313a081b90 [net] Add seed.bitcoin.wiz.biz to DNS seeds (wiz)
Pull request description:
I've created the `seed.bitcoin.wiz.biz` DNS seed for the benefit of the Bitcoin community, and will operate it in accordance with the [Bitcoin DNS seed operator policy](https://github.com/bitcoin/bitcoin/blob/master/doc/dnsseed-policy.md). Since this is my first PR to the Bitcoin Core project, I also ACK the [contributing guidelines](https://github.com/bitcoin/bitcoin/blob/master/CONTRIBUTING.md).
The data for this DNS seed is generated using redundant instances of TheBlueMatt's [dnsseed-rust implementation](https://github.com/TheBlueMatt/dnsseed-rust), which connects to all discoverable Bitcoin nodes to verify their capabilities and speed, and utilizes the full AS-MAP data from my network's BGP tables to select Bitcoin nodes which are fairly distributed across different networks.
As for my qualifications, I currently operate Bitcoin nodes for the [mempool.space](https://mempool.space/) open-source block explorer project (mempool) and the [Bisq Network](https://bisq.network/) open-source P2P trading community (bisq-network). I have 20 years experience as a network engineer, and all of [my Bitcoin nodes](https://bitnodes.io/nodes/?q=AS54415) are hosted on [my own network](https://ipinfo.io/AS54415) across multiple datacenters. For personal references, the current Bitcoin DNS seed operators Emzy and TheBlueMatt can probably vouch for me.
The DNS responses served from this instance are currently served with a TTL of 60 seconds, and the DNS resolvers do not log queries from users. Any inquiries related to the operation of this DNS seed can be sent to <noc@wiz.biz>.
Here is a rough diagram of the `seed.bitcoin.wiz.biz` DNS seed architecture:

-Waiting is important to avoid race conditions,
especially if testing peer info through rpc later.
-Wait for mininodes to be disconnected only, even
though it's more complex, because we may still want
to be connected to test nodes.
-Use peer to refer to mininodes instead of node
because they are not bitcoind nodes.
-Use log.debug for logs that give helpful but
not super necessary information.
-Adhere to style guidelines (newlines, capitalization).

16d4b3fd6d test: mempool.dat compatibility between versions (Ivan Metlushko)
Pull request description:
Rationale: Verify mempool.dat compatibility between versions
The format of mempool.dat has been changed in #18038
The tests verifies the fix made in #18807 and ensures that the file format is compatible between current version and v0.19.1
The test verifies both backward and forward compatibility.
This PR also adds a log when we fail to add a tx loaded from mempool.dat.
It was useful when debugging this test and could be potentially useful to debug other scenarios as well.
Closes#19037

Every `return false` is preceeded by a detailed debug log message to
explain that a disconnect or misbehavior happened. Logging another
generic "FAILED" message seems redundant.
Also, the size of the message and the message type has already been
logged and is thus redundant as well.
Finally, claiming that message processing FAILED seems odd, because the
message was fully processed to the point where it was concluded that the
peer should be either disconnected or marked as misbehaving.

1c6b787e03 [netprocessing] disconnect node that sends filterclear (gzhao408)
Pull request description:
Nodes that don't have bloomfilters turned on (i.e. no `NODE_BLOOM` service) should disconnect peers that send them `filterclear` P2P messages.
Non-bloomfilter nodes already disconnect peers for [`filteradd` and `filterload`](19e919217e/src/net_processing.cpp (L2218)), but #8709 removed `filterclear` so it could be used to reset tx relay. This isn't needed now because using `feefilter` message is much better for this purpose (See #19204).
Also refactors existing disconnect logic for `filteradd` and `filterload` into respective message handlers and removes banning for them.

-Increasing the banscore and/or banning is too harsh,
just disconnecting is enough.
-Return true from ProcessMessage because we already log
receipt of filterclear and disconnect.
-nodes not serving bloomfilters should disconnect peers
that send filterclear, just like filteradd and filterload
-nodes that want to enable/disable txrelay should use
feefilter

Pull request description:
This PR makes `bitcoin_qt.m4` to use `pkg-config` for all hosts and removes non-pkg-config paths from it. This is a step towards the idea which was clear [stated](https://github.com/bitcoin/bitcoin/pull/8314#issue-76644643) by Cory Fields:
> I believe the consensus is to treat Windows like the others and require pkg-config across the board. We can drop all of the non-pkg-config paths, and simply AC_REQUIRE(PKG_PROG_PKG_CONFIG)
There are two unsolved problems with this PR. If depends is built with `DEBUG=1` the `configure` script fails to pickup Qt:
- for macOS host (similar to, but not the same as #16391)
- for Windows host (regression)
The fix is ~on its way~ submitted in #18298 (as a followup).
Also this PR picks some small improvements from #17820.

Pull request description:
This PR touches only the p2p_invalid_messages.py functional test module. There are two main goals accomplished here. First, it fixes the "invalid message size" test, which previously made a message that was invalid for multiple reasons. Second, it refactors the file into a single consistent style. This file appears to have originally had two authors, with different styles and some test duplication.
It should now be easier and quicker to understand this module, anticipating the upcoming [BIP324](https://github.com/bitcoin/bitcoin/pull/18242) and [AltNet](https://github.com/bitcoin/bitcoin/issues/18989) changes.
This should probably go in ahead of #19107, but the two are not strictly related.

The functional test covers eviction protection for peers that have sent us blocks or txns recently, or that have faster pings. I couldn't find a way to test the logic of `CConnman::AttemptToEvictConnection` that is based on netgroup (see #14210 for related discussion)

Pull request description:
This PR adds a few tests that are bloomfilter-related, including behavior for when bloomfilters are turned _off_:
1. Tests p2p message `msg_mempool`: a node that has `peerbloomfilters` enabled should send its mempool (disabled behavior already tested [here](https://github.com/bitcoin/bitcoin/blob/master/test/functional/p2p_mempool.py)).
2. Tests that bloomfilter peers with [`fRelay=False`](https://github.com/bitcoin/bips/blob/master/bip-0037.mediawiki#extensions-to-existing-messages) in the `version` message should not receive any invs until they set the filter. The rest is the same as what’s already tested in `p2p_filter.py`.
3. Tests that peers get disconnected if they send `filterload` or `filteradd` p2p messages to a node with bloom filters disabled.
4. Refactor: renames p2p_mempool.py to p2p_nobloomfilter_messages.py.
5. Fixes race conditions in p2p_filter.py
