Pull request description:
Currently, `unloadwallet` RPC call fails with a JSON parsing error when no `wallet_name` argument is provided. This behavior is misleading because the error originates from a low-level JSON type mismatch, rather than clearly indicating that the wallet name or RPC endpoint (`-rpcwallet=...`) is missing. Also, found out that the [issue](https://github.com/bitcoin/bitcoin/pull/13111#issuecomment-398831543) was noticed during its implementation but never addressed.
In addition, I've verified all RPC commands calls finding that `getdescriptoractivity` had the same problem, but related to the array input types (blockhashes & descriptors), so I've corrected that RPC as well. For consistency I've added the missing logging info for each test case in `test/functional/rpc_getdescriptoractivity.py` in preparation for the new test.

6135e0553e wallet, rpc: Move (Un)LockCoin WalletBatch creation out of RPC (Ava Chow)
Pull request description:
If the locked coin needs to be persisted to the wallet database, insteead of having the RPC figure out when to create a WalletBatch and having LockCoin's behavior depend on it, have LockCoin take whether to persist as a parameter so it makes the batch.
Since unlocking a persisted locked coin requires a database write as well, we need to track whether the locked coin was persisted to the wallet database so that it can erase the locked coin when necessary.
Keeping track of whether a locked coin was persisted is also useful information for future PRs.

This argument might have been used in the legacy wallets, but I don't
see any implementation using this argument in the SQLite wallets.
Removing it cleans up the code a bit.

Pull request description:
`fclose(3)` may fail to flush the previously written data to disk, thus a failing `fclose(3)` is as serious as a failing `fwrite(3)`.
Previously the code ignored `fclose(3)` failures. This PR improves that by changing all users of `AutoFile` that use it to write data to explicitly close the file and handle a possible error.
---
Other alternatives are:
1. `fflush(3)` after each write to the file (and throw if it fails from the `AutoFile::write()` method) and hope that `fclose(3)` will then always succeed. Assert that it succeeds from the destructor 🙄. Will hurt performance.
2. Throw nevertheless from the destructor. Exception within the exception in C++ I think results in terminating the program without a useful message.
3. (this is implemented in the latest incarnation of this PR) Redesign `AutoFile` so that its destructor cannot fail. Adjust _all_ its users 😭. For example, if the file has been written to, then require the callers to explicitly call the `AutoFile::fclose()` method before the object goes out of scope. In the destructor, as a sanity check, assume/assert that this is indeed the case. Defeats the purpose of a RAII wrapper for `FILE*` which automatically closes the file when it goes out of scope and there are a lot of users of `AutoFile`.
4. Pass a new callback function to the `AutoFile` constructor which will be called from the destructor to handle `fclose()` errors, as described in https://github.com/bitcoin/bitcoin/pull/29307#issuecomment-2243842400. My thinking is that if that callback is going to only log a message, then we can log the message directly from the destructor without needing a callback. If the callback is going to do more complicated error handling then it is easier to do that at the call site by directly calling `AutoFile::fclose()` instead of getting the `AutoFile` object out of scope (so that its destructor is called) and inspecting for side effects done by the callback (e.g. set a variable to indicate a failed `fclose()`).

Pull request description:
Currently, the migration process creates a brand-new descriptor wallet with no
connection to the user's legacy wallet when the legacy wallet lacks key material
and contains only watch-only scripts. This behavior is not aligned with user
expectations. If the legacy wallet contains only watch-only scripts, the migration
process should only generate a watch-only wallet instead.
TODO List:
* Explain that `migratewallet` renames the watch-only after migration, and
also that the wallet will not have keys enabled.

There is no way to report a close error from `AutoFile` destructor.
Such an error could be serious if the file has been written to because
it may mean the file is now corrupted (same as if write fails).
So, change all users of `AutoFile` that use it to write data to
explicitly close the file and handle a possible error.
Historically, the headers have been bumped some time after a file has
been touched. Do it now to avoid having to touch them again in the
future for that reason.

785e1407b0 wallet: Use util::Error throughout AddWalletDescriptor (Ava Chow)
Pull request description:
#32023 changed `AddWalletDescriptor` to return `util::Error`, but did not change all of the failure cases to do so. This may result in some callers continuing when there was actually an error. Unify all of the failure cases to use `util::Error` so that all callers handle `AddWalletDescriptor` errors in the same way.
The encapsulated return type is changed from `ScriptPubKeyMan*` to `std::reference_wrapper<DescriptorScriptPubKeyMan>`. This avoids having a value that can be interpreted as a bool, and also removes the need to constantly dynamic_cast the returned value. The only kind of `ScriptPubKeyMan` that can come out of `AddWalletDescriptor` is a `DescriptorScriptPubKeyMan` anyways.

Pull request description:
Currently, we do not add the sighash field to PSBTs at all, even when we have signed with a non-default sighash. This PR changes the behavior such that when we (attempt to) sign with a sighash other than DEFAULT or ALL, the sighash type field will be added to the PSBT to inform the later signers that a different sighash type was used by a signer. Notably, this is necessary for MuSig2 support as all signers must sign using the same sighash type, but the sighash is not provided in partial signatures.
Furthermore, because the sighash type can also be provided on the command line, we require that if both a command line sighash type and the sighash field is present, they must specify the same sighash type. However, this was being checked by the wallet, rather than the signing code, so the `descriptorprocesspsbt` RPC was not enforcing this restriction at all, and in fact ignored the sighash field entirely. This PR refactors the checking code so that the underlying PSBT signing function `SignPSBTInput` does the check.

Pull request description:
Implements the idea discussed in https://github.com/bitcoin/bitcoin/pull/29652#issuecomment-2010579484
Currently, `m_last_block_processed` and `m_last_block_processed_height` are not guaranteed to match the block locator stored in the wallet, nor do either of those fields actually represent the last block that the wallet is synced up to. This is confusing and unintuitive.
This PR changes those last block fields to be updated whenever the wallet makes a change to the db for new transaction state found in new blocks. Whenever a block is received that contains a transaction relevant to the wallet, the last block locator will now be written to disk. Furthermore, every block disconnection will now write an updated locator.
To ensure that the locator is relatively recent and loading rescans are fairly quick in the event of unplanned shutdown, it is also now written every 144 blocks (~1 day). Additionally it is now written when the wallet is unloaded so that it is accurate when the wallet is loaded again.
Lastly, the `chainstateFlushed` notification in the wallet is changed to be a no-op. The best block locator record is no longer written when `chainstateFlushed` is received from the node since it should already be mostly up to date.

Instead of having the caller have to figure out the correct sane default
to provide to FillPSBT, have FillPSBT do that by having it take the
sighash type as an optional. This further allows it to distinguish
between an explicit sighash type being provided and expecting the
default value to be used.
When a block is connected, if the new block had anything relevant to the
wallet, update the best block record on disk. If not, also sync the best
block record to disk every 144 blocks.
Also reuse the new WriteBestBlock method in BackupWallet.

I aim to completely replace `coinselector_tests` with `coinselection_tests`.

We do not need to repeat the same test multiple times because BnB is
deterministic and will therefore always have the same outcome.
Additionally, this test was redundant because it repeats the "Smallest
combination too big" test.
Originally these tests verified that at a SelectCoins level that a
solution with fewer inputs gets preferred at high feerates, and a
solution with more inputs gets preferred at low feerates. This outcome
relies on the behavior of BnB, so we move these tests under the umbrella
of BnB tests.
Originally these tests relied on SFFO to work.
Recreates the tests in a new test suite coinselection_tests.cpp that is
based on UTXOs being created per their effective values rather than
nominal values and uses transactions with non-zero feerates.

Also, mentions of the never-implemented derivation method `scrypt` are removed from the wallet crypter header and both plain and encrypted master key instances are renamed to adapt to moderning coding style (hopefully improving readability).

after this fix improved performance of importdescriptor part refs https://github.com/bitcoin/bitcoin/issues/32013.
**Steps to reproduce in testnet environment**
**Input size:** 2 million address in the wallet
**Step1:** call importaddresdescriptor rpc method
observe the time it has taken.
**With the provided fix:**
Do the same steps again
observe the time it has taken.
There is a huge improvement in the performance. (previously it may take 5 to 6 seconds now it will take 1 seconds or less)
main changes i've made during this pr:
1. remove duplicate call to GetDescriptorScriptPubKeyMan method
2. And inside GetDescriptorScriptPubKeyMan method previously we checking **each address linearly** so each time it is calling HasWallet method which has aquired lock.
3. Now i've modified this logic call **find method on the map (O(logn)**) time it is taking, so only once we calling HasWallet method.
**Note:** Smaller inputs in the wallet you may not see the issue but huge wallet size it will definitely impact the performance.

Legacy wallets do not have the descriptors flag set. Don't load wallets
without the descriptors flag.
At the same time, we will no longer load BDB databases since they are
only used for legacy wallets.
Legacy wallets should only import keys to the keypool if they came in a
single key descriptor. Instead of relying on assumptions about the
descriptor based on how many pubkeys show up after expanding the
descriptor, explicitly mark descriptors as being single key type and use
that for the check.
The new helper will be used to fix a crash in the
wallet migration process (watch-only, non-blank,
private keys disabled, empty wallet - no scripts
or addresses imported).

28dc118001 fuzz: wallet: fix crypter target (brunoerg)
Pull request description:
The crypter target has an issue, it's calling `DecryptKey` with a random secret and a random public key that will unlikely be related to the key used to encrypt, so it won't have any effect. This PR changes fixes it and also removes the `DecryptSecret` call since this function is already (and only) called within `DecryptKey`.
