2de222c401 wallet: Use GetSelectionAmount for target value calculations (Andrew Chow)
Pull request description:
The `m_value` used for the target calculation in `ApproximateBestSubset` is incorrect, it should be `GetSelectionAmount`. This causes a bug that is only apparent when the minimum relay fee is set to be very high.
A test case is added for this, in addition to an assert in `CreateTransactionInternal` that would have also caught this issue if someone were able to hit the edge case.

ae23faba6f Add a new RPC command: restorewallet (lsilva01)
Pull request description:
As far as I know, there is no command to restore the wallet from a backup file.
The only way to do this is to replace the `wallet.dat` of a newly created wallet with the backup file, which is hardly an intuitive way.
This PR implements the `restorewallet` RPC command which restores the wallet from the backup file.
To test:
First create a backup file:
`$ bitcoin-cli -rpcwallet="wallet-01" backupwallet /home/Backups/wallet-01.bak`
Then restore it in another wallet:
`$ bitcoin-cli restorewallet "restored-wallet-01" /home/Backups/wallet-01.bak`

4844b74ba7 p2p: log addrman consistency checks (Jon Atack)
Pull request description:
This mini-patch picks up #22479 to log addrman consistency checks in the `BCLOG::ADDRMAN` category when they are enabled with the `-checkaddrman=<n>` configuration option for values of n greater than 0.
```
$ ./src/bitcoind -signet -checkaddrman=20 -debug=addrman
...
2021-08-13T11:14:45Z Addrman checks started: new 3352, tried 89, total 3441
2021-08-13T11:14:45Z Addrman checks completed successfully
```
This allows people to
- verify the checks are running
- see when and how often they are being performed
- see the number of new/tried/total addrman entries per check
- see the start/end of the checks
Thanks to John Newbery for ideas to improve this logging.

Pull request description:
CAddrMan has internal consistency checks. Currently, these are only run when the program is compiled with the `DEBUG_ADDRMAN` option. This option is not enabled on any of our CI builds, and it's likely that no-one is running them at all.
This PR makes consistency checks a (hidden) runtime option that can be enabled with `-checkaddrman`, where `-checkaddrman=n` will result in the consistency checks running every n operations (similar to `-checkmempool=n`). We set the ratio to 1/100 for our unit tests, and leave it disabled by default for all networks. Additionally, a consistency check failure now asserts, rather than logging and continuing. This matches the behavior of CTxMemPool and TxRequestTracker, where a failed consistency check asserts.

ApproximateBestSubset had an edge case (due to not using
GetSelectionAmount) where it was possible for it to return success but
fail to select enough to cover transaction fees. A test is added that
could trigger this failure prior to the fix being implemented.
When the fee is not subtracted from the outputs, the amount that has
been reserved for the fee (change_and_fee - change_amount) must be
enough to cover the fee that is needed. It would be a bug to not do so,
so use an assert to make this obvious if such a situation were to occur.
For target value calculations, GetSelectionAmount should be used, not
m_effective_value or m_value.
Specifically, ApproximateBestSubset mistakenly uses m_value when
calculating whether the target value has been met. This has been changed
to use GetSelectionAmount.

Divided tests in rpc_signmessage.py into 2 files wallet_signmessagewithaddress.py and
rpc_signmessagewithprivkey.py, latter one can run even when wallet is disabled.
Currently addrman consistency checks are a compile time option, and are not
enabled in our CI. It's unlikely anyone is running these consistency checks.
Make them a runtime option instead, where users can enable addrman
consistency checks every n operations (similar to mempool tests). Update
the addrman unit tests to do internal consistency checks every 100
operations (checking on every operations causes the test runtime to
increase by several seconds).
Also assert on a failed addrman consistency check to terminate program
execution.

ad28b66e98 qt: Add SubFeeFromAmount option (Prateek Sancheti)
Pull request description:
This PR adds **_SubFeeFromAmount_** option which lets the user select their preferred setting of whether fee for a transaction is to be subtracted from the amount or not for future transactions. The setting chosen by the user is remembered even when the GUI mode is turned off.
**_Functionality and Usage:_**
- Go to `Settings > Options > Wallet` on _Windows/Linux_ or `bitcoin-qt > Preferences > Wallet` on _macOS_.
- The checkbox **Subtract Fee From Amount** corresponds to the added option **SubFeeFromAmount**.
- The preferred setting intended to be the default for all future send transactions should be selected by the user.
- Click on **OK**.
- Go to the **Send** tab in the wallet.
- You shall notice, any new Send transaction created will have the preferred setting as chosen by the user.<br> (Try clicking on Add recipient or even restarting the Node in GUI)
Attaching ScreenRecordings to explain the added feature.

0237d95323 qt: Add Load PSBT functionaliy with nowallet (Prateek Sancheti)
Pull request description:
This PR provides a fix to the issue mentioned in #232.
Currently, the **_Load PSBT_** functionality works well in case a wallet is loaded but does nothing when a wallet isn't loaded.
If a function cannot work without a wallet being loaded, it is disabled by default (It is unclickable as shown in the image).
For e.g. One cannot `Close Wallet` or `Backup Wallet` or `Sign Messages` without a wallet being loaded. And hence they are disabled. But if you notice, `Load PSBT` options are not disabled by default even when a wallet isn't loaded.
> 
As mentioned by hebasto in the issue description :
```
<hebasto> achow101: does "File" -> "Load PSBT from {file|clipboard}" make any sense when no wallet is loaded?
<achow101> hebasto: yes, for finalize and sending
```
This means **_Load PSBT_** should be working just as similar whether wallets are being loaded or not.
After making the required changes to the code, The **_Load PSBT_** works as expected even with no wallet loaded and the PSBT is finalized.

Pull request description:
This PR implements a function to calculate mempool ancestors for a package and enforces ancestor/descendant limits on them as a whole. It reuses a portion of `CalculateMemPoolAncestors()`; there's also a small refactor to move the reused code into a generic helper function. Instead of calculating ancestors and descendants on every single transaction in the package and their ancestors, we use a "worst case" heuristic, treating every transaction in the package as each other's ancestor and descendant. This may overestimate everyone's counts, but is still pretty accurate in the our main package use cases, in which at least one of the transactions in the package is directly related to all the others (e.g. 1 parent + 1 child, multiple parents with 1 child, or chains).
Note on Terminology: While "package" is often used to describe groups of related transactions _within_ the mempool, here, I only use package to mean the group of not-in-mempool transactions we are currently validating.
#### Motivation
It would be a potential DoS vector to allow submission of packages to mempool without a proper guard for mempool ancestors/descendants. In general, the purpose of mempool ancestor/descendant limits is to limit the computational complexity of dealing with families during removals and additions. We want to be able to validate multiple transactions on top of the mempool, but also avoid these scenarios:
- We underestimate the ancestors/descendants during package validation and end up with extremely complex families in our mempool (potentially a DoS vector).
- We expend an unreasonable amount of resources calculating everyone's ancestors and descendants during package validation.

Pull request description:
In a couple of places in the wallet, errors are `std::string`. In order for these errors to be translated, change them to use `bilingual_str`.

fa6fd3dd6a wallet: Properly set fInMempool in mempool notifications (MarcoFalke)
Pull request description:
A wallet method (like bumping the fee) might have set `fInMempool` to false because the transaction was removed from the mempool (See commit fa4e088cba).
Avoid setting it back to true (incorrectly) in the validation interface background thread.
Fixes#22357

Code review ACK fa6fd3dd6a. Only change since last review is extending workaround to `transactionRemovedFromMempool`. Since we know this workaround is imperfect and the goal of this PR is mainly to fix CI errors, I would probably be inclined to limit the workaround to as few places as possible where we have seen actual failures, instead of adding the workaround to as many places as possible, where there is some chance it might trigger new failures. But since this workaround is so straightforward and almost looks like a real fix, probably it doesn't matter.

bb822a7af8 wallet, rpc: add listdescriptors private option (S3RK)
Pull request description:
Rationale: make it possible to backup your wallet with `listdescriptors` command
* The default behaviour is still to show public version
* For private version only the root xprv is returned
Example use-case:
```
> bitcoin-cli -regtest -named createwallet wallet_name=old descriptors=true
> bitcoin-cli -regtest -rpcwallet=old listdescriptors true | jq '.descriptors' > descriptors.txt
> bitcoin-cli -regtest -named createwallet wallet_name=new descriptors=true blank=true
> bitcoin-cli -regtest -rpcwallet=new importdescriptors "$(cat descriptors.txt)"
```
In case of watch-only wallet without private keys there will be following output:
```
error code: -4
error message:
Can't get descriptor string.
```
