It's very hard to randomly construct a transaction that would be the
parent of an existing orphanage tx. For functions like
AddChildrenToWorkSet and GetChildren that take orphan parents, use a tx
that was previously constructed.
Copying util::Result values is less efficient than moving them because they
allocate memory and contain strings. Also this is needed to avoid compile
errors in https://github.com/bitcoin/bitcoin/pull/25722 which adds a
std::unique_ptr member to util::Result which implicity disables copying.
fd81a37239 net: attempts to connect to all resolved addresses when connecting to a node (Sergi Delgado Segura)
Pull request description:
This is a follow-up of #28155 motivated by https://github.com/bitcoin/bitcoin/pull/28155#discussion_r1362677038
## Rationale
Prior to this, when establishing a network connection via `CConnman::ConnectNode`, if the connection needed address resolution, a single address would be picked at random from the resolved addresses and our node would try to connect to it. However, this would lead to the behavior of `ConnectNode` being unpredictable when the address was resolved to various ips (e.g. the address resolving to IPv4 and IPv6, but we only support one of them).
This patches the aforementioned behavior by going over all resolved IPs until a valid one is found or until we
exhaust them.

`util::Result` objects are aggregates that can hold multiple fields with
different information. Currently Result objects can only hold a success value
of an arbitrary type or a single bilingual_str error message. In followup PR
https://github.com/bitcoin/bitcoin/pull/25722, Result objects may be able to
hold both success and failure values of different types, plus error and warning
messages.
Having a Result::operator= assignment operator that completely erases all
existing Result information before assigning new information is potentially
dangerous in this case. For example, code that looks like it is assigning a
warning value could erase previously-assigned success or failure values.
Conversely, code that looks like it is just assigning a success or failure
value could erase previously assigned error and warning messages.
To prevent potential bugs like this, disable Result::operator= assignment
operator.
It is possible in the future we may want to re-enable operator= in limited
cases (such as when implicit conversions are not used) or add a Replace() or
Reset() method that mimicks default operator= behavior. Followup PR
https://github.com/bitcoin/bitcoin/pull/25722 also adds a Result::Update()
method providing another way to update an existing Result object.

65951e0418 index: race fix, lock cs_main while 'm_synced' is subject to change (Ryan Ofsky)
Pull request description:
Fixes#29831 and #29863. Thanks to Marko for the detailed description of the issue.
The race occurs because a block could be connected and its event signaled in-between reading the 'next block' and setting `m_synced` during the index initial synchronization. This is because `cs_main` is not locked through the process of determining the final index sync state.
To address the issue, the `m_synced` flag set has been moved under `cs_main` guard.

3e9c736a26 test: fix accurate multisig sigop count (BIP16), add unit test (Sebastian Falbesoner)
Pull request description:
In the course of reviewing #29589 I noticed the following buggy call-site of `CScriptOp.decode_op_n` in the CScript's `GetSigOpCount` method:
4cc99df44a/test/functional/test_framework/script.py (L591-L593)
This should be `lastOpcode` rather than `opcode`. The latter is either OP_CHECKMULTISIG or OP_CHECKMULTISIGVERIFY at this point, so `decode_op_n` would result in an error. Also, in `CScript.raw_iter`, we have to return the op as `CScriptOp` type instead of a bare integer, otherwise we can't call the decode method on it. To prevent this in the future, add some simple unit tests for `GetSigOpCount`.
Note that this was unnoticed, as the code part was never hit so far in the test framework.

c4f857cc30 test: Extends wait_for_getheaders so a specific block hash can be checked (Sergi Delgado Segura)
Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/18614
Previously, `wait_for_getheaders` would check whether a node had received **any** getheaders message. This implied that, if a test needed to check for a specific block hash within a headers message, it had to make sure that it was checking the desired message. This normally involved having to manually clear `last_message`. This method, apart from being too verbose, was error-prone, given an undesired `getheaders` would make tests pass.
This adds the ability to check for a specific block_hash within the last `getheaders` message.

Pull request description:
Fixes#29654 (as a side-effect)
Removing dependencies is a general goal of the project and the xz backdoor has been an additional wake up call recently. Libevent shows many of the same symptoms, few maintainers and slow releases. While libevent can not be removed completely over night we should start removing it’s usage where it's possible, ideally with the end goal to removing it completely.
This is a pretty easy win in that direction. The [`evhttp_uridecode` function from libevent](e0a4574ba2/http.c (L3542)) we were using in `urlDecode` could be easily emulated in fewer LOC. This also ports the [applicable test vectors over from libevent](https://github.com/libevent/libevent/blob/master/test/regress_http.c#L3430).

The previous behavior was the result of casting the result returned from the libevent function evhttp_uridecode to std:string but this was probably not intended.
The point of this was to be able to build bitcoin-tx and bitcoin-wallet without libevent, see #18504.
Now that we use our own implementation of urlDecode this is not needed anymore.

b22901dfa9 Avoid explicitly computing diagram; compare based on chunks (Pieter Wuille)
Pull request description:
This merges the `BuildDiagramFromChunks` and `CompareFeeRateDiagram` introduced in #29242 into a single `CompareChunks` function, which operates on sorted chunk data rather than diagrams, instead computing the diagram on the fly.
This avoids the need for the construction of an intermediary diagram object, and removes the slightly arbitrary "all diagrams must start at (0, 0)" requirement.
Not a big deal, but I think the result is a bit cleaner and not really more complicated.

Reorganize functional test framework unit tests to run in parallel
with other functional tests.
The option `skipunit` is removed, since unit tests no longer delay
functional test execution.
Unit tests are run by default when running all tests, and can be
run explicitly with `feature_framework_unit_tests.py` when running
a subset of tests.

dc55531087 wallet: compare address returned by displayaddress (Sjors Provoost)
6c1a2cc09a test: use h marker for external signer mock (Sjors Provoost)
Pull request description:
* HWI returns the requested address: as a sanity check, we now compare that to what we expected
* external signer documentation now reflects that HWI alternatives must implement this check
* both RPC and GUI will now return an error text, rather than just fail (the GUI even failed silently in some cases)

e30e8625bb test: remove duplicated ban test (brunoerg)
Pull request description:
Test the ban list is preserved through restart has been done by both `rpc_setban` and `p2p_disconnect_ban`. Since `p2p_disconnect_ban` does it in a more elegant way, we can keep only it and remove the other one.
