in the current codebase here), there is no impact
on security between not providing aux_rand32 at all, or providing
an empty one. Yet, for repeatability/testability it is simpler
to always use an all-zero one.

Pull request description:
Similarly to how #18698 added `ProcessNewBlock()` and `ProcessNewBlockHeaders()` methods to the `ChainstateManager` class, this PR adds a new `ProcessTransaction()` method. Code outside validation no longer calls `AcceptToMemoryPool()` directly, but calls through the higher-level `ProcessTransaction()` method. Advantages:
- The interface is simplified. Calling code no longer needs to know about the active chainstate or mempool object, since `AcceptToMemoryPool()` can only ever be called for the active chainstate, and that chainstate knows which mempool it's using. We can also remove the `bypass_limits` argument, since that can only be used internally in validation.
- responsibility for calling `CTxMemPool::check()` is removed from the callers, and run automatically by `ChainstateManager` every time `ProcessTransaction()` is called.

Pull request description:
CJDNS overview
=====
CJDNS is like a distributed, shared VPN with multiple entry points where every participant can reach any other participant. All participants use addresses from the `fc00::/8` network (reserved IPv6 range). Installation and configuration is done outside of applications, similarly to VPN (either in the host/OS or on the network router).
Motivation
=====
Even without this PR it is possible to connect two Bitcoin Core nodes through CJDNS manually by using e.g. `-addnode` in environments where CJDNS is set up. However, this PR is necessary for address relay to work properly and automatic connections to be made to CJDNS peers. I.e. to make CJDNS a first class citizen network like IPv4, IPv6, Tor and I2P.
Considerations
=====
An address from the `fc00::/8` network, could mean two things:
1. Part of a local network, as defined in RFC 4193. Like `10.0.0.0/8`. Bitcoin Core could be running on a machine with such address and have peers with those (e.g. in a local network), but those addresses are not relayed to other peers because they are not globally routable on the internet.
2. Part of the CJDNS network. This is like Tor or I2P - if we have connectivity to that network then we could reach such peers and we do relay them to other peers.
So, Bitcoin Core needs to be able to tell which one is it when it encounters a bare `fc00::/8` address, e.g. from `-externalip=` or by looking up the machine's own addresses. Thus a new config option is introduced `-cjdnsreacable`:
* `-cjdnsreacable=0`: it is assumed a `fc00::/8` address is a private IPv6 (1.)
* `-cjdnsreacable=1`: it is assumed a `fc00::/8` address is a CJDNS one (2.)
After setting up CJDNS outside of Bitcoin Core, a node operator only needs to enable this option.
Addresses from P2P relay/gossip don't need that because they are properly tagged as IPv6 or as CJDNS.
For testing

Makes the test more minimal. We're just trying to test that our package
sanitization logic is correct. Now that this code lives in its own
function (rather than inside of AcceptMultipleTransactions), there's no
need to call ProcessNewPackage to test this.
The tests `streams_tests/streams_buffered_file` and `streams_tests/streams_buffered_file_rand`
did not use a the temporary directory provided by `BasicTestingSetup`, so it was not possible
to execute multiple of them in parallel. This fixes that.
To reproduce, run
```sh
parallel --halt now,fail=1 './src/test/test_bitcoin --run_test=streams_tests/streams_buffered_file_rand' -- ::: {1..1000}
```
This executes the test 1000 times, one job per CPU. It works on that commit but mergebase fails quickly.
80dc829be7 tests: Calculate fees more similarly to CFeeRate::GetFee (Andrew Chow)
ce2cc44afd tests: Test for assertion when feerate is rounded down (Andrew Chow)
0fbaef9676 fees: Always round up fee calculated from a feerate (Andrew Chow)
Pull request description:
When calculating the fee for a feerate, it is possible that the final calculation will have fractional satoshis. Currently those are ignored via truncation which results in the absolute fee being rounded down. Rounding down is problematic because it results in a feerate that is slightly lower than the feerate represented by the `CFeeRate` object. A slightly lower feerate particularly causes issues for coin selection as it can trigger an assertion error. To avoid potentially underpaying the feerate (and the assertion), always round up the calculated fee.
A test is added for the assertion, along with a comment explaining what happens.
It is unlikely that a user can trigger this as it requires a very specific set of rounding errors to occur as well as the transaction not needing any change and being right on the lower bound of the exact match window. However I was able to trigger the assertion while running coin selection simulations, albeit after thousands of transactions and with some weird feerates.

AcceptToMemoryPool() is called for an invalid coinbase transaction, so
setting bypass_limits to true or false has no impact on the test.
The only way that changing bypass_limits from true to false could change
the result would be to change the outcome to INVALID(TX_MEMPOOL_POLICY).
Since the ATMP call in this test results in INVALID(TX_CONSENSUS) both
before and after this change, there is no change in behavior.
AcceptToMemoryPool() is called for transactions with fees above
minRelayTxFee and with the mempool not full, so setting bypass_limits to
true or false has no impact on the test.
The only way that changing bypass_limits from true to false could change
the result would be to change the outcome to INVALID(TX_MEMPOOL_POLICY).
Since all the ATMP calls in this test result in VALID both before and
after this change, there is no change in behavior.
6ae9f1cf96 Disable lock contention logging in checkqueue_tests (Jon Atack)
Pull request description:
This patch disables lock contention logging in the checkqueue_tests as some of these tests are designed to be heavily contested to trigger race conditions or other issues. This created very large log files when run with DEBUG_LOCKCONTENTION defined (up to v22) or with lock logging enabled by default in current master.
Examples running the following command:
```
$ ./src/test/test_bitcoin -t checkqueue_tests/test_CheckQueue_Correct_Random -- DEBUG_LOG_OUT > testlog.txt
