Since the original fix was set to be a "reasonable" transaction
to reduce allocations and the true motivation later revealed,
it makes sense to relax this check to something more principled.
There are more exotic transaction patterns that could take advantage
of a relaxed requirement, such as 1 input, 1 output OP_RETURN to burn
a utxo to fees for CPFP purposes when change isn't practical.
Two changes could be accomplished:
1) Anything not 64 bytes could be allowed
2) Anything above 64 bytes could be allowed
In the Great Consensus Cleanup, suggestion (2) was the route taken.
It would not allow an "empty" OP_RETURN
but would reduce the required padding from 22 bytes to 5.
The functional test is also modified to test the actual case
we care about: 64 bytes

e68d380797 rpc: remove unneeded RPCTypeCheckArgument checks (furszy)
55566630c6 rpc: treat univalue type check error as RPC_TYPE_ERROR, not RPC_MISC_ERROR (furszy)
Pull request description:
Same rationale as #26039, tackling another angle of the problem.
#### Context
We have the same univalue type error checking code spread/duplicated few times:
`RPCTypeCheckObj`, `RPCTypeCheckArgument`, `UniValue::checkType`.
In the first two functions, we are properly returning an `RPC_TYPE_ERROR` while in `UniValue::checkType`
we are throwing an `std::runtime_error` which is caught by the RPC server request handler, who invalidly
treats it as `RPC_MISC_ERROR` (which is a generic error return code that provides no information to the user).
#### Proposed Changes
Throw a custom exception from `Univalue::checkType` (instead of a plain
`std::runtime_error`) and catch it on the RPC server request handler.
So we properly return `RPC_TYPE_ERROR` (-3) on every arg type error and
not the general `RPC_MISC_ERROR` (-1).
This will allow us to remove all the `RPCTypeCheckArgument` calls. As them are redundant since #25629.

68209a7b5c rpc: make addpeeraddress work with cjdns addresses (Martin Zumsande)
a8a9ed67cc init: Abort if i2p/cjdns are chosen via -onlynet but unreachable (Martin Zumsande)
Pull request description:
If the networks i2p / cjdns are chosen via `-onlynet` but the user forgot to provide `-i2psam` / `-cjdnsreachable`, no outbound connections will be made - it would be nice to inform the user about that.
The solution proposed here mimics existing behavior for `-onlynet=onion` and non-specified `-onion`/`-proxy` where we already abort with an InitError - if reviewers would prefer to just print a warning, please say so.
The second commit adds CJDNS support to the debug-only `addpeeraddress` RPC allowing to add CJDNS addresses to addrman for testing and debug purposes. (if `-cjdnsreachable=1`)

b00fc44ca5 test: add coverage for 'add_inputs' dynamic default value (furszy)
ddbcfdf3d0 RPC: bugfix, 'add_inputs' default value is true unless 'inputs' are provided (furszy)
Pull request description:
This bugfix was meant to be in #25685, but decoupled it to try to make it part of 24.0 release.
It's a truly misleading functionality.
This PR doesn't change behavior in any way. Just fixes two invalid RPC help messages and adds test
coverage for the current behavior.
#### Description
In both RPC commands `send()` and `walletcreatefundedpsbt` the help message says
that `add_inputs` default value is false when it's actually dynamically set by the following statement:
```c++
coin_control.m_allow_other_inputs = rawTx.vin.size() == 0;
```
Which means that, by default, `add_inputs` is true unless there is any pre-set input, in which
case, the default is false.

00eeb31c76 scripted-diff: rename CChainState -> Chainstate (James O'Beirne)
Pull request description:
Alright alright alright, I know: we hate refactors. We especially hate cosmetic refactors.
Nobody knows better than I that changing broad swaths of code out from under our already-abused collaborators, only to send a cascade of rebase bankruptcies, is annoying at best and sadistic at worst. And for a rename! The indignation!
But just for a second, imagine yourself. Programming `bitcoin/bitcoin`, on a sandy beach beneath a lapis lazuli sky. You go to type the name of what is probably the most commonly used data structure in the codebase, and you *only hit shift once*.
What could you do in such a world? You could do anything. [The only limit is yourself.](https://zombo.com/)

So maybe you like the idea of this patch but really don't want to deal with rebasing. You're in luck!
Here're the commands that will bail you out of rebase bankruptcy:
```sh
git rebase -i $(git merge-base HEAD master) \
-x 'sed -i "s/CChainState/Chainstate/g" $(git ls-files | grep -E ".*\.(py|cpp|h)$") && git commit --amend --no-edit'
# <commit changed?>
git add -u && git rebase --continue
```

2186608172 test: apply fixed feerate to avoid variable dynamic fees (stickies-v)
Pull request description:
Without specifying a feerate, we let the wallet decide on an appropriate feerate, which can be influenced by various factors
such as what's in the mempool. Since wallet_groups.py fails when feerates are unstable, we should use a fixed feerate across all nodes. The assumed feerate was 20 sats/vbyte, so this PR adopts that.
Closes#25940. I'm not 100% sure, but I think the increased tx relay speed introduced by #25865 caused the transactions to more quickly and often enter the other nodes' mempools, affecting their feerate calculation done in [`wallet:GetMinimumFeeRate()`](ea67232cdb/src/wallet/fees.cpp (L68-L72)) and thus deviating slightly from the expected 20 sats/vbyte.
Ran `wallet_groups.py` over 400 times without failure.

385f5a4c3f p2p: Don't query DNS seeds when both IPv4 and IPv6 are unreachable (Martin Zumsande)
91f0a7fbb7 p2p: add only reachable addresses to addrman (Martin Zumsande)
Pull request description:
Currently, `-onlynet` does not work well in connection with initial peer discovery, because DNS seeds only resolve to IPv6 and IPv4 adresses:
With `-onlynet=i2p`, we would load clearnet addresses from DNS seeds into addrman, be content our addrman isn't empty so we don't try to query hardcoded seeds (although these exist for i2p!), and never attempt to make an automatic outbound connection.
With `-onlynet=onion` and `-proxy` set, we wouldn't load addresses via DNS, but will make AddrFetch connections (through a tor exit node) to a random clearnet peer the DNS seed resolves to (see https://github.com/bitcoin/bitcoin/issues/6808#issuecomment-147652505), thus breaching the `-onlynet` preference of the user - this has been reported in the two issues listed below.
This PR proposes two changes:
1.) Don't load addresses that are unreachable (so that we wouldn't connect to them) into addrman. This is already the case for addresses received via p2p addr messages, this PR implements the same for addresses received from DNS seeds and fixed seeds. This means that in the case of `-onlynet=onion`, we wouldn't load fixed seed IPv4 addresses into addrman, only the onion ones.
2.) Skip trying the DNS seeds if neither IPv4 nor IPv6 are reachable and move directly to adding the hardcoded seeds from networks we can connect to. This is done by soft-setting `-dnsseed` to 0 in this case, unless `-dnsseed=1` was explicitly specified, in which case we abort with an `InitError`.

This happens, for example, if the user specified -onlynet=onion or
-onlynet=i2p. DNS seeds only resolve to IPv4 / IPv6 addresses,
making their answers useless to us, since we don't want to make
connections to these.
If, within the DNS seed thread, we'd instead do fallback AddrFetch
connections to one of the clearnet addresses the DNS seed resolves to,
we might get usable addresses from other networks
if lucky, but would be violating our -onlynet user preference
in doing so.
Therefore, in this case it is better to rely on fixed seeds for networks we
want to connect to.

3405f3eed5 test: Test that an unconfirmed not-in-mempool chain is rebroadcast (Andrew Chow)
10d91c5abe wallet: Deduplicate Resend and ReacceptWalletTransactions (Andrew Chow)
Pull request description:
Currently `ResendWalletTransactions` (used for normal rebroadcasts) will attempt to rebroadcast all of the transactions in the wallet in the order they are stored in `mapWallet`. This ends up being random as `mapWallet` is a `std::unordered_map`. However `ReacceptWalletTransactions` (used for adding to the mempool on loading) first sorts the txs by wallet insertion order, then submits them. The result is that `ResendWalletTranactions` will fail to rebroadcast child transactions if their txids happen to be lexicographically less than their parent's txid. This PR resolves this issue by combining `ReacceptWalletTransactions` and `ResendWalletTransactions` into a new `ResubmitWalletTransactions` so that the iteration code and basic checks are shared.
A test has also been added that checks that such transaction chains are rebroadcast correctly.
