Pull request description:
Currently inactive HD chains are only derived from at the time a key in that chain is found to have been used. However, at that time, the wallet may not be able to derive keys (e.g. it is locked). Currently we would just move on and not derive any new keys, however this could result in missing funds.
This PR resolves this problem by adding memory only variables to `CHDChain` which track the highest known index. `TopUp` is modified to always try to top up the inactive HD chains, and this process will use the new variables to determine how much to top up. In this way, after an encrypted wallet is unlocked, the inactive HD chains will be topped up and hopefully funds will not be missed.
Note that because these variables are not persisted to disk (because `CHDChain`s for inactive HD chains are not written to disk), if an encrypted wallet is not unlocked in the same session as a key from an inactive chain is found to be used, then it will not be topped up later unless more keys are found.
Additionally, wallets which do not have upgraded key metadata will not derive any keys from inactive HD chains. This is resolved by using the derivation path string in `CKeyMetadata.hdKeypath` to determine what indexes to derive.

Refactors TopUp so that it also tops up inactive chains. The bulk of
TopUp is moved to TopUpChain.
CHDChain also has 2 new in memory variables to track its highest used
indexes. This is used only for inactive hd chains so that they can be
topped up later in the same session (e.g. if the wallet is encrypted and
not unlocked at the time of MarkUnusedAddresses).

456e350926adde5dabdbc85fc0f017fb29bdadb3 wallet: resolve ambiguity of two ScriptPubKey managers providing same script (S3RK)
Pull request description:
This PR fixes certain use-cases when **send-to-self** transactions are missing from `listtransactions` output.
1. When a receiving address is generated externally to the wallet
(e.g. same wallet running on two nodes, or by 3rd party from xpub)
2. When restoring backup with lost metadata, but keypool gap is not exceeded yet
When the block is connected or tx added to mempool we already mark used keys. This PR extends this logic to determine whether the destination is a receiving one and if yes add it to the address book with empty label.
Works both for legacy and descriptors wallets.
- For legacy it uses the internal flag from the keypool entry. Caveat: because we don't know which script type would be used we add all possible destinations for such keys.
- For descriptor wallets it uses internal flag for the script pub key manager. Caveat: it only works for active descriptors.

a99ed8986554fa1ecc854e43ea373d957e598db8 psbt: sign without finalizing (Andrew Chow)
Pull request description:
It can be useful to sign an input with `walletprocesspsbt` but not finalize that input if it is complete. This PR adds another option to `walletprocesspsbt` to be able to do that. We will still finalize by default.
This does not materially change the PSBT workflow since `finalizepsbt` needs to be called in order to extract the tx for broadcast.

If a ScriptPubKeyMan does not implement Upgrade, then using upgraewallet
will fail unexpectedly. By changing the default to return true, then
this error can be avoided. This is still correct because a successful
upgrade can be that nothing happened.

Pull request description:
Rationale: improve consistency between `CWallet` and `DescriptorScriptPubKeyMan`; simplify `ScriptPubKeyMan` interface.
Descriptor in itself is neither internal or external. It's responsibility of a wallet to assign and manage descriptors for a specific purpose. Duplicating information about internalness of a descriptor could lead to inconsistencies and unexpected behaviour (for example misreporting keypool size).

bf68ebc1cd555f791103f81adc9111e0e55c8003 wallet: allow to import same descriptor twice (S3RK)
Pull request description:
Rationale: allow updating existing descriptors with `importdescriptors` command.
Currently if you run same `importdescriptors` command twice with a descriptor containing private key you will get very confusing error — `Missing required fields`. What happens is that Wallet tries to write imported private key to the disk, but it exists already so we get `DB_KEYEXIST (-30995)` from BerkelyDB. Please note, that we set `DB_NOOVERWRITE` (I guess not to lose some keys accidentally). The exception is caught in `catch (...)` in rpcdump.cpp with a generic error.
With this PR if a descriptor is already present than we will update its activeness, internalness, label, range and next_index.
For the range only expansion is allowed (range start can only decrease, range end increase).

Adds an error output parameter to all GetReservedDestination functions
so that callers can get the actual reason that a change address could
not be fetched. This more closely matches GetNewDestination. This allows
for more granular error messages, such as one that indicates that
bech32m addresses cannot be generated yet.

Make sure that LegacyScriptPubKeyMan can only be used for legacy,

Pull request description:
Adds `parent_desc` field to the `getaddressinfo` RPC to export a public descriptor. Using the given address, `getaddressinfo` will look up which `DescriptorScriptPubKeyMan` can be used to produce that address. It will then return the descriptor for that `DescriptorScriptPubKeyMan` in the `parent_desc` field. The descriptor will be in a normalized form where the xpub at the last hardened step is derived so that the descriptor can be imported to other wallets. Tests are added to check that the correct descriptor is being returned for the wallet's addresses and that these descriptors can be imported and used in other wallets.
As part of this PR, a `ToNormalizedString` function is added to the descriptor classes. This really only has an effect on `BIP32PubkeyProvider`s that have hardened derivation steps. Tests are added to check that normalized descriptors are returned.

Pull request description:
This PR cleans up the wallet upgrade mechanism a bit, fixes some probably bugs, and adds more test cases.
The `nWalletMaxVersion` member variable has been removed as it made `CanSupportFeature` unintuitive and was causing a couple of bugs. The reason this was introduced originally was to allow a wallet upgrade to only occur when the new feature is first used. While this makes sense for the old `-upgradewallet` option, for an RPC, this does not quite make sense. It's more intuitive for an upgrade to occur if possible if the `upgradewallet` RPC is used as that's an explicit request to upgrade a particular wallet to a newer version. `nWalletMaxVersion` was only relevant for upgrades to `FEATURE_WALLETCRYPT` and `FEATURE_COMPRPUBKEY` both of which are incredibly old features. So for such wallets, the behavior of `upgradewallet` will be that the feature is enabled immediately without the wallet needing to be encrypted at that time (note that `FEATURE_WALLETCRYPT` indicates support for encryption, not that the wallet is encrypted) or for a new key to be generated.
`CanSupportFeature` would previously indicate whether we could upgrade to `nWalletMaxVersion` not just whether the current wallet version supported a feature. While this property was being used to determine whether we should upgrade to HD and HD chain split, it was also causing a few bugs. Determining whether we should upgrade to HD or HD chain split is resolved by passing into `ScriptPubKeyMan::Upgrade` the version we are upgrading to and checking against that. By removing `nWalletMaxVersion` we also fix a bug where you could upgrade to HD chain split without the pre-split keypool.
`nWalletMaxVersion` was also the version that was being reported by `getwalletinfo` which meant that the version reported was not always consistent across restarts as it depended on whether `upgradewallet` was used. Additionally to make the wallet versions consistent with actually supported versions, instead of just setting the wallet version to whatever is given to `upgradewallet`, we normalize the version number to the closest supported version number. For example, if given 150000, we would store and report 139900.
Another bug where CHDChain was not being upgraded to the version supporting HD chain split is also fixed by this PR.
Lastly several more tests have been added. Some refactoring to the test was made to make these tests easier. These tests check specific upgrading scenarios, such as from non-HD (version 60000) to HD to pre-split keypool. Although not specifically related to `upgradewallet`, `UpgradeKeyMetadata` is now being tested too.
Part of the new tests is checking that the wallet files are identical before and after failed upgrades. To facilitate this, a utility function `sha256sum_file` has been added. Another part of the tests is to examine the wallet file itself to ensure that the records in the wallet.dat file have been correctly modified. So a new `bdb.py` module has been added to deserialize the BDB db of the wallet.dat file. This format isn't explicitly documented anywhere, but the code and comments in BDB's source code in file `dbinc/db_page.h` describe it. This module just dumps all of the fields into a dict.

nWalletMaxVersion was used to allow an upgrade to a version only
when the new feature was used. This makes sense for the old
-upgradewallet startup option. But because upgradewallet is now a RPC,
putting off the version bump like this does not make sense. Instead,
immediately upgrading to the given version number makes sense.
|
|
Instead of using CanSupportFeature and relying on nWalletMaxVersion,
take the new version we are upgrading to and use IsSupportedFeature
with that and the previous wallet version.

0122fbab4c340b23ae56173de6c5ab866ba25ab8 Split SetHDChain into AddHDChain and LoadHDChain (Andrew Chow)
Pull request description:
`SetHDChaiin`, `SetActiveScriptPubKeyMan`, and `SetWalletFlags` have a `memonly` argument which is kind of confusing, as noted in https://github.com/bitcoin/bitcoin/pull/17681#discussion_r427633081. This PR replaces those functions with `Add*` and `Load*` variants so that they follow the pattern used elsewhere in the wallet.
`AddHDChain`, `AddActiveScriptPubKeyMan`, and `AddWalletFlags` both set their respective variables in `CWallet` and writes them to disk. These functions are used by the actions which modify the wallet such as `sethdseed`, `importdescriptors`, and creating a new wallet.
`LoadHDChain`, `LoadActiveScriptPubKeyMan`, and `LoadWalletFlags` just set the `CWallet` variables. These functions are used by `LoadWallet` when loading the wallet from disk.

In FillPSBT, optionally report the number of inputs we successfully
signed, as an out parameter. If "sign" is false, instead report the
number of inputs for which GetSigningProvider does not return nullptr.
(This is a potentially overbroad estimate of inputs we could sign.)

This is the final step 🥳 of the serialization improvements extracted from #10785.
It converts the LimitedString wrapper to a new-style formatter, and updates the wallet and Qt code to use the new serialization framework. Finally all remaining old primitives are removed.

b59b4504abf96cec860badfed2ac793ae5d40ced have GenerateNewKey and DeriveNewChildKey take a CHDChain as an argument (Andrew Chow)
Pull request description:
Largely implements the suggestion from https://github.com/bitcoin/bitcoin/pull/17484#issuecomment-560845316.
After `sethdseed` is called, the CHDChain for the old seed is kept in the wallet. It is kept on the file as a new `inactivehdseed` record and in memory in a map `m_inactive_hd_seeds`. In `LegacyScriptPubKeyMan::MarkUnusedAddresses` we check each used key's metadata for whether it was derived from an inactive seed. If it is, we then check to see how many keys after that key were derived from the inactive seed. If that number does not match the keypool parameter, we derive more keys from the inactive seed until it does match. This way we won't miss transactions belonging to keys outside of the range of the keypool initially.
The indexes and internal-ness of a key is gotten by checking it's key origin data.
Because of this change, we no longer need to wait for IBD to finish before `sethdseed` can work so that check is also removed.
A test case for this is added as well which fails on master.

a8334f7ac39532528c5f8bd3b0eea05aa63e8794 Read and write a checksum for encrypted keys (Andrew Chow)
Pull request description:
Adds a checksum to the encrypted key record in the wallet database so that encrypted keys can be checked for corruption on wallet loading, in the same way that unencrypted keys are. This allows for us to skip the full decryption of keys upon the first unlocking of the wallet in that session as any key corruption will have already been detected. The checksum is just the double SHA256 of the encrypted key and it is appended to the record after the encrypted key itself.
This is backwards compatible as old wallets will be able to read the encrypted key and ignore that there is more data in the stream. Additionally, old wallets will be upgraded upon their first unlocking (so that key decryption is checked before we commit to a checksum of the encrypted key) and a wallet flag set indicating that. The presence of the wallet flag lets us skip the full decryption as if `fDecryptionThoroughlyChecked` were true.
This does mean that the first time an old wallet is unlocked in a new version will take much longer, but subsequent unlocks will be instantaneous. Furthermore, corruption will be detected upon loading rather than on trying to send so wallet corruption will be detected sooner.
Fixes #12423

When a key from an inactive seed is used, generate replacements
to fill a keypool that would have been there.

m_address_type was used for two things:
1. Determine the type of descriptor to generate during
SetupDescriptorGeneration
2. Sanity check during GetNewDestination.
There is no need to have this variable to accomplish those things.
1. Add a argument to SetupDescriptorGeneration indicating the address
type to use
2. Use Descriptor::GetOutputType for the sanity check.
