Pull request description:
This PR builds on the test refactors extracted into #22306 (first 5 commits).
This PR aims to reduce addr blackholes. When we receive an `addr` message that contains 10 or less addresses, we forward them to 1-2 peers. This is the main technique we use for self advertisements, so sending to peers that wouldn't relay would effectively "blackhole" the trickle. Although we cannot prevent this in a malicious case, we can improve it for the normal, honest cases, and reduce the overall likelihood of occurrence. Two known cases where peers would not participate in addr relay are if they have connected to you as a block-relay-only connection, or if they are a light client.
This implementation defers initialization of `m_addr_known` until it is needed, then uses its presence to decide if the peer is participating in addr relay. For outbound (not block-relay-only) peers, we initialize the filter before sending the initial self announcement when processing their `version` message. For inbound peers, we initialize the filter if/when we get an addr related message (`ADDR`, `ADDRV2`, `GETADDR`). We do NOT initialize the filter based on a `SENDADDRV2` message.
To communicate about these changes beyond bitcoin core & to (try to) ensure that no other software would be disrupted, I have:
- Posted to the [mailing list](https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2021-April/018784.html)
- Researched other open source clients to confirm compatibility, opened issues in all the projects & documented in https://github.com/bitcoin/bitcoin/pull/21528#issuecomment-809906430. Many have confirmed that this change would not be problematic.

Pull request description:
This is a very late follow-up PR to #10618, which removed the constant `MAX_BLOCK_BASE_SIZE` from the core implementation about four years ago (see also #10608 in why it was considered confusing and superfluous).
Since there is also no point in still keeping it in the functional test framework, the PR switches to weight-based accounting on the relevant test code parts and use `MAX_BLOCK_WEIGHT` instead for the block limit checks. To prepare that, the first two commits introduce `get_weight()` helpers for the classes CTransaction and CBlock, respectively.

8a2b58db9e test: fix segwit terminology (s/witness_program/witness_script/) (Sebastian Falbesoner)
Pull request description:
This PR fixes wrong uses of the term "witness program", which according to [BIP141](https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki#Witness_program) is defined as follows:
> A scriptPubKey (or redeemScript as defined in BIP16/P2SH) that consists of a 1-byte push opcode (for 0 to 16) followed by a data push between 2 and 40 bytes gets a new special meaning. The value of the first push is called the "version byte". **The following byte vector pushed is called the "witness program".**
In most cases where "witness program" is used in tests (concerns comments, variable names and in one instance even a function name) what we really want to denote is the "witness script". Thanks to [MarcoFalke for pointing this out in a review comment](https://github.com/bitcoin/bitcoin/pull/22363#discussion_r666794261)!
Some historical background: At the time when the P2P segwit tests were first introduced (commit 330b0f31ee, PR #8149), the term "witness program" was not used consistently in BIP141: https://bitcoin.stackexchange.com/questions/46451/what-is-the-precise-definition-of-witness-program
This was fixed in PR https://github.com/bitcoin/bips/pull/416 later.
So in some way, this PR can be seen as a very late follow-up to the BIP141 fix that also reflects these changes in the tests.

Don't schedule class PeerManagerImpl's background tasks from its
constructor, but instead do that from a separate method,
StartScheduledTasks(), that can be called later at the end of startup,
after other things, such as the active chain, are initialzed.
When starting up with a populated addrman, ThreadDNSAddressSeed adds a delay
during which time the node may be able to connect to some peers. This commit
tests the delay changes based on the number of addresses in the addrman.
Test that passing conflicting parameters for the two causes a startup error.
This logic also impacts -connect, which soft sets -dnsseed, so add a test for
that too.
-dnsseed determines whether we run ThreadDNSAddressSeed and potentially query
the DNS seeds for addresses. -forcednsseed tells the node to force querying the
DNS seeds even if we have sufficient addresses or current connections.
This commit disallows starting up with explicitly conflicting parameters.
When a node is able to properly shutdown, it will persist its block-relay-only
connections to the addrman. On startup, it will attempt to reconnect to these
anchors. Since block-relay-only connections do not participate in ADDR relay,
succesful connections are insufficient to skip querying the DNS seeds.
This test fails prior to the changes in #22013.

This commit introduces a DNS seed to the regest chain params in order to add
coverage to the DNS querying logic.
The first test checks that we do not query DNS seeds if we are able to
succesfully connect to 2 outbound connections. Since we participate in ADDR
relay with those connections, including sending a GETADDR message during the
VERSION handshake, querying the DNS seeds is unnecessary.

84c874794c test: remove unneeded initialization code in feature_rbf.py (Sebastian Falbesoner)
Pull request description:
This PR's goal is to prepare the functional test `feature_rbf.py` for more MiniWallet usage. It first gets rid of unused initialization code (I guess that was needed at times when the nodes were still in IBD at the start of tests?), then makes the MiniWallet instance introduced in #22210 available for all sub-tests, and finally, uses that instance in the first sub-test `test_simple_doublespend`.
Note that the same idea of replacing the `make_utxo` calls with MiniWallet can be also applied to other sub-tests too; this just serves as a first proof-of-concept.

8ca51af1ec test: Disable automatic connections by default (Martin Zumsande)
Pull request description:
A node normally doesn't make automatic connections to peers in the functional tests because neither DNS seeds nor hardcoded peers are available on regtest. However, when random entries are inserted into addrman as part of a functional test (e.g. while testing addr relay), `ThreadOpenConnections` will periodically try to connect to them, resulting in log entries such as:
`[opencon] [net.cpp:400] [ConnectNode] trying connection 18.166.1.1:8333 lastseen=0.0hrs`
I don't think it's desirable that functional tests try to connect to random computers on the internet, aside from the possibility that at some point in time someone out there might actually answer in a way to ruin a test.
This PR fixes this problem by disabling `ThreadOpenConnections` by adding `-connect=0` to the default args, and adding exceptions only when needed for the test to pass.

Leaving the incorrect indentation would be frustrating because:
* Some editor may fix up the whitespace when editing a file, so before
commiting the whitespace changes need to be undone.
* It makes it harder to use clang-format-diff on a change.

This test checks that we only relay addresses with inbound peers who have sent
us an addr related message. Uses a combination of GETADDR and ADDR to verify
when peers are eligible.
Use SetupAddressRelay to only initialize `m_addr_known` as needed. For outbound
peers, we initialize the filter before sending our self announcement (not
applicable for block-relay-only connections). For inbound peers, we initialize
the filter when we get an addr related message (ADDR, ADDRV2, GETADDR).
These changes intend to mitigate address blackholes. Since an inbound peer has
to send us an addr related message to become eligible as a candidate for addr
relay, this should reduce our likelihood of sending them self-announcements.
Use an init param to make clear whether a getaddr message should be sent when
the P2PConnection receives a version message. These changes are in preparation
for upcoming commits that modify the behavior of a bitcoind node and the test
framework.
Idempotent function that initializes m_addr_known for connections that support
address relay (anything other than block-relay-only). Unused until the next
commit.

Pull request description:
`guix-verify` expects `all.SHA256SUMS` but `guix-attest` produces `codesigned.SHA256SUMS`. Since `all.SHA256SUMS` makes more sense (as the file contains all the sha256sums, not just the codesigned ones), `guix-attest` has been changed to output a file of that name.
As a quality of life improvement, `guix-verify` can take `SIGNER` and use the signer's manifest as the base to compare against. This makes it easier to compare a single person's attestations with everyone else's and can make it more obvious when one builder is clearly mismatching with everyone else.
Lastly `release-process.md` is updated with a note about a gotcha that can cause a mismatch in the codesigned attestation.
