508d05f8a7b511dd53f543df8899813487eb03e5 [fuzz] Don't use afl++ deferred forkserver mode (dergoegge)
Pull request description:
Fixes#28469
This makes our afl++ harness essentially behave like libFuzzer, with the exception that the whole program does fully reset every 100000 iterations. 100000 is somewhat arbitrary and we could also go with `std::numeric_limits<unsigned in>::max()` but a smaller limit does allow for the occasional reset to counter act some amount of instability in the fuzzing loop (e.g. non-determinism, statefulness).
It's a bit of a shame to do this just for the targets whose initial state can't be forked (e.g. threads) because other targets do benefit from not having to redo the state setup. An alternative would be https://github.com/bitcoin/bitcoin/issues/28469#issuecomment-1717526774:
```
If the goal is to be maximally performant, the fork would need to happen for each fuzz target specifically.
I guess it can be achieved by wrapping __AFL_INIT(); into a helper function and then require all fuzz
target initialize() to call it?

3fcd7fc7ff563bdc0e2bba66b4cbe72d898c876e Do not use std::vector = {} to release memory (Pieter Wuille)
Pull request description:
It appears that invoking `v = {};` for an `std::vector<...> v` is equivalent to `v.clear()`, which does not release its allocated memory. There are a number of places in the codebase where it appears to be used for that purpose however (mostly written by me). Replace those with `std::vector<...>{}.swap(v);` (using a helper function `ClearShrink` in util/vector.h).
To explain what is going on: `v = {...};` is equivalent in general to `v.operator=({...});`. For many types, the `{}` is converted to the type of `v`, and then assigned to `v` - which for `std::vector` would ordinarily have the effect of clearing its memory (constructing a new empty vector, and then move-assigning it to `v`). However, since `std::vector<T>` has an `operator=(std::initializer_list<T>)` defined, it has precedence (since no implicit conversion is needed), and with an empty list, that is equivalent to `clear()`.
I did consider using `v = std::vector<T>{};` as replacement for `v = {};` instances where memory releasing is desired, but it appears that it does not actually work universally either. `V{}.swap(v);` does.

Reduces the effective value of unconfirmed UTXOs by the fees necessary to bump their ancestor transactions to the same feerate.
While the individual UTXOs always account for their full ancestry before coin-selection, we can correct potential overestimates with a second pass where we establish the ancestry and bump fee for the whole input set collectively.

Deferring the forkserver initialization doesn't make sense for some of
our targets since they involve state that can't be forked (e.g.
threads). We therefore remove the use of __AFL_INIT entirely.
We also increase the __AFL_LOOP count to 100000. Our fuzz targets are
meant to all be deterministic and stateless therefore this should be
fine.

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`.

When a transaction uses an unconfirmed input, preceding this commit it
would not consider the feerate of the parent transaction. Given a parent
transaction with a lower ancestor feerate, this resulted in the new
transaction's ancestor feerate undershooting the target feerate.
This commit changes how we calculate the effective value of unconfirmed UTXOs.
The effective value of unconfirmed UTXOs is decreased by the fee
necessary to bump its ancestry to the target feerate. This also impacts
the calculation of the waste metric: since the estimate for the current
fee is increased by the bump fees, unconfirmed UTXOs current fees appear less
favorable compared to their unchanged long term fees.
This has one caveat: if multiple UTXOs have overlapping ancestries, each
of their individual estimates will account for bumping all ancestors.
GetSelectionWaste will need to access more context within a selection
result, and so should be a private member function rather than a static
function. It's only use outside of SelectionResult was for tests which
have now been updated to just make a SelectionResult.

Follow-up from #27021: accessing of fields in MiniMinerMempoolEntry was
done inconsistently. Even though we had a getter, we would directly
write to the fields when we needed to update them.
This commits sets the fields to private and introduces a method for
updating the ancestor information in transactions using the same method
name as used for Mempool Entries.

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.

Test for scenario(s) outlined in PR 28251.
Test what happens when a package transaction spends a mempool coin which
is fetched and then disappears mid-package evaluation due to eviction or
replacement.
We want to be able to re-use fill_mempool so that none of the tests
affect each other.
Change the logs from info to debug because they are otherwise repeated
many times in the test output.
Don't do any mempool evictions until package validation is done,
preventing the mempool minimum feerate from changing. Whether we submit
transactions separately or as a package depends on whether they meet the
mempool minimum feerate threshold, so it's best that the value not
change while we are evaluating a package.
This avoids a situation where we have a CPFP package in which
the parents meet the mempool minimum feerate and are submitted by
themselves, but they are evicted before we have submitted the child.
Bug fix: a transaction may be in the mempool when package evaluation
begins (so it is added to results_final with MEMPOOL_ENTRY or
DIFFERENT_WITNESS), but get evicted due to another transaction
submission.
Instead of populating the last PackageMempoolAcceptResult with stuff
from results_final and individual_results_nonfinal, fill results_final
and create a PackageMempoolAcceptResult using that one.
A future commit will add LimitMempoolSize() which may change the status
of each of these transactions from "already in mempool" or "submitted to
mempool" to "no longer in mempool". We will change those transactions'
results here.
A future commit also gets rid of the last AcceptSubPackage outside of
the loop. It makes more sense to use results_final as the place where
all results end up.
(1) Call AcceptSingleTransaction when there is only 1 transaction in the
subpackage. This avoids calling PackageMempoolChecks() which enforces
rules that don't need to be applied for a single transaction, i.e.
disabling CPFP carve out.
There is a slight change in the error type returned, as shown in the
txpackage_tests change. When a transaction is the last one left in the
package and its fee is too low, this returns a PCKG_TX instead of
PCKG_POLICY. This interface is clearer; "package-fee-too-low" for 1
transaction would be a bit misleading.
(2) Clean up m_view and m_viewmempool so that coins created in this
sub-package evaluation are not available for other sub-package
evaluations. The contents of the mempool may change, so coins that are
available now might not be later.
Temporary coins should not be available in separate subpackage submissions.
Any mempool coins that are cached in m_view should be removed whenever
mempool contents change, as they may be spent or no longer exist.
Duplicates of normal transactions would be found by looking for
conflicting inputs, but this doesn't catch identical empty transactions.
These wouldn't be valid but exiting early is good and AcceptPackage's
result sanity checks assume non-duplicate transactions.

4614332fc4514f63fcbe9e6de507f7bb9b7e87e9 test: remove unnecessary finalizepsbt rpc calls (ismaelsadeeq)
e3d484b603abff69c6ebfca5cfb78cf82743d090 wallet rpc: return final tx hex from walletprocesspsbt if complete (Matthew Zipkin)
Pull request description:
See https://github.com/bitcoin/bitcoin/pull/28363#discussion_r1315753887
`walletprocesspsbt` currently returns a base64-encoded PSBT and a boolean indicating if the tx is "complete". If it is complete, the base64 PSBT can be finalized with `finalizepsbt` which returns the hex-encoded transaction suitable for `sendrawtransaction`.
With this patch, `walletprocesspsbt` return object will ALSO include the broadcast-able hex string if the tx is already final. This saves users the extra step of calling `finalizepsbt` assuming they have already inspected and approve the transaction from earlier steps.

fabb419a3caafc00fbbc533fee14fab7a5d2a2c6 doc: Clarify that -fstack-reuse=all bugs exist on all versions of GCC (MarcoFalke)
Pull request description:
This is a follow-up to commit 7b850bc2a1cd8547a2dbb5a18173f53439601220. While the test case no longer reproduces, the general class of `-fstack-reuse` bugs still exists in all versions of GCC. The workaround can never be removed, unless the whole class of bugs is fixed.

Pull request description:
This option was introduced in #9194 to ease the transition to segwit; now that most libraries and apps have been updated it should no longer be necessary.
