60ca5d5508 test: p2p: add test for rejected tx request logic (`m_recent_rejects` filter) (Sebastian Falbesoner)
e9dc511a7e fixup: get all utxos up front in fill_mempool, discourage wallet mixing (glozow)
Pull request description:
Motivated by the discussion in #28970 (https://github.com/bitcoin/bitcoin/pull/28970#discussion_r1553911167), this PR adds test coverage for the logic around the `m_recent_rejects` filter, in particular that the filter is cleared after a new block comes in:
f0794cbd40/src/net_processing.cpp (L2199-L2206)
As expected, the second part of the test fails if the following patch is applied:
```diff
diff --git a/src/net_processing.cpp b/src/net_processing.cpp
index 6996af38cb..5cb1090e70 100644

- m_recent_rejects.reset();

}

```
I'm still not sure in which file this test fits best, and if there is already test coverage for the first part of the test somewhere. Happy for any suggestions.

c6d1b8de89 gui: change example address from legacy (P2PKH) to bech32m (P2TR) (Sebastian Falbesoner)
Pull request description:
Legacy addresses are less and less common these days and not recommended to use, so it seems senseful to also reflect that in the example addresses and update to the most recent address / output type (bech32m / P2TR). Also, as I couldn't see any value in computing these at runtime, they are pre-generated. This was done with the following Python script, executed in `./test/functional` (it's also included in the commit body, though without the she-bang):
```python
#!/usr/bin/env python3
from test_framework.segwit_addr import CHARSET, decode_segwit_address, encode_segwit_address
from test_framework.messages import sha256
output_key = sha256(b'bitcoin dummy taproot output key')
for network, hrp in [('mainnet', 'bc'), ('signet', 'tb'), ('testnet', 'tb'), ('regtest', 'bcrt')]:
dummy_address = encode_segwit_address(hrp, 1, output_key)
while decode_segwit_address(hrp, dummy_address) != (None, None):
last_char = CHARSET[(CHARSET.index(dummy_address[-1]) + 1) % 32]
dummy_address = dummy_address[:-1] + last_char
print(f'{network:7} example address: {dummy_address}')
```
Note that the last bech32 character is modified in order to make the checksum fail.

0244416aac security: restrict abis in bitcoind.service (Charlie)
Pull request description:
[As noted here](https://www.freedesktop.org/software/systemd/man/systemd.exec.html#MemoryDenyWriteExecute=), it's a good idea to pair `MemoryDenyWriteExecute=true` with `SystemCallArchitectures=native` because `MemoryDenyWriteExecute` can be circumvented in some operating systems which support multiple ABIs like x86/x86-64.
This helps restrict the possible application binary interfaces (ABIs) that can be used when running bitcoind through systemd, reducing the attack surface area.

1ae5b208d3 test: fix intermittent failure in p2p_compactblocks_hb.py (Martin Zumsande)
Pull request description:
Fixes#29860
As a result of node1 receiving a block, it sends out SENDCMPCT messages to some of its peers to update the high-bandwidth status. We need to wait until those are received and processed by the peers to avoid intermittent failures. Before, we'd only wait until all peers have synced with the new block (within `generate`) which is not sufficient.
I could reproduce the failure by adding a `std::this_thread::sleep_for(std::chrono::milliseconds(1000));` sleep to the [net_processing code](c7567d9223/src/net_processing.cpp (L3763)) that processes `NetMsgType::SENDCMPCT`.

b7ba60f81a test: add coverage for -reindex and assumeutxo (Martin Zumsande)
e57f951805 init, validation: Fix -reindex option with an existing snapshot (Martin Zumsande)
Pull request description:
In c711ca186f logic was introduced that `-reindex` and `-reindex-chainstate` will delete the snapshot chainstate.
This doesn't work currently, instead of deleting the snapshot chainstate the node crashes with an assert (this can be triggered by applying the added test commit on master).
Fix this, and another bug that would prevent the new active chainstate from having a mempool after `-reindex` has deleted the snapshot (also covered by the test).

Bug introduced by https://github.com/bitcoin/bitcoin/pull/28950 , and I discovered it rebasing https://github.com/bitcoin/bitcoin/pull/28984 since it's easier to hit in that test scenario.
Tests in place were only checking `AcceptSingleTransaction`-level checks due to package evaluation only triggering when minfee is too high for the parent transaction.
Added test along with fix, moving the fill_mempool utility into a common area for re-use.

95c594f4e9 depends: remove no longer needed patch for Boost::Process (Sebastian Falbesoner)
Pull request description:
As Boost::Process has been replaced by cpp-subprocess (PR #28981), this patch touches an unused code part and is hence not needed anymore.

cc8b9875b1 Add `cpp-subprocess` header-only library (Hennadii Stepanov)
Pull request description:
Closes https://github.com/bitcoin/bitcoin/issues/24907.
This PR is based on **theStack**'s [work](https://github.com/bitcoin/bitcoin/issues/24907#issuecomment-1466087049).
The `subprocess.hpp` header has been sourced from the [upstream repo](https://github.com/arun11299/cpp-subprocess) with the only modification being the removal of convenience functions, which are not utilized in our codebase.
Windows-related changes will be addressed in subsequent follow-ups.

a8203e9412 refactor: Simplify `extra_txn` to be a vec of CTransactionRef instead of a vec of pair<Wtxid, CTransactionRef> (AngusP)
c3c18433ae refactor: Use typesafe Wtxid in compact block encoding message, instead of ambiguous uint256. (AngusP)
Pull request description:
The first commit replaces `uint256` with typesafe `Wtxid` (or `Txid`) types introduced in #28107.
The second commit then simplifies the extra tx `vector` to just be of `CTransactionRef`s instead of a `std::pair<Wtxid, CTransactionRef>`, as it's easy to get a `Wtxid` from a transaction ref.
