3ba815b42db74804e341ce15f648c2b297af55ca Make v2transport default for addnode RPC when enabled (Pieter Wuille)
Pull request description:
Since #29058, several types of manually configured connections will attempt v2 connections when `-v2transport` is enabled, except for the `addnode` RPC, as that one has an explicit argument to enable or disable.
Make the default for that RPC match the `-v2transport` setting so the behavior matches that of other manual connections from a user perspective.

c3d02be536ac3f35c10efa03653186a17ebbfc12 [test] rescan legacy wallet with reorged parent + IsFromMe child in mempool (Gloria Zhao)
Pull request description:
Originally motivated by #29019, which reverts back to having `requestMempoolTransactions` emit `transactionAddedToMempool` in `mapTx` default order instead of `GetSortedDepthAndScore` order.
It's important that these notifications happen in topological order, otherwise the wallet rescan may miss transactions that belong to it. Notably, checking whether a transaction `IsFromMe` requires knowing its inputs, which may be from a mempool parent.
When using `mapTx` order, a parent may come later than its child if it was added from a block disconnected in a reorg.
This PR adds a test for this case.

Test that wallet rescans process transactions topologically, even if a
parent's entry into the mempool is later than that of its child.
This behavior is important because IsFromMe requires the ability to look
up a transaction's inputs.

- changed `prioritisation-map` in the `RPCResult` to `""`
- Directly constructing 2 entry map for getprioritisedtransactions in functional tests
- renamed `txid` to `transactionid` in `RPCResult` to be more consistent with naming elsewhere
- exposed the `modified_fee` field instead of having it be a useless arg

Pull request description:
There are at least three ways to detect the operating system in Python3:
- `os.name` (https://docs.python.org/3.9/library/os.html#os.name)
- `sys.platform` (https://docs.python.org/3.9/library/sys.html#sys.platform)
- `platform.system()` (https://docs.python.org/3.9/library/platform.html#platform.system)
We are currently using all of them in functional tests (both in individual tests and shared test framework code), which seems a bit messy. This PR consolidates into using `platform.system()`, as it appears to be one most consistent and easy to read (see also [IRC discussion](https://bitcoin-irc.chaincode.com/bitcoin-core-dev/2023-12-08#989301;) and table below). `sys.platform` is inconsistent as it has the major version number encoded for BSD systems, which doesn't make much sense for e.g. OpenBSD, where there is no concept of major versions, but instead the version is simply increased by 0.1 on each release.
Note that `os.name` is still useful to detect whether we are running a POSIX system (see `BitcoinTestFramework.skip_if_platform_not_posix`), so for this use-case it is kept as only exception. The following table shows values for common operating systems, found via
```
$ python3 -c "import os; import sys; import platform; print(os.name, sys.platform, platform.system())"
```
| OS | os.name | sys.platform | platform.system() |
|--------------|---------|--------------|--------------------|
| Linux 6.2.0 | posix | linux | Linux |
| MacOS* | posix | darwin | Darwin |
| OpenBSD 7.4 | posix | openbsd7 | OpenBSD |
| Windows* | nt | win32 | Windows |
\* = I neither have a MacOS nor a Windows machine available, so I extracted the values from documentation and our current code. Also I'm relying on CI for testing the relevant code-paths. Having reviewers to this this locally would be very appreciated, if this gets Concept ACKed.

Pull request description:
Not all of the data in an address book entry was being copied to the watchonly and solvables wallets. This includes information such as whether the address was previously spent, and any receive requests that may exist. A test has been added to check that the previously spent information is copied, although it passes without the changes in this PR since this information is also regenerated when a transaction is loaded/added into a wallet.

fa46cc22bc696e6845915ae91d6b68e36bf4c242 Remove deprecated -rpcserialversion (MarcoFalke)
Pull request description:
The flag is problematic for many reasons:
* It is deprecated
* It is a global flag, requiring a restart to change, as opposed to a flag that can be set on each RPC invocation
* It may be hidden in config files by accident, hard to debug, causing LND crashes and bugs, see https://github.com/bitcoin/bitcoin/issues/28730#issuecomment-1780940868
* It makes performance improvements harder to implement: https://github.com/bitcoin/bitcoin/pull/17529#issuecomment-556082818
Fix all issues by removing it.
If there is a use-case, likely a per-RPC flag can be added, if needed.

Fixing #28897.
As the user may have imported a descriptor with a timestamp newer
than the actual birth time of the first key (by setting 'timestamp=now'),
the wallet needs to update the birth time when it detects a transaction
older than the oldest descriptor timestamp.

Solve this by using the recently introduced `wait_for_new_peer` helper (see #29006, commit 00e0658e77f66103ebdeb29def99dc9f937c049d), which is more robust.

00e0658e77f66103ebdeb29def99dc9f937c049d test: fix v2 transport intermittent test failure (#29002) (Sebastian Falbesoner)
Pull request description:
This PR improves the following fragile construct for detection of a new connection to the node under test in `p2p_v2_transport.py`:
6d5790956f/test/functional/p2p_v2_transport.py (L154-L156)
Only relying on the number of peers for that suffers from race conditions, as unrelated previous peers could disconnect at anytime in-between. In the test run in #29002, the following happens:
- `getpeerinfo()` is called the first time -> assigned to `num_peers`
- **previous peer disconnects**, the node's peer count is now `num_peers - 1` (in most test runs, this happens before the first getpeerinfo call)
- new peer connects, the node's peer count is now `num_peers`
- the condition that the node's peer count is `num_peers + 1` is never true, test fails
Use the more robust approach of watching for an increased highest peer id instead (again using the `getpeerinfo` RPC call), with a newly introduced context manager method `TestNode.wait_for_new_peer()`. Note that for the opposite case of a disconnect, no new method is introduced; this is currently used only once in the test and is also simpler.
Still happy to take suggestions for alternative solutions.
Fixes#29002.

Verifying the wallet updates the birth time accordingly when it
detects a transaction with a time older than the oldest descriptor
timestamp.
This could happen when the user blindly imports a descriptor with
'timestamp=now'.
Previously, starting a second bitcoind using the same datadir would
correctly fail to init and shutdown. However during shutdown the PID
file belonging to the first instance would be erroneously removed by
the second process shutting down.
Fix this to only delete the PID file if we created it.

b67db52c399089e5d4c4202ebb905794dfd050d0 RPC submitpackage: change return format to allow partial errors (Greg Sanders)
Pull request description:
This was prompted by errors being returned that didn't "make any sense" to me, because it would for example return a "fee too low" error, when the "real" error was the child had something invalid, which disallowed CPFP evaluation. Rather than make judgment calls on what error is important(which is currently just return the "first"!), we simply return all errors and let the callers determine what's best.
Added a top level `package_msg` for quick eye-balling of general success of the package.
This PR also fixes a couple bugs:
1) Currently we don't actually broadcast a transaction, even if it was entered into our mempool, if a subsequent transaction causes `PKG_TX` failure.
2) "other-wtxid" is uncovered by tests, but IIUC was previously required to return "fees" and "vsize" results, but did not. I just make those results optional.

Behavior prior to this commit allows some transactions to
enter into the local mempool but not be reported to the user
when encountering a PackageValidationResult::PCKG_TX result.
This is further compounded with the fact that any transactions
submitted to the mempool during this call would also not be
relayed to peers, resulting in unexpected behavior.
Fix this by, if encountering a package error, reporting all
wtxids, along with a new error field, and broadcasting every
transaction that was found in the mempool after submission.
Note that this also changes fees and vsize to optional,
which should also remove an issue with other-wtxid cases.

Pull request description:
When writing some scripts that iterated over many blocks to generate hashrate estimates I realized that my script was going out of range of the current chain tip height but was not encountering any errors.
I believe that passing an invalid block height to this function but receiving the hashrate estimate for the chain tip instead should be considered unexpected behavior.

Pull request description:
This makes the functional test suite compatible with BIP324, so that
`python3 test_runner.py --v2transport`
should succeed (currently, 12 tests fail for me on master).
Includes two commits by TheStack I found in an old discussion https://github.com/bitcoin/bitcoin/pull/28331#discussion_r1326714164
Note that even though all tests should pass, the python `p2p.py` module will do v2 connections only after the merge of #24748, so that for now only connections between two full nodes will actually run v2.
Some of the fixed tests were added with `--v2transport` to the test runner. Though after #24748 we might also want to consider running the entire suite with `--v2transport` in some CI.
