6fe0516858 contrib: add torv3 seed nodes for testnet, drop v2 ones (Jon Atack)
Pull request description:
Replace the ancient (2015) Tor V2 hardcoded seeds with new Tor V3 ones. This needs to be done before 0.22 to make sure onion-only testnet nodes can still connect to the network. Continues #21560.
Ways to test:
- Re-generate ` src/chainparamsseeds.h` with `cd contrib/seeds && python3 generate-seeds.py . > ../../src/chainparamsseeds.h`, check if git tree stays the same.
- Create a new testnet node with `bitcoind -testnet -onlynet=onion -proxy=127.0.0.1:9050` (or delete `~/.bitcoin/testnet3/peers.dat`), check if it is able to connect to the network and get blocks.
- Check if the addresses are connectable for ex.:
```python3
#!/usr/bin/env python3
import subprocess
with open('contrib/seeds/nodes_test.txt') as f:
for line in (line for line in (line.rstrip().split('#', 1)[0] for line in f) if line):
subprocess.call(["nc", "-v", "-x", "127.0.0.1:9050", "-z"] + line.split(':'))
```

Pull request description:

The change in the `src/Makefile.qt.include` file does not justify submitting this PR into the main repo, IMHO.

e6fe1c37d0 rpc: Improve avoidpartialspends and avoid_reuse documentation (Fabian Jahr)
8f073076b1 wallet: Increase OUTPUT_GROUP_MAX_ENTRIES to 100 (Fabian Jahr)
Pull request description:
Follow-up to #17824.
This increases OUTPUT_GROUP_MAX_ENTRIES to 100 which means that OutputGroups will now be up to 100 outputs large, up from previously 10. The main motivation for this change is that during the PR review club on #17824 [several participants signaled](https://bitcoincore.reviews/17824.html#l-339) that 100 might be a better value here.
I think fees should be manageable for users but more importantly, users should know what they can expect when using the wallet with this configuration, so I also tried to clarify the documentation on `-avoidpartialspends` and `avoid_reuse` a bit. If there are other additional ways how or docs where users can be made aware of the potential consequences of using these parameters, please let me know. Another small upside is that [there seem to be a high number of batching transactions with 100 and 200 inputs](https://miro.medium.com/max/3628/1*sZ5eaBSbsJsHx-J9iztq2g.png)([source](https://medium.com/@hasufly/an-analysis-of-batching-in-bitcoin-9bdf81a394e0)) giving these transactions a bit of a larger anonymity set, although that is probably a very weak argument.

e40224d0c7 Remove unused float serialization (MarcoFalke)
Pull request description:
Based on #21981.
This adds a software-based platform-independent float/double encoder/decoder (platform independent in the sense that it only uses arithmetic and library calls, but never inspects the binary representation). This should strengthen our guarantee that encoded float/double values are portable across platforms. It then removes the functionality to serialize doubles from serialize.h, and replaces its only (non-test) use for fee estimation data serialization with the software encoder.
At least on x86/ARM, the only difference should be how certain NaN values are encoded/decoded (but not *whether* they are NaN or not).
It comes with tests that verify on is_iec559 platforms (which are the only ones we support, at least for now) that the serialized bytes exactly match the binary representation of floats in memory (for non-NaN).

Changes `KnapsackSolver` to use effective values instead of just the nominal txout value. Since fees are taken into account during the selection itself, we finally get rid of the `CreateTransaction` loop as well as a few other things that only were only necessary because of that loop.
This should not change coin selection behavior at all (except maybe remove weird edge cases that were caused by the loop). In order to keep behavior the same, `KnapsackSolver` will select outputs with a negative effective value (as it did before).

c0385f10a1 Remove -feefilter option (amadeuszpawlik)
Pull request description:
net: Remove -feefilter option, as it is debug only and isn't used in any tests. Checking this option for every peer on every iteration of the message handler is unnecessary, as described in #21545.
refactor: Move feefilter logic out into a separate `MaybeSendFeefilter(...)` function to improve readability of the already long `SendMessages(...)`. fixes #21545
The configuration option `-feefilter` has been added in 9e072a6e66: _"Implement "feefilter" P2P message"_
According to the [BIP133](https://github.com/bitcoin/bips/blob/master/bip-0133.mediawiki), turning the fee filter off was ment for:
> [...] a node [...] using prioritisetransaction to accept transactions whose actual fee rates might fall below the node's mempool min fee [in order to] disable the fee filter to make sure it is exposed to all possible txid's
`-feefilter` was subsequently set as debug only in #8150, with the motivation that the help message was too difficult to translate.

fe3d17df04 net: ignore block-relay-only peers when skipping DNS seed (Anthony Towns)
Pull request description:
Since #17428 bitcoind will attempt to reconnect to two block-relay-only anchors before doing any other outbound connections. When determining whether to use DNS seeds, it will currently see these two peers and decide "we're connected to the p2p network, so no need to lookup DNS" -- but block-relay-only peers don't do address relay, so if your address book is full of invalid addresses (apart from your anchors) this behaviour will prevent you from recovering from that situation.
This patch changes it so that it only skips use of DNS seeds when there are two full-outbound peers, not just block-relay-only peers.

fafd121026 refactor: Make CFeeRate constructor architecture-independent (MarcoFalke)
Pull request description:
Currently the constructor is architecture dependent. This is confusing for several reasons:
* It is impossible to create a transaction larger than the max value of `uint32_t`, so a 64-bit `size_t` is not needed
* Policy (and consensus) code should be arch-independent
* The current code will print spurious compile errors when compiled on 32-bit systems:
```
policy/feerate.cpp:23:22: warning: result of comparison of constant 9223372036854775807 with expression of type 'size_t' (aka 'unsigned int') is always true [-Wtautological-constant-out-of-range-compare]
assert(nBytes_ <= uint64_t(std::numeric_limits<int64_t>::max()));
```
Fix all issues by making it arch-independent. Also, fix `{}` style according to dev notes.

Pull request description:
This PR is a follow up PR to #21244. The PR attempts to move us an inch towards the [goal](https://github.com/bitcoin/bitcoin/pull/21244#discussion_r615307465) by removing `GetDataDir(net_specific)` and replacing it by `gArgs.GetDataDir(net_specific)` calls.
The approach of this PR attempts to be similar to the one chosen in "De-globalize ChainstateManager" (#20158). The goal is to pass `ArgsManager` to functions (or ideally to have `ArgsManager` as a member of a class where needed; inspiration from here: #21789) instead of having it as a global variable (i.e. `gArgs`).
**Notes:**
* First commit makes `m_cached_blocks_path` `mutable` as was suggested [here](https://github.com/bitcoin/bitcoin/pull/21244#discussion_r615274095) but not fully applied in #21244. (`m_cached_datadir_path` and `m_cached_network_datadir_path` were marked as `mutable` in #21244) This commit can be in a separate PR too.
* Other commits deal with removing of `GetDataDir(net_specific)` function.
* This was originally part of #21244 but it was [left]((https://github.com/bitcoin/bitcoin/pull/21244#pullrequestreview-633779754)) for a follow up PR.
* I think that the proposed changes show nicely where there is reliance on `gArgs` which is IMO a good thing.
If you know about a better approach how to do this, please share it here.

fad0867d6a Cleanup -includeconf error message (MarcoFalke)
fa9f711c37 Fix crash when parsing command line with -noincludeconf=0 (MarcoFalke)
Pull request description:
The error message has several issues:
* It may crash instead of cleanly shutting down, when `-noincludeconf=0` is passed
* It doesn't quote the value
* It includes an erroneous trailing `\n`
* It is redundantly mentioning `"-includeconf cannot be used from commandline;"` several times, when once should be more than sufficient
Fix all issues by:
* Replacing `get_str()` with `write()` to fix the crash and quoting issue
* Remove the `\n` and only print the first value to fix the other issues
