380e365563 guix: switch to 6.1 kernel headers over 5.15 (fanquake)
Pull request description:
6.1 is the current longterm release: https://kernel.org/.
Note that using an older version of the kernel headers inside Guix, is not a "hack" for compatibility, and is explicitly recommended against by glibc:
https://sourceware.org/glibc/wiki/FAQ#What_version_of_the_Linux_kernel_headers_should_be_used.3F.
so using the latest version of the longterm headers seems appropriate.
The last time we changed this was when we consolidated all builds to 5.15, in #25006.

Allows calling UpdateLockPoints() with a (const) txiter. Note that this
was already possible for caller using mapTx.modify(txiter). The point
here is to not be accessing mapTx when doing so.
The behavior is the same as CalculateMemPoolAncestors. The only
difference is the string returned, and the string is discarded anyway
since checkChainLimits only cares about pass/fail.

This is deprecated on macOS:
```bash
ld: warning: -bind_at_load is deprecated on macOS
```
and likely redundant anyways, given the behaviour of dyld3.
Unfortunately libtool is still injecting a `-bind_at_load`:
```bash
# Don't allow lazy linking, it breaks C++ global constructors
# But is supposedly fixed on 10.4 or later (yay!).
if test CXX = "$tagname"; then
case ${MACOSX_DEPLOYMENT_TARGET-10.0} in
10.[0123])
func_append compile_command " $wl-bind_at_load"
func_append finalize_command " $wl-bind_at_load"
;;
esac
fi
```
so this doesn't remove all the warnings, but removes us as a potential
source of them.
Note that anywhere the ld64 warnings are being emitted, we are already
not adding this flag to our hardened ldflags, because of `-Wl,-fatal_warnings`.

5039c346ca init: completely remove `-zapwallettxes` (remaining hidden option) (Sebastian Falbesoner)
Pull request description:
The `-zapwallettxes` functionality has been removed in v0.21.0 (see commit 3340dbadd3 / PR #19671), with the parameter being kept as hidden option, to inform users via an exit error that `abandontransaction` should be used instead.
As any guides that still suggest to use `-zapwallettxes` would refer to a Bitcoin Core version that is EOL since many years (i.e. <= v0.20.x), it is highly unlikely that the error caused by the option is still relevant for any user, hence it seems fine to remove it now.

2574b7e177 net/rpc: Check all resolved addresses in ConnectNode rather than just one (Sergi Delgado Segura)
Pull request description:
## Rationale
Currently, `addnode` has a couple of corner cases that allow it to either connect to the same peer more than once, hence wasting outbound connection slots, or add redundant information to `m_added_nodes`, hence making Bitcoin iterate through useless data on a regular basis.
### Connecting to the same node more than once
In general, connecting to the same node more than once is something we should try to prevent. Currently, this is possible via `addnode` in two different ways:
1. Calling `addnode` more than once in a short time period, using two equivalent but distinct addresses
2. Calling `addnode add` using an IP, and `addnode onetry` after with an address that resolved to the same IP
For the former, the issue boils down to `CConnman::ThreadOpenAddedConnections` calling `CConnman::GetAddedNodeInfo` once, and iterating over the result to open connections (`CConman::OpenNetworkConnection`) on the same loop for all addresses.`CConnman::ConnectNode` only checks a single address, at random, when resolving from a hostname, and uses it to check whether we are already connected to it.
An example to test this would be calling:
```
bitcoin-cli addnode "127.0.0.1:port" add
bitcoin-cli addnode "localhost:port" add
```
And check how it allows us to perform both connections some times, and some times it fails.
The latter boils down to the same issue, but takes advantage of `onetry` bypassing the `CConnman::ThreadOpenAddedConnections` logic and calling `CConnman::OpenNetworkConnection` straightaway. A way to test this would be:
```
bitcoin-cli addnode "127.0.0.1:port" add
bitcoin-cli addnode "localhost:port" onetry
```
### Adding the same peer with two different, yet equivalent, addresses
The current implementation of `addnode` is pretty naive when checking what data is added to `m_added_nodes`. Given the collection stores strings, the checks at `CConnman::AddNode()` basically check wether the exact provided string is already in the collection. If so, the data is rejected, otherwise, it is accepted. However, ips can be formatted in several ways that would bypass those checks.
Two examples would be `127.0.0.1` being equal to `127.1` and `[::1]` being equal to `[0:0:0:0:0:0:0:1]`. Adding any pair of these will be allowed by the rpc command, and both will be reported as connected by `getaddednodeinfo`, given they map to the same `CService`.
This is less severe than the previous issue, since even tough both nodes are reported as connected by `getaddednodeinfo`, there is only a single connection to them (as properly reported by `getpeerinfo`). However, this adds redundant data to `m_added_nodes`, which is undesirable.
### Parametrize `CConnman::GetAddedNodeInfo`
Finally, this PR also parametrizes `CConnman::GetAddedNodeInfo` so it returns either all added nodes info, or only info about the nodes we are **not** connected to. This method is used both for `rpc`, in `getaddednodeinfo`, in which we are reporting all data to the user, so the former applies, and to check what nodes we are not connected to, in `CConnman::ThreadOpenAddedConnections`, in which we are currently returning more data than needed and then actively filtering using `CService.fConnected()`

Pull request description:
Split off from #26711 (suggested in https://github.com/bitcoin/bitcoin/pull/26711#issuecomment-1786392253). This is part of #27463.
- Add 2 new TxValidationResults
- `TX_RECONSIDERABLE` helps us encode transactions who have failed fee checks that can be bypassed using package validation. This is distinguished from `TX_MEMPOOL_POLICY` so that we re-validate a transaction if and only if it is eligible for package CPFP. In the future, we will have a separate cache for reconsiderable rejects so these transactions don't go in `m_recent_rejects`.
- `TX_UNKNOWN` helps us communicate that we aborted package validation and didn't finish looking at this transaction: it's not valid but it's also not invalid (i.e. don't cache it as a rejected tx)
- Return effective feerate and the wtxids of transactions used to calculate that effective feerate when the error is `TX_SINGLE_FAILURE`. Previously, we would only provide this information if the transaction passed. Now that we have package validation, it's much more helpful to the caller to know how the failing feerate was calculated. This can also be used to improve our submitpackage RPC result (which is currently a bit unhelpful when things fail).
- Use the newly added `CheckPackageMempoolAcceptResult` for existing package validation tests. This increases test coverage and helps test the changes made in this PR.

49d953281d fuzz: explicitly specify llvm-symbolizer path in runner (fanquake)
Pull request description:
It's not completely clear to me why this needs to be explicitly specified in some environments, and not in others, while at the same time that `llvm-symbolizer` is already in PATH, but this has fixed the 2 issues outlined in https://github.com/bitcoin/bitcoin/pull/28147.
Use `LLVM_SYMBOLIZER_PATH` as the env var, as that is somewhat also used inside LLVM, but not consistently, i.e it's checked for in the asan_symbolize script, but not in in the ubsan_symbolize script, or from in compiler-rt.

Pull request description:
This is joint work with amitiuttarwar.
This has the first few commits of #28463. It is not strictly a prerequisite for that, but has changes that in our opinion make sense on their own.
It improves the handling of maximum numbers for different connection types (that are set during init and don’t change after) by:
* moving all calculations into one place, `CConnMan::Init()`. Before, they were dispersed between `Init`, `CConnman::Init` and other parts of `CConnman`, resulting in some duplicated test code.
* removing the possibility of having a negative maximum of inbound connections, which is hard to argue about
* renaming of variables and doc improvements
