Pull request description:
This is part of #27463. It splits off the more trivial changes from #26711 for ease of review, as requested in https://github.com/bitcoin/bitcoin/pull/26711#issuecomment-1786392253.
- Split package sanitization in policy/packages.h into helper functions
- Add some tests for its quirks (https://github.com/bitcoin/bitcoin/pull/26711#discussion_r1340521597)
- Rename `CheckPackage` to `IsPackageWellFormed`
- Improve the `CreateValidTransaction` unit test utility to:
- Configure the target feerate and return the fee paid
- Signal BIP125 on transactions to enable RBF tests
- Allow the specification of multiple inputs and outputs
- Move `CleanupTemporaryCoins` into its own function to be reused later without duplication

Pull request description:
This PR is a follow-up to fix review comments and a bugfix from #28385
The PR
- Updated `DisconnectedBlockTransactions`'s `MAX_DISCONNECTED_TX_POOL` from kb to bytes.
- Moved `DisconnectedBlockTransactions` implementation code to `kernel/disconnected_transactions.cpp`.
- `AddTransactionsFromBlock` now assume duplicate transactions are not passed by asserting after inserting each transaction to `iters_by_txid`.
- Included a Bug fix: In the current master we are underestimating the memory usage of `DisconnectedBlockTransactions`.
* When adding and subtracting `cachedInnerUsage` we call `RecursiveDynamicUsage` with `CTransaction` which invokes this [`RecursiveDynamicUsage(const CTransaction& tx)`](6e721c923c/src/core_memusage.h (L32)) version of `RecursiveDynamicUsage`, the output of that call only account for the memory usage of the inputs and outputs of the `CTransaction`, this omits the memory usage of the `CTransaction` object and the control block.
* This PR fixes this bug by calling `RecursiveDynamicUsage` with `CTransactionRef` when adding and subtracting `cachedInnerUsage` which invokes [`RecursiveDynamicUsage(const std::shared_ptr<X>& p)`](6e721c923c/src/core_memusage.h (L67)) version of `RecursiveDynamicUsage` the output of the calculation accounts for the` CTransaction` object, the control blocks, inputs and outputs memory usage.
* see [comment ](https://github.com/bitcoin/bitcoin/pull/28385#discussion_r1322948452)
- Added test for DisconnectedBlockTransactions memory limit.

Pull request description:
We currently have two different identifiers for transactions: `txid` (refering to the hash of a transaction without witness data) and `wtxid` (referring to the hash of a transaction including witness data). Both are typed as `uint256` which could lead to type-safety bugs in which one transaction identifier type is passed where the other would be expected.
This PR introduces explicit `Txid` and `Wtxid` types that (if used) would cause compilation errors for such type confusion bugs.
(Only the orphanage is converted to use these types in this PR)

ec84f999f1408b7f1ff4498f78c33b34c30e934c log: Don't log cache rebalancing in absense of a snapshot chainstate (Fabian Jahr)
Pull request description:
I have noticed that this log now is always printed, even if there is no snapshot chainstate present or even was present. I think this is confusing to users that have never even thought about using assumeutxo since in that case the rebalancing is just ensuring the normal environment with one chainstate. So I suggest we don't log in absence of a snapshot chainstate. We could also think about rewording the message instead but I think this is simpler.

Permit (restricted topology) submitpackage RPC outside of regtest. Suggested in https://github.com/bitcoin/bitcoin/pull/26933#issuecomment-1510851570
This RPC should be safe but still experimental - interface may change, not all features (e.g. package RBF) are implemented, etc. If a miner wants to expose this to people, they can effectively use "package relay" before the p2p changes are implemented. However, please note **this is not package relay**; transactions submitted this way will not relay to other nodes if the feerates are below their mempool min fee. Users should put this behind some kind of rate limit or permissions.

This ensures that we avoid any unexpected conditions inherent in
transferring non-empty mempools across chainstates.
Note that this should never happen in practice given that snapshot
activation will not occur outside of IBD, based upon the height checks
in `loadtxoutset`.
When using an assumedvalid (snapshot) chainstate along with a background
chainstate, we are syncing two very different regions of the chain
simultaneously. If we use the same blockfile space for both of these
syncs, wildly different height blocks will be stored alongside one
another, making pruning ineffective.
This change implements a separate blockfile cursor for the assumedvalid
chainstate when one is in use.
Use the expected AssumeutxoData in order to bootstrap nChainTx values
for assumedvalid blockindex entries in the snapshot chainstate. This
is necessary because nChainTx is normally built up from nTx values,
which are populated using blockdata which the snapshot chainstate
does not yet have.
In future commits, loading the block index while making use of a
snapshot is contingent on the snapshot being recognized by chainparams.
Ensure all existing unittests that use snapshots use a recognized
snapshot (at height 110).

Introduces ChainstateManager::GetPruneRange().
The prune budget is split evenly between the number of chainstates,
however the prune budget may be exceeded if the resulting shares are
beneath `MIN_DISK_SPACE_FOR_BLOCK_FILES`.
When using an assumedvalid chainstate, only process validationinterface
callbacks from the background chainstate within indexes. This ensures
that all indexes are built in-order.
Later, we can possibly designate indexes which can be built out of order
and continue their operation during snapshot use.
Once the background sync has completed, restart the indexes so that
they continue to index the now-validated snapshot chainstate.
This allows us to reference assumeutxo configuration by blockhash as
well as height; this is helpful in future changes when we want to
reference assumeutxo configurations before the block index is loaded.
Add new PeerManagerImpl::TryDownloadingHistoricalBlocks method and use it to
request background chain blocks in addition to blocks normally requested by
FindNextBlocksToDownload.

5671c15f4520c6dc20e0805fd0b06157ff94bcd7 blockstorage: Mark FindBlockPos as nodiscard (TheCharlatan)
Pull request description:
The goal of this PR is to establish that fatal blockstorage flush errors should be treated as errors at their call site.
Prior to this patch `FlushBlockFile` may have failed without returning in `Chainstate::FlushStateToDisk`, leading to a potential write from `WriteBlockIndexDB` that may refer to a block that is not fully flushed to disk yet. By returning if either `FlushUndoFile` or `FlushBlockFile` fail, we ensure that no further write operations take place that may lead to an inconsistent database when crashing. Add `[[nodiscard]]` annotations to them such that they are not ignored in future.
Functions that call either `FlushUndoFile` or `FlushBlockFile`, need to handle these extra abort cases properly. Since `Chainstate::FlushStateToDisk` already produces an abort error in case of `WriteBlockIndexDB` failing, no extra logic for functions calling `Chainstate::FlushStateToDisk` is required.
Besides `Chainstate::FlushStateToDisk`, `FlushBlockFile` is also called by `FindBlockPos`, while `FlushUndoFile` is only called by `FlushBlockFile` and `WriteUndoDataForBlock`. For both these cases, the flush error is not further bubbled up. Instead, the error is logged and a comment is provided why bubbling up an error would be less desirable in these cases.
---
This pull request is part of a larger effort towards improving the shutdown / abort / fatal error handling in validation code. It is a first step towards implementing proper fatal error return type enforcement similar as proposed by theuni in this pull request [comment](https://github.com/bitcoin/bitcoin/pull/27711#issuecomment-1563561502). For ease of review of these critical changes, a first step would be checking that `AbortNode` leads to early and error-conveying returns at its call site. Further work for enforcing returns when `AbortNode` is called is done in https://github.com/bitcoin/bitcoin/pull/27862.

Pull request description:
Motivation
- I think it's preferable to use stdlib data structures instead of depending on boost if we can achieve the same thing.
- Also see #28335 for further context/motivation. This PR simplifies that one.
Things done in this PR:
- Add a bench for `DisconnectedBlockTransactions` where we reorg and the new chain has {100%, 90%, 10%} of the same transactions. AFAIU in practice, it's usually close to 100%.
- Rewrite `DisconnectedBlockTransactions` as a `std::list` + `unordered_map` instead of a boost multi index container.
- On my machine, the bench suggests the performance is very similar.
- Move `DisconnectedBlockTransactions` from txmempool.h to its own kernel/disconnected_transactions.h. This struct isn't used by txmempool and doesn't have much to do with txmempool. My guess is that it's been living there for convenience since the boost includes are there.

This was only explicitly used in the tests, where it can be replaced by
wrapping the original raw file pointer into a CAutoFile on creation and
then calling CAutoFile::fclose().
Also, it was used in LoadExternalBlockFile(), where it can also be
replaced by the (implicit call to the) CAutoFile destructor after
wrapping the original raw file pointer in a CAutoFile.

Pull request description:
This removes the non-consensus critical `protocol.h` and `netaddress.h` headers from the kernel headers. With this patch, they are no longer required to include in order to use the libbitcoinkernel library. This also allows for the removal of the `compat.h` header from the kernel headers.
As an added future benefit it also reduces the number of of kernel headers that include the platform specific `bitcoin-config.h`.
For those interested, the currently required kernel headers can be inspected visually with the [sourcetrail](https://github.com/CoatiSoftware/Sourcetrail) tool by looking at the required includes of `bitcoin-chainstate.cpp`.

Pull request description:
While we are evaluating a package, we split it into "subpackages" for evaluation (currently subpackages all have size 1 except the last one). If a subpackage has size 1, we may add a tx to mempool and call `LimitMempoolSize()`, which evicts transactions if the mempool gets full. We handle the case where the just-submitted transaction is evicted immediately, but we don't handle the case in which a transaction from a previous subpackage (either just submitted or already in mempool) is evicted. Mainly, since the coins created by the evicted transaction are cached in `m_view`, we don't realize the UTXO has disappeared until `CheckInputsFromMempoolAndCache` asserts that they exist. Also, the returned `PackageMempoolAcceptResult` reports that the transaction is in mempool even though it isn't anymore.
Fix this by not calling `LimitMempoolSize()` until the very end, and editing the results map with "mempool full" if things fall out.
