2024-02-09opt: Skip evaluation of equivalent input setsMurch
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.
2024-02-09opt: Track remaining effective_value in lookaheadMurch
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.
2024-02-09opt: Skip branches with worse weightMurch
Once we exceed the weight of the current best selection, we can always shift as adding more inputs can never yield a better solution.

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.

If the db handler that initiated the database transaction is destroyed, the ongoing transaction cannot be left dangling when the db txn fails to abort. It must be forcefully reverted; otherwise, any subsequent db handler executing a write operation will dump the dangling, to-be-reverted transaction data to disk. This not only breaks the isolation property but also results in the improper storage of incomplete information on disk, impacting the wallet consistency. This PR fixes the issue by resetting the db connection, automatically rolling back the transaction (per https://www.sqlite.org/c3ref/close.html) when the handler object is being destroyed and the txn abortion failed. Testing Notes Can verify the failure by reverting the fix e5217fea and running the test. It will fail without e5217fea and pass with it.

2024-01-19refactor: pass CRecipient to FundTransactionjosibake
Instead turning tx.vout into a vector of `CRecipient`, make `FundTransaction` take a `CRecipient` vector directly. This allows us to remove SFFO logic from the wrapper RPC `FundTransaction` since the `CRecipient` objects have already been created with the correct SFFO values. This also allows us to remove SFFO from both `FundTransaction` function signatures. This sets us up in a future PR to be able to use these RPCs with BIP352 static payment codes.
