da2bc865d644f6be748c305556bdd02f02d1b161 [wallet] don't create long chains by default (glozow) Pull request description: Default mempool policy doesn't let you have chains longer than 25 transactions. This is locally configurable of course, but it's not really safe to assume that a chain longer than 25 transactions will propagate. Thus, the wallet should probably avoid creating such transactions by default; set `DEFAULT_WALLET_REJECT_LONG_CHAINS` to true.

Motivations for this change are: - To make it easier to see when node and wallet code is being accessed places where it shouldn't be. For example if GUI code is accessing node and wallet internals or if wallet and node code are referencing each other. - To make source code organization clearer ([#15732](https://github.com/bitcoin/bitcoin/issues/15732)), being able to know that `wallet::` code is in `src/wallet/`, `node::` code is in `src/node/`, `init::` code is in `src/init/`, `util::` code is in `src/util/`, etc. Reviewing with `git log -p -n1 -U0 --word-diff-regex=.` can be helpful to verify this is only updating declarations, not changing code.

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. fixes #19856 fixes #20293 ACKs for top commit: laanwj: Code review ACK 3d71d16d1eb4173c70d4c294559fc2365e189856 Tree-SHA512: 03fafd5548ead0c4ffe9ebcc9eb2849f1d2fa7270fda4166419b86877d4e57dcf04460e465fbb9c90b42031f3c05d1b83f1b67a9f82c2a42980825ed1e7b52e6

d8ee8f3cd32bbfefec931724f5798cbb088ceb6f refactor: Make CWalletTx sync state type-safe (Russell Yanofsky) Pull request description: Current `CWalletTx` state representation makes it possible to set inconsistent states that won't be handled correctly by wallet sync code or serialized & deserialized back into the same form. For example, it is possible to call `setConflicted` without setting a conflicting block hash, or `setConfirmed` with no transaction index. And it's possible update individual `m_confirm` and `fInMempool` data fields without setting an overall consistent state that can be serialized and handled correctly. Fix this without changing behavior by using `std::variant`, instead of an enum and collection of fields, to represent sync state, so state tracking code is safer and more legible. This is a first step to fixing state tracking bugs https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Transaction-Conflict-Tracking, by adding an extra margin of safety that can prevent new bugs from being introduced as existing bugs are fixed.

Followup to commit "MOVEONLY: CWallet transaction code out of wallet.cpp/.h" that detaches and renames some CWalletTx methods, making into them into standalone functions or CWallet methods instead. There are no changes in behavior and no code changes that aren't purely mechanical. It just gives spend and receive functions more consistent names and removes the circular dependencies added by the earlier MOVEONLY commit. There are also no comment or documentation changes. Removed comments from transaction.h are just migrated to spend.h, receive.h, and wallet.h.

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).

This is not very user friendly as normalized descriptors shouldn't require and don't involve the private keys except for derivation. We solve this problem by caching the last hardened xpub (which has to be derived at some point when generating the address pool). However the last hardened xpub was not already being cached. We only cached the immediate parent xpub and derived child keys. For example, with a descriptor derivation path of `/84'/0'/0'/0/*`, the parent xpub that is cached is `m/84'/0'/0'/0`, and the child keys of `m/84'/0'/0'/0/i` (note that child keys would not be cached in this case). This parent xpub is not suitable for the normalized descriptor form as we want the key at `m/84'/0'/0'`. So this PR adds another field to `DescriptorCache` to cache the last hardened xpub so that we can use them for normalized descriptors. Since `DescriptorCache` is changing, existing descriptor wallets need to be upgraded to use this new cache. The upgrade will occur in the background either at loading time (if the wallet is not encrypted) or at unlocking time in the same manner that `UpgradeKeyMetadata` operates. It will use a new wallet flag `WALLET_FLAG_LAST_HARDENED_XPUB_CACHED` to indicate whether the descriptor wallet has the last hardened xpub cache. Lastly `listdescriptors` will not require the wallet to be locked and `getaddressinfo`'s `parent_desc` will always be output (assuming the upgrade has occurred).

2021-06-22wallet: Add error message to GetReservedDestinationAndrew Chow
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.
