Pull request description:
All softforks that are active at the tip of mainnet, should also be active from genesis in regtest. Otherwise their rules might not be enforced in user testing, thus making their testing less useful.
To still allow tests to check pre-softfork rules, a runtime argument can change the activation height.

d1e2481274 test: scale amounts in test_doublespend_chain down by factor 10 (Sebastian Falbesoner)
Pull request description:
This PR aims to further increase MiniWallet usage in the functional test feature_rbf.py by using it in the `make_utxo(...)` helper, which is the only part that needs a wallet for most sub-tests. In order to do that, the amounts for the utxos have to be scaled down in two sub-tests first (`test_doublespend_chain` and `test_doublespend_tree`, see first two commits), since we need amounts passed to `make_utxo` than can be funded by only one input. For creating UTXOs with a value of 50 BTC, we'd need to implement a method for consolidating multiple utxos into one first, which seems to be overkill.
Note that after this PR's change, there is only one sub-test left (`test_rpc`) that needs the wallet compiled into bitcoind.

Pull request description:
This PR implements a function to calculate mempool ancestors for a package and enforces ancestor/descendant limits on them as a whole. It reuses a portion of `CalculateMemPoolAncestors()`; there's also a small refactor to move the reused code into a generic helper function. Instead of calculating ancestors and descendants on every single transaction in the package and their ancestors, we use a "worst case" heuristic, treating every transaction in the package as each other's ancestor and descendant. This may overestimate everyone's counts, but is still pretty accurate in the our main package use cases, in which at least one of the transactions in the package is directly related to all the others (e.g. 1 parent + 1 child, multiple parents with 1 child, or chains).
Note on Terminology: While "package" is often used to describe groups of related transactions _within_ the mempool, here, I only use package to mean the group of not-in-mempool transactions we are currently validating.
#### Motivation
It would be a potential DoS vector to allow submission of packages to mempool without a proper guard for mempool ancestors/descendants. In general, the purpose of mempool ancestor/descendant limits is to limit the computational complexity of dealing with families during removals and additions. We want to be able to validate multiple transactions on top of the mempool, but also avoid these scenarios:
- We underestimate the ancestors/descendants during package validation and end up with extremely complex families in our mempool (potentially a DoS vector).
- We expend an unreasonable amount of resources calculating everyone's ancestors and descendants during package validation.

5a1bef60a0 test: refactor: remove binascii from test_framework (Zero-1729)
Pull request description:
This PR continues the work started in PR #22593, regarding using the `bytes` built-in module. In this PR specifically, instances of `binascii`'s methods `hexlify`, `unhexlify`, and `a2b_hex` have been replaced with the build-in `bytes` module's `hex` and `fromhex` methods where appropriate to make bytes <-> hex-string conversions consistent across the functional test files and test_framework.
Additionally, certain changes made are based on the following assumption:
```
bytes.hex(data) == binascii.hexlify(data).decode()
bytes.hex(data).encode() == binascii.hexlify(data)
```
Ran the functional tests to ensure behaviour is still consistent and changes didn't break existing tests.

222290f543 test: Set BIP34Height = 2 for regtest (MarcoFalke)
fac90c55be test: Create all blocks with version 4 or higher (MarcoFalke)
Pull request description:
BIP34 is active on the current tip of mainnet, so all miners must obey it. It would be nice if it also was active in fresh regtest instances from the earliest time possible.
I changed the BIP34 height to `2`, so that the block at height=1 may be used to mine a duplicate coinbase. (Needed to test mainnet behaviour)
This pull is done in two commits:
* test: Create all blocks with version 4 or higher:
Now that BIP34 is activated earlier, we need to create blocks with a higher version number. Just bump it to 4 instead of 2 to avoid having to bump it again later.
* test: Set BIP34Height = 2 for regtest:
This fixes the BIP34 implementation in the tests (to match the one of the Core codebase) and updates the tests where needed

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.

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.

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.

b6c5d1e450 p2p: AddrFetch - don't disconnect on self-announcements (Martin Zumsande)
Pull request description:
AddrFetch connections (old name: oneshots) are intended to be short-lived connections on which we ask a peer for addresses via `getaddr` and disconnect after receiving them.
This is done by disconnecting after receiving the first `addr`. However, it is no longer working as intended, because nowadays, the first `addr` a typical bitcoin core node sends is its self-announcement.
So we'll disconnect before the peer gets a chance to answer our `getaddr`.
I checked that this affects both `-seednode` peers specified manually, and DNS seeds when AddrFetch is used as a fallback if DNS doesn't work for us.
The current behavior of getting peers via AddrFetch when starting with an empty addrman would be to connect to the peer, receive its self-announcement and add it to addrman, disconnect, reconnect to the same peer again as a full outbound (no other addresses in addrman) and then receive more `addr`. This is silly and not in line with AddrFetch peer being intended to be short-lived peers.
Fix this by only disconnecting after receiving an `addr` message of size > 1.
[Edit] As per review discussion, this PR now also adds a timeout after which we disconnect if we haven't received any suitable `addr`, and a functional test.

nodes on the network to relay I2P addresses to help with propagation,
similarly to what we do with Tor addresses.

ACK 7593b06bd1. Code looks correct, tested that functional test suite passes and also that `test/functional/p2p_addrv2_replay.py` fails if I undo changes in `IsRelayable()`.

The constant `MAX_BLOCK_BASE_SIZE` has been removed from the
core implementation years ago due to being confusing and
superfluous, as it is implied by the block weight limit (see
PRs #10618 and #10608). Since there is also no point in
still keeping it in the functional test framework, we switch
to weight-based accounting on the relevant test code parts
and use `MAX_BLOCK_WEIGHT` instead for the block limit
checks.
