This is done in preparation for the next two commits, where the
CMainSignals are de-globalized.
This avoids adding new constructor arguments to the ChainstateManager
and CTxMemPool classes over the next two commits.
This could also allow future tests that are only interested in the
internal behaviour of the classes to forgo instantiating the signals.

See #27463 for overall package relay tracking.
Delving Bitcoin discussion thread: https://delvingbitcoin.org/t/v3-transaction-policy-for-anti-pinning/340
Delving Bitcoin discussion for LN usage: https://delvingbitcoin.org/t/lightning-transactions-with-v3-and-ephemeral-anchors/418
Rationale:
- There are various pinning problems with RBF and our general ancestor/descendant limits. These policies help mitigate many pinning attacks and make package RBF feasible (see #28984 which implements package RBF on top of this). I would focus the most here on Rule 3 pinning. [1][2]
- Switching to a cluster-based mempool (see #27677 and #28676) requires the removal of CPFP carve out, which applications depend on. V3 + package RBF + ephemeral anchors + 1-parent-1-child package relay provides an intermediate solution.
V3 policy is for "Priority Transactions." [3][4] It allows users to opt in to more restrictive topological limits for shared transactions, in exchange for the more robust fee-bumping abilities that offers. Even though we don't have cluster limits, we are able to treat these transactions as having as having a maximum cluster size of 2.
Immediate benefits:
- You can presign a transaction with 0 fees (not just 1sat/vB!) and add a fee-bump later.
- Rule 3 pinning is reduced by a significant amount, since the attacker can only attach a maximum of 1000vB to your shared transaction.
This also enables some other cool things (again see #27463 for overall roadmap):
- Ephemeral Anchors
- Package RBF for these 1-parent-1-child packages. That means e.g. a commitment tx + child can replace another commitment tx using the child's fees.
- We can transition to a "single anchor" universe without worrying about package limit pinning. So current users of CPFP carve out would have something else to use.
- We can switch to a cluster-based mempool [5] (#27677 #28676), which removes CPFP carve out [6].

Pull request description:
***Please refer to the [topic on Delving Bitcoin](https://delvingbitcoin.org/t/gutterguard-and-coingrinder-simulation-results/279) discussing Gutter Guard/Coingrinder simulation results.***
Adds a coin selection algorithm that minimizes the weight of the input set while creating change.
Motivations
---
- At high feerates, using unnecessary inputs can significantly increase the fees
- Users are upset when fees are relatively large compared to the amount sent
- Some users struggle to maintain a sufficient count of UTXOs in their wallet
Approach
---
So far, Bitcoin Core has used a balanced approach to coin selection, where it will generate multiple input set candidates using various coin selection algorithms and pick the least wasteful among their results, but not explicitly minimize the input set weight. Under some circumstances, we _do_ want to minimize the weight of the input set. Sometimes changeless solutions require many or heavy inputs, and there is not always a changeless solution for Branch and Bound to find in the first place. This can cause expensive transactions unnecessarily. Given a wallet with sufficient funds, `CoinGrinder` will pick the minimal-waste input set for a transaction with a change output. The current implementation only runs `CoinGrinder` at feerates over 3×long-term-feerate-estimate (by default 30 ṩ/vB), which may be a decent compromise between our goal to reduce costs for the users, but still permit transactions at lower feerates to naturally reduce the wallet’s UTXO pool to curb bloat.
Trade-offs
---
Simulations for my thesis on coin selection ([see Section 6.3.2.1 [PDF]](https://murch.one/erhardt2016coinselection.pdf)) suggest that minimizing the input set for all transactions tends to grind a wallet’s UTXO pool to dust (pun intended): an approach selecting inputs per coin-age-priority (in effect similar to “largest first selection”) on average produced a UTXO pool with 15× the UTXO count as Bitcoin Core’s Knapsack-based Coin Selection then (in 2016). Therefore, I do not recommend running `CoinGrinder` under all circumstances, but only at extreme feerates or when we have another good reason to minimize the input set for other reasons. In the long-term, we should introduce additional metrics to score different input set candidates, e.g. on basis of their privacy and wallet health impact, to pick from all our coin selection results, but until then, we may want to limit use of `CoinGrinder` in other ways.

Given a lot of small amount UTXOs it is possible that the lookahead
indicates sufficient funds, but any combination of them would push us
beyond the current best_weight.
We can estimate a lower bound for the minimal necessary weight to reach
target from the maximal amount and minimal weight in the tail of the
UTXO pool: if adding a number of hypothetical UTXOs of this maximum
amount and minimum weight would not be able to beat `best_weight`, we
can SHIFT to the omission branch, and CUT if the last selected UTXO is
not heavier than the minimum weight of the remainder.
|
|
Initialize `best_selection_weight` as `max_weight` allows us to skip the
separate `max_weight` check on every loop.
|
|
In situations where we have UTXO groups of various weight, we can CUT
rather than SHIFT when we exceeded the max_weight or the best
selection’s weight while the last step was equal to the minimum weight
in the lookahead.
|
|
When two successive UTXOs differ in weight but match in effective value,
we can skip the second if the first is not selected, because all input
sets we can generate by swapping out a lighter UTXOs with a heavier UTXO
of matching effective value would be strictly worse.
|
|
|
|
When two successive UTXOs match in effective value and weight, we can
skip the second if the prior is not selected: adding it would create an
equivalent input set to a previously evaluated.
E.g. if we have three UTXOs with effective values {5, 3, 3} of the same
weight each, we want to evaluate
{5, _, _}, {5, 3, _}, {5, 3, 3}, {_, 3, _}, {_, 3, 3},
but skip {5, _, 3}, and {_, _, 3}, because the first 3 is not selected,
and we therefore do not need to evaluate the second 3 at the same
position in the input set.
If we reach the end of the branch, we must SHIFT the previously selected
UTXO group instead.
|
|
Introduces a dedicated data structure to track the total
effective_value available in the remaining UTXOs at each index of the
UTXO pool. In contrast to the approach in BnB, this allows us to
immediately jump to a lower index instead of visiting every UTXO to add
back their eff_value to the lookahead.
|
|
Once we exceed the weight of the current best selection, we can always
shift as adding more inputs can never yield a better solution.

CoinGrinder may not be able to exhaustively search all potentially
interesting combinations for large UTXO pools, so we keep track of
whether the search was terminated by the iteration limit.
|
|
|
|
CoinGrinder is a DFS-based coin selection algorithm that
deterministically finds the input set with the lowest weight creating a
change output.

Pull request description:
`make check` runs a bunch of other subtree tests that exercise code that is hardly ever changed and have a comparatively long runtime. There seems to be no target for running just the unit tests, so add one.
Alternatively the secp256k1 tests could be removed from the `check-local` target, reducing its runtime. This was rejected before though in https://github.com/bitcoin/bitcoin/pull/20264.

395bcd245476d7c83abf2d82e31e90b6d0c432f3 sqlite: Ensure that only one SQLiteBatch is writing to db at a time (Ava Chow)
Pull request description:
The way that we have configured SQLite to run means that only one database transaction can be open at a time. Typically, each individual read and write operation will be its own transaction that is opened and committed automatically by SQLite. However, sometimes we want these operations to be batched into a multi-statement transaction, so `SQLiteBatch::TxnBegin`, `SQLiteBatch::TxnCommit`, and `SQLiteBatch::TxnAbort` are used to manage the transaction of the database.
However, once a db transaction is begun with one `SQLiteBatch`, any operations performed by another `SQLiteBatch` will also occur within the same transaction. Furthermore, those other `SQLiteBatch`s will not be expecting a transaction to be active, and will abort it once the `SQLiteBatch` is destructed. This is problematic as it will prevent some data from being written, and also cause the `SQLiteBatch` that opened the transaction in the first place to be in an unexpected state and throw an error.
To avoid this situation, we need to prevent the multiple batches from writing at the same time. To do so, I've implemented added a `CSemaphore` within `SQLiteDatabase` which will be used by any `SQLiteBatch` trying to do a write operation. `wait()` is called by `TxnBegin`, and at the beginning of `WriteKey`, `EraseKey`, and `ErasePrefix`. `post()` is called in `TxnCommit`, `TxnAbort` and at the end of `WriteKey`, `EraseKey`, and `ErasePrefix`. To avoid deadlocking on ` TxnBegin()` followed by a `WriteKey()`, `SQLiteBatch will now also track whether a transaction is in progress so that it knows whether to use the semaphore.
This issue is not a problem for BDB wallets since BDB uses WAL and provides transaction objects that must be used if an operation is to occur within a transaction. Specifically, we either pass a transaction pointer, or a nullptr, to all BDB operations, and this allows for concurrent transactions so it doesn't have this problem.

Pull request description:
Found it while reviewing other PR. Couldn't contain myself from cleaning it up.
The wallet decryption process (`CheckDecryptionKey()` and `Unlock()`)
contains an arg 'accept_no_keys,' introduced in #13926, that has
never been used.
Additionally, this also removes the unimplemented `SplitWalletPath`
function.

Verifying that a database handler can't commit/abort changes
occurring in a different database handler.
|
|
A SQLiteBatch need to wait for any other batch to finish writing before
it can begin writing, otherwise db txn state may be incorrectly
modified. To enforce this, each SQLiteDatabase has a semaphore which
acts as a lock and is acquired by a batch when it begins a write, erase,
or a transaction, and is released by it when it is done.
To avoid deadlocking on itself for writing during a transaction,
SQLiteBatch also keeps track of whether it has begun a transaction.

mandatory and few cleanups
e7fd70f4b6b163f4ad5b25b4da7fa79899245235 [test] make v2transport arg in addconnection mandatory and few cleanups (stratospher)
Pull request description:
- make `v2transport` argument in `addconnection` regression-testing only RPC mandatory. https://github.com/bitcoin/bitcoin/pull/24748#discussion_r1470738750
- previously it was an optional arg with default `false` value.
- only place this RPC is used is in the [functional tests](https://github.com/bitcoin/bitcoin/blob/11b436a66af3ceaebb0f907878715f331516a0bc/test/functional/test_framework/test_node.py#L742) where we always pass the appropriate `v2transport` option to the RPC anyways. (and that too just for python dummy peer(`P2PInterface`) and bitcoind(`TestNode`) interactions)
- rename `v2_handshake()` to `_on_data_v2_handshake()` https://github.com/bitcoin/bitcoin/pull/24748#discussion_r1466958424
- more compact return statement in `wait_for_reconnect()` https://github.com/bitcoin/bitcoin/pull/24748#discussion_r1466979708
- assertion to check that empty version packets are received from `TestNode`.

9332c7edda79a39bb729b71b6f8db6a9d37343bb wallet: Write bestblock to watchonly and solvable wallets (Ava Chow)
Pull request description:
A transaction does not necessarily have to belong to either the migrated wallet (with the private keys) and the watchonly wallet (with watchonly things), it could have multiple outputs with each isminetype. So we should be putting such transactions in one or the other wallet, but rather putting it in both.
I've added a test for this behavior, however the test also revealed a few other issues. Notably, it revealed that `migratewallet` would have the watchonly wallet rescan from genesis when it is reloaded at the end of migration. This could be a cause for migration appearing to be very slow. This is resolved by first writing best block records to the watchonly and solvable wallets, as well as updating the test to make sure that rescans don't happen.
The change to avoid rescans also found an issue where some of our early exits would result in unloading the wallet even though nothing happened. So there is also a commit to reload the wallet for such early exits.

blank wallets

072d506240f6c39387b2edd4421818cc914c0912 wallet: Make sure that the descriptors flag is set for blank wallets (Ava Chow)
Pull request description:
While rebasing #28710 after #28976 was merged, I realized that although blank wallets were being moved to sqlite, `WALLET_FLAG_DESCRIPTORS` was not being set so those blank wallets would still continue to be treated as legacy wallets.
To fix that, just set the descriptor flags for blank wallets. Also added a test to catch this.
