fa749fbea3cad64582f76f7a58cfcc0d91a97326 rpc: Replace boost::variant with std::variant for RPCArg.m_fallback (MarcoFalke)
Pull request description:
Now that we can use std::variant from the vanilla standard library, drop the third-party boost variant dependency.
Patch is split out from #20480. A step-by-step replacement is possible because we don't have our own `Variant` wrapper and the source code specifies `boost::variant` explicitly.
I think a step-by-step replacement should be preferred, because it simplifies review.

bf7d6e31b1062ab5f90e14e83c56309f499fa2e9 RPC: getblock: tx fee calculation for verbosity 2 via Undo data (Elliott Jin)
Pull request description:
This change is progress towards #18771 . It adapts the fee calculation part of #16083 and addresses some feedback. The additional "verbosity level 3" features are planned for a future PR.
**Original PR description:**
> Using block undo data (like in #14802) we can now show fee information for each transaction in a block without the need for additional -txindex and/or a ton of costly lookups. For a start we'll add transaction fee information to getblock verbosity level 2. This comes at a negligible speed penalty (<1%).

812baaa1f804a8c848284759c75e5f9d19e942f8 Switch to BIP341's suggested scheme for outputs without script (Pieter Wuille)
Pull request description:
BIP341 suggests using Hash<sub>TapTweak</sub>(pubkey) to derive the tweak in case of key-only outputs. The functional test framework currently uses Hash<sub>TapTweak</sub>(pubkey || 0x00...00) instead. Change this.
There is no technical reason to prefer one over the other, but in case someone looks at it for inspiration, it's better to be consistent with the BIP.

11a32722f09f1d81f34bd09b26248ba99f2e7f07 test: run mempool_resurrect.py even with wallet disabled (Michael Dietz)
Pull request description:
Another functional test rewritten as proposed in #20078
**Request for help:**
`node.gettransaction(txid)` fails for transactions sent with `wallet.send_self_transfer`. Even though the `txid`s look correct, are added to the mempool correctly, and removed from the mempool when a block is mined - all as expected.
However, `node.gettransaction(txid)` throws the error:
```sh

```
Anyone know what's going wrong / can point me in the right direction if I'm making a mistake, or `MiniWallet` needs to be improved for this to work correctly?

e1e7a90d5f0616a46ffadd62a9f1c65406cca6b4 wallettool: Add dump command (Andrew Chow)
Pull request description:
Adds two commands to the `bitcoin-wallet` tool: `dump` and `createfromdump`. These commands will be useful for a wallet storage migration in the future. It is also generally useful to have a storage agnostic dump like this. These commands are similar to BDB's `db_dump` and `db_load` tools. This can also be useful for manual construction of a wallet file for tests.
`dump` outputs every key-value pair from the wallet as comma separated hex. Each key-value pair is on its own line with the key and value in hex separated by a comma. This is output to the file specified by the new `-dumpfile` option.
`createfromdump` takes a file produced by `dump` and creates a new wallet file with exactly the records specified in that file.
A new option `-dumpfile` is added to the wallet tool. When used with `dump`, the records will be written to the specified file. When used with `createfromdump`, the file is read and the key-value pairs constructed from it. `createfromdump` requires `-dumpfile`.
A simple round-trip test is added to the `tool_wallet.py`.

Pull request description:
This is a simple functional test to increase coverage of #19988, checking that txid announcements from txid-relay peers are delayed by TXID_RELAY_DELAY, assuming we have at least another wtxid-relay peer.

Pull request description:
Rationale: expose and promote descriptor wallets in more places; make cli tool more consistent with `createwallet` rpc.
Add `-descriptors` parameter which is off by default. When specified it will create a new descriptors wallet with sqlite backend, which is consistent with `createwallet` rpc.
