66d012ad7f test: RPC: getblock fee calculations (Elliott Jin)
bf7d6e31b1 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%).

812baaa1f8 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.

11a32722f0 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?

a88c320041 wallettool: Add createfromdump command (Andrew Chow)
e1e7a90d5f 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`.

fa13e1b0c5 build: Add option --enable-danger-fuzz-link-all (MarcoFalke)
44444ba759 fuzz: Link all targets once (MarcoFalke)
Pull request description:
Currently the linker is invoked more than 150 times when compiling with `--enable-fuzz`. This is problematic for several reasons:
* It wastes disk space north of 20 GB, as all libraries and sanitizers are linked more than 150 times
* It wastes CPU time, as the link step can practically not be cached (similar to ccache for object files)
* It makes it a blocker to compile the fuzz tests by default for non-fuzz builds #19388, for the aforementioned reasons
* The build file is several thousand lines of code, without doing anything meaningful except listing each fuzz target in a highly verbose manner
* It makes writing new fuzz tests unnecessarily hard, as build system knowledge is required; Compare that to boost unit tests, which can be added by simply editing an existing cpp file
* It encourages fuzz tests that re-use the `buffer` or assume the `buffer` to be concatenations of seeds, which increases complexity of seeds and complexity for the fuzz engine to explore; Thus reducing the effectiveness of the affected fuzz targets

Test coverage is also extended in this commit to:
Ensure that another transaction in the mempool is not evicted
when other transactions expire. Note: this other transaction does
not have any ancestors in the mempool that expired. Otherwise it
would be evicted from the mempool, and we already test this case.
For each address to be relayed we "randomly" pick 2 nodes to send the

343dc4760f test: add test for high-bandwidth mode states in getpeerinfo (Sebastian Falbesoner)

a7ed00f8bb rpc: expose high-bandwidth mode states via getpeerinfo (Sebastian Falbesoner)

Pull request description:
Fixes#19676, "_For every peer expose through getpeerinfo RPC whether or not we selected them as HB peers, and whether or not they selected us as HB peers._" See [BIP152](https://github.com/bitcoin/bips/blob/master/bip-0152.mediawiki), in particular the [protocol flow diagram](https://github.com/bitcoin/bips/raw/master/bip-0152/protocol-flow.png). The newly introduced states are changed on the following places in the code:
* on reception of a `SENDCMPCT` message with valid version, the field `m_highbandwidth_from` is changed depending on the first integer parameter in the message (1=high bandwidth, 0=low bandwidth), i.e. it just mirrors the field `CNodeState.fPreferHeaderAndIDs`.
* after adding a `SENDCMPCT` message to the send queue, the field `m_highbandwidth_to` is changed depending on how the first integer parameter is set (same as above)
Note that after receiving `VERACK`, the node also sends `SENDCMPCT`, but that is only to announce the preferred version and never selects high-bandwidth mode, hence there is no need to change the state variables there, which are initialized to `false` anyways.

fa40168ab3 Remove unused bits from service flags enum (MarcoFalke)
Pull request description:
Remove service bits that haven't been observed on the active network for years and won't ever be observed on the network with this meaning. Keeping this dead assignment in our source code forever doesn't add any value.
I somehow forgot to do this in commit fa0d0ff6e1.
