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.

Pull request description:
This is an attempt to #11775
This Pr will enable fee estimator to listen to ValidationInterface notifications to process new transactions added and removed from the mempool.
This PR includes the following changes:
- Added a new callback to the Validation Interface `MempoolTransactionsRemovedForConnectedBlock`, which notifies listeners about the transactions that have been removed due to a new block being connected, along with the height at which the transactions were removed.
- Modified the `TransactionAddedToMempool` callback parameter to include additional information about the transaction needed for fee estimation.
- Updated `CBlockPolicyEstimator` to process transactions using` CTransactionRef` instead of `CTxMempoolEntry.`
- Implemented the `CValidationInterface` interface in `CBlockPolicyEstimater` and overridden the `TransactionAddedToMempool`, `TransactionRemovedFromMempool`, and `MempoolTransactionsRemovedForConnectedBlock` methods to receive updates from their notifications.
Prior to this PR, the fee estimator updates from the mempool, i.e whenever a new block is connected all transactions in the block that are in our mempool are going to be removed using the `removeForBlock` function in `txmempool.cpp`.
This removal triggered updates to the fee estimator. As a result, the fee estimator would block mempool's `cs` until it finished updating every time a new block was connected.
Instead of being blocked only on mempool tx removal, we were blocking on both tx removal and fee estimator updating.
If we want to further improve fee estimation, or add heavy-calulation steps to it, it is currently not viable as we would be slowing down block relay in the process
This PR is smaller in terms of the changes made compared to #11775, as it focuses solely on enabling fee estimator updates from the validationInterface/cscheduler thread notifications.
I have not split the validation interface because, as I understand it, the rationale behind the split in #11775 was to have `MempoolInterface` signals come from the mempool and `CValidationInterface` events come from validation. I believe this separation can be achieved in a separate refactoring PR when the need arises.
Also left out some commits from #11775
- Some refactoring which are no longer needed.
- Handle reorgs much better in fee estimator.
- Track witness hash malleation in fee estimator
I believe they are a separate change that can come in a follow-up after this.

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.

Pull request description:
This PR is a tiny improvement for the `bip324_cipher_roundtrip` fuzz target: currently the damaging of input data for decryption (either ciphertext or aad) only ever happens in the lower nibble within the byte at the damage position, as the bit position for the `damage_val` byte was calculated with `damage_bit & 3` (corresponding to `% 4`) rather than `damage_bit & 7` (corresponding to the expected `% 8`).
Noticed while reviewing #28263 which uses similar constructs.

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.
Also, add missing includes to scriptpubkeyman.
Also, export dependecies of the BasicTestingSetup from setup_common.h,
to avoid having to include them when setup_common.h is already included.

Pull request description:
Generally, compile-time checks should be close to the code that use them. Especially, since `compat/assumptions.h` is only included in one place, where iwyu suggests to remove it.
Fix all issues:
* The `NDEBUG` check is used in `util/check`, so it is redundant in `compat/assumptions.h`.
* The `__cplusplus` check is redundant with `doc/dependencies.md` (see commit message).
* Add missing `// IWYU pragma: keep` to avoid removing the include by accident.

ACK 9e58c5bcd96e7ff2062274868814ccae0626589e. A sizeable diff, but very straightforward changes. Didn't see anything controversial. Left a few nits, but nothing blocking, only if you have to retouch.

5e7cc4144bb09cfde48ba5bc055a2da3ca4252d1 test: add unit test for CConnman::AddedNodesContain() (Jon Atack)
cc627169206fe902157806d88fcaf2b05701c38d p2p: do not make automatic outbound connections to addnode peers (Jon Atack)
Pull request description:
to allocate our limited outbound slots correctly, and to ensure addnode
connections benefit from their intended protections.
Our addnode logic usually connects the addnode peers before the automatic
outbound logic does, but not always, as a connection race can occur. If an
addnode peer disconnects us and if it was the only one from its network, there
can be a race between reconnecting to it with the addnode thread, and it being
picked as automatic network-specific outbound peer. Or our internet connection
or router or the addnode peer could be temporarily offline, and then return
online during the automatic outbound thread. Or we could add a new manual peer
using the addnode RPC at that time.
The race can be more apparent when our node doesn't know many peers, or with
networks like cjdns that currently have few bitcoin peers.
When an addnode peer is connected as an automatic outbound peer and is the only
connection we have to a network, it can be protected by our new outbound
eviction logic and persist in the "wrong role".
Finally, there does not seem to be a reason to make block-relay or short-lived
feeler connections to addnode peers, as the addnode logic will ensure we connect
to them if they are up, within the addnode connection limit.
Fix these issues by checking if the address is an addnode peer in our automatic
outbound connection logic.

007d6f0e85bc329040bb405ef6016339518caa66 test: fix `AddNode` unit test failure on OpenBSD (Sebastian Falbesoner)
Pull request description:
On OpenBSD 7.4, the following check of the unit test `test_addnode_getaddednodeinfo_and_connection_detection` currently fails:
```
BOOST_CHECK(!connman->AddNode({/*m_added_node=*/"127.1", /*m_use_v2transport=*/true}));
```
The reason for that is that this OS seemingly doesn't support the IPv4 shorthand notation with omitted zero-bytes:
```
$ ping 127.1
ping: no address associated with name
```
As a simple fix, this PR skips the check for this with a pre-processor #if. On NetBSD and FreeBSD, `127.1` is resolved correctly to localhost and hence the test passes (thanks to vasild for verifying on the latter!).
