6888886cec Remove Chainstate::LoadMempool (MarcoFalke)
Pull request description:
Currently it is possible to import a mempool by placing it in the datadir and starting the node. However this has many issues:
* Users aren't expected to fiddle with the datadir, possibly corrupting it
* An existing mempool file in the datadir may be overwritten
* The node needs to be restarted
* Importing an untrusted file this way is dangerous, because it can corrupt the mempool
Fix all issues by adding a new RPC.

5364dd8666 test: locked_wallet, skip default fee estimation (furszy)
Pull request description:
Coming from https://github.com/bitcoin/bitcoin/pull/28139#discussion_r1284563239.
No test case in this file is meant to exercise fee estimation. All default wallets have a
custom tx fee set [here](b7138252ac/test/functional/wallet_fundrawtransaction.py (L100)). The only one missing is the one created for `locked_wallet`.

6a7686b446 scripted-diff: Specify Python major version explicitly on Windows (Hennadii Stepanov)
Pull request description:
On Windows, it is the accepted practice to use `py.exe` launcher:
- https://learn.microsoft.com/en-us/windows/python/faqs#what-is-py-exe-
- https://docs.python.org/3/using/windows.html#python-launcher-for-windows
One of its features is the correct handling of shebang lines like the one we use: `#!/usr/bin/env python3`.
However, Windows OS app execution aliases might [interfere](https://learn.microsoft.com/en-us/windows/python/faqs#why-does-running-python-exe-open-the-microsoft-store-) with the launcher's behaviour. Such aliases are enabled on Windows 11 by default:
![image](https://github.com/bitcoin/bitcoin/assets/32963518/407837ec-e89a-4bc1-98b1-db983002065a)
For example, on a fresh Windows 11 Pro installation with the Python installed from the [Chocolatey](https://community.chocolatey.org/packages/python/3.11.4) package manager, one will get the following error:

Pull request description:
Closes https://github.com/bitcoin/bitcoin/issues/27140
Adds test coverage for https://github.com/bitcoin/bitcoin/pull/20516 to ensure that https://github.com/bitcoin/bitcoin/issues/20511 is completed and may be closed.
This PR adds a test case to `feature_anchors.py` where an onion v3 address is set as a blocks-only relay peer and then shutdown, ensuring that the address is saved to anchors.dat in addrv2 format. We then ensure that bitcoin attempts to reconnect to that anchor address on restart.
To compute the addrv2 serialization of the onion v3 address, I added logic to `CAddress` in `messages.py`. This new logic is covered by extending `p2p_addrv2_relay.py` to include an onion v3 address. Future work will be adding coverage for ipv6, torv2 and cjdns in these modules and also `feature_proxy.py`
Also includes de/serialization unit test for `CAddress` in test framework.

2c0c6f4477 test: dedup file hashing using `sha256sum_file` helper (Sebastian Falbesoner)
Pull request description:
Rather than doing the open/read/hash-steps manually in the affected functional tests, we can just use the `sha256sum_file` helper from the utils module instead.
Note that for the tool_wallet.py test, the used hash is changed from sha1 to sha256, but as the only purpose is to detect file content changes, this doesn't matter. Also, the optimization using `memoryview` is overkill here, as the opened file has only a size of 24KiB and determining the hash via the helper doesn't take longer than a few hundred micro-seconds on my machine.

In the consistency check, it's not enough to check that our address/port is unique, only the combination of source and target must be unique. Otherwise, the OS may reuse ports for connections to different `-addrbind`, which was happening in the failed runs.
While at it, the second commit cleans up duplicate `getaddr` messages in `p2p_getaddr_caching.py` that do nothing but generate `Ignoring repeated "getaddr"` log messages (and cleans up some whitespace the python linter complains about).

c648bdbda2 test: create wallet specific for test_locked_wallet case (furszy)
Pull request description:
Coming from https://github.com/bitcoin/bitcoin/pull/28089#discussion_r1265478128.
Several test cases are relying on the node1 default wallet, which thanks to 'test_locked_wallet' is encrypted.
And can be only accessed within a specific timeframe (100ms), a duration internally set by the same test.
This situation introduces a potential race condition, where other tests must complete their operations within
the specified 100ms window to pass (otherwise the wallet gets re-locked and they fail).
This can be seen running the test in valgrind (https://github.com/bitcoin/bitcoin/pull/28089), where other test cases fail due the wallet re-locking
itself after the 100ms.

53c990ad34 test: fix `feature_addrman.py` on big-endian systems (Sebastian Falbesoner)
Pull request description:
The test `feature_addrman.py` currently serializes the addrdb without specifying endianness for `int`s, so the machine's native byte order is used (see https://docs.python.org/3/library/struct.html#byte-order-size-and-alignment) and the generated `peers.dat` would be invalid on big-endian systems (our internal (de)serializers always use little-endian, see `ser_{read,write}data32`). Fix this by explicitly specifying little-endian serialization via the `<` character in `struct.pack(...)`.
This is not detected by CI as we unfortunately don't run functional tests on big-endian systems there (I think we definitely should!).

Only the combined addr:port of source and destination
must be unique. If the destination is different, the same addr:port
for the source may be used by the OS.
* The node was only used to migrate the legacy txindex. But now that it
is known to be working and that 22.x is EOL, it can be dropped.
* Also, fix a typo to properly check the txindex of node [1], not [2].
Other tests are also relying on the node1 default wallet,

The test bumps the mocktime for ~2 weeks and then triggers eviction from the mempool. But this bump will also cause a new resubmit, and if the timing is such that this resubmit happens right after the eviction and before the check that the tx was evicted, the test can fail as in #28094:

cc781a2180 descriptor: InferScript, do not return top-level only func as sub descriptor (furszy)
286e0c7d5e wallet: loading, log descriptor parsing error details (furszy)
Pull request description:
Linked to #28057.
Currently, the `InferScript` function returns an invalid descriptor when it tries to infer a p2sh-p2pkh script whose pubkey is not known by the wallet.
This behavior occurs because the inference process bypasses the `pkh` subscript when the pubkey is not contained by the wallet (no pubkey provider), interpreting it as a `sh(addr(ADDR))` descriptor. Then, the failure arises because the `addr()` function is restricted to being used only at the top level.
For reviewers, would recommend to start by examining the functional test to understand the context and the circumstances on which this can result in a fatal error (e.g. during the migration process).

This PR adds missing test coverage for the `-blockmintxfee` option, which can be used by miners to specify the lowest fee-rate for transactions to be included in blocks. The setting was introduced in PR #9380 (commit daec955fd6), with the rationale to decouple different minimum fees from `-minrelaytxfee`. According to the PR description it _"should be set by miners to reflect their marginal cost of transmitting extra bytes."_.
On each iteration, the test creates and submits two txs using MiniWallet: one with the the minimum fee-rate as specified for `-blockmintxfee` and a second one with a fee-rate a little below that (-0.01 sats/vbyte). Then it checks that only the first one is picked for the block template and accordingly also only exists in the block that is mined after. This is repeatedly done for a fixed (but obviously somewhat arbitrary) list of different `-blockmintxfee` settings on a single node, including the default and zero (i.e. no minimum fee a.k.a. "include even zero-fee txs") settings.

e.g. sh(addr(ADDR)) or sh(raw(HEX)) are invalid descriptors.
Making sh and wsh top level functions to return addr/raw descriptors when
the subscript inference fails.

fa1471e575 refactor: Remove duplicate allNetMessageTypesVec (MarcoFalke)
Pull request description:
Now that `LIMIT_TO_MESSAGE_TYPE` is a runtime setting after commit 927b001502, it shouldn't hurt to also generate each message type individually. Something similar was done for the `rpc` target in commit cf4da5ec29.

7d83502d3d bumpfee: Allow original change position to be specified (Andrew Chow)
Pull request description:
When bumping the transaction fee, we will try to find the change output of the transaction in order to have an output whose value we can modify so that we can meet the target feerate. However we do not always find the change output which can cause us to unnecessarily add an additional output to the transaction. We can avoid this issue by outsourcing the determination of change to the user if they so desire.
This PR adds a `orig_change_pos` option to bumpfee which the user can use to specify the index of the change output.
