faadc606c7644f2934de390e261d9d65a81a7592 refactor: Pass const reference instead of pointer to GetBlockScriptFlags (MarcoFalke)
Pull request description:
Now that Taproot is active, it makes sense to enforce its rules on all blocks, even historic ones, regardless of the deployment status.
### Benefits:
(With "script flags" I mean "taproot script verification flags".)
* Script flags are known ahead for all blocks (even blocks not yet created) and do not change. This may benefit static analysis, code review, and development of new script features that build on Taproot.
* Any future bugs introduced in the deployment code won't have any effect on the script flags, as they are independent of deployment.
* Enforcing the taproot rules regardless of the deployment status makes testing easier because invalid blocks after activation are also invalid before activation. So there is no need to differentiate the two cases.
* It gives belt-and-suspenders protection against a practically expensive and theoretically impossible IBD reorg attack where the node is eclipsed. While `nMinimumChainWork` already protects against this, the cost for a few months worth of POW might be lowered until a major version release of Bitcoin Core reaches EOL. The needed work for the attack is the difference between `nMinimumChainWork` and the work at block 709632.
For reference, previously the same was done for P2SH and WITNESS in commit 0a8b7b4b33c9d78574627fc606267e2d8955cd1c.
### Implementation:
I found one block which fails verification with the flags applied, so I added a `TaprootException`, similar to the `BIP16Exception`.
For reference, the debug log:
```
ERROR: ConnectBlock(): CheckInputScripts on b10c007c60e14f9d087e0291d4d0c7869697c6681d979c6639dbd960792b4d41 failed with non-mandatory-script-verify-flag (Witness program was passed an empty witness)

```
Hint for testing, make sure to set `-noassumevalid`.
### Considerations
Obviously this change can lead to consensus splits on the network in light of massive reorgs. Currently the last block before Taproot activation, that is the last block without the Taproot script flags set, is only buried by a few days of POW. However, when and if this patch is included in the next major release, it will be buried by a few months of POW. BIP90 considerations apply when looking at reorgs this large.

This was changed in #22818 from 0 to 1. Since it changes
BLOCK_OPT_WIT of the genesis block, older versions of bitcoin
core would not read regtest directories created with newer versions
without a reindex.

- `m_assumed_chain_state_size` doesn't seem to need to be changed for mainnet.
- No change needed for testnet/signet.

dc10ca346b138d8de88c7bf53b1d7e69cc63e989 net: switch to signet DNS seed (Sjors Provoost)
Pull request description:
I spun up a DNS seed for Signet, source: https://github.com/sipa/bitcoin-seeder/pull/94
If anyone else spins up a DNS seed, let me know in the comment and I'll add it.
Because one DNS seed is not very diverse, this PR leaves two hardcoded nodes just in case (). The one dropped node no longer exists.
Replaces #23000.

fac90c55be478f0323eafa1d560ea2c56f04fb23 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

9c0871977839c28636eff975748182888299cd2b [test] Introduce test logic to query DNS seeds (Amiti Uttarwar)
Pull request description:
This PR adds a DNS seed to the regtest chain params to enable testing the DNS seed querying logic of `CConnman::ThreadDNSAddressSeed` and relevant startup parameters. Adds coverage for the changes in #22013 (and then some).
The main behavioral change to bitcoind is that this PR disallows starting up with conflicting parameters for `-dnsseed` and `-forcednsseed`.
The tests include:
* parameter interactions of different combinations of `-connect`, `-dnsseed` and `-forcednsseed`
* the delay before querying DNS seeds depending on how many addresses are in the addrman
* the behavior of `-forcednsseed`
* skipping DNS querying if we have outbound full relay connections & not block-relay-only connections
Huge props to mzumsande for identifying the timing technique for testing successful connections before running `ThreadDNSAddressSeed` 🙌🏽

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.

Pull request description:
Builds on #21009 and makes progress on remaining items in #17862
Removing `RewindBlockIndex()` in #21009 allows the following:
- removal of tests using `segwitheight=-1` in `p2p_segwit.py`.
- move `test_upgrade_after_activation()` out of `p2p_segwit.py` reducing runtime
- in turn, that allows us to drop support for `-segwitheight=-1`, which is only supported for that test.
- that allows us to always set `NODE_WITNESS` in our local services. The only reason we don't do that is to support `-segwitheight=-1`.
- that in turn allows us to drop all of the `GetLocalServices() & NODE_WITNESS` checks inside `net_processing.cpp`, since our local services would always include `NODE_WITNESS`

invention, which allowed the deployment to still be activated in unit

Pull request description:
Closes #20239 and mitigates my node's problem in #21351.
- Add a few hardcoded seeds for TorV3
- As the [bitcoin-seeder](https://github.com/sipa/bitcoin-seeder) doesn't collect TorV3 addresses yet, I have extracted these from my own node using [a script](https://gist.github.com/laanwj/b3d7b01ef61ce07c2eff0a72a6b90183) and added them manually. This is intended to be a temporary stop gap until 22.0's seeds update.
- Change hardcoded seeds to variable length BIP155 binary format.
- It is stored as a single serialized blob in a byte array, instead of pseudo-IPv6 address slots. This is more flexible and, assuming most of the list is IPv4, more compact.
- Only the (networkID, addr, port) subset (CService). Services and time are construed on the fly as before.
- Change input format for `nodes_*.txt`.
- Drop legacy `0xAABBCCDD` format for IPv4. It is never generated by `makeseeds.py`.
- Stop interpreting lack of port as default port, interpret it as 'no port', to accomodate I2P and other port-less protocols (not handled in this PR). An explicit port is always generated by `makeseeds.py` so in practice this makes no difference right now.
A follow-up to this PR could do the same for I2P.

Maintaining the blockfilterindexes in prune mode is possible and may lead to efficient p2p based rescans of wallets (restore backups, import/sweep keys) beyond the prune height (rescans not part of that PR).

63d4ee1968144cc3d115f92baef95785abf813ac refactor: iterate arrays via C++11 range-based for loops if idx is not needed (Sebastian Falbesoner)
Pull request description:
This refactoring PR picks up the idea of #19626 and replaces all occurences of `sizeof(x)/sizeof(x[0])` (or `sizeof(x)/sizeof(*x)`, respectively) with the now-available C++17 [`std::size`](https://en.cppreference.com/w/cpp/iterator/size) (as [suggested by sipa](https://github.com/bitcoin/bitcoin/pull/19626#issuecomment-666487228)), making the macro `ARRAYLEN` obsolete.
As preparation for this, two other changes are done to eliminate `sizeof(x)/sizeof(x[0])` usage:
* all places where arrays are iterated via an index are changed to use C++11 range-based for loops If the index' only purpose is to access the array element (as [suggested by MarcoFalke](https://github.com/bitcoin/bitcoin/pull/19626#discussion_r463404541)).
* `std::vector` initializations are done via `std::begin` and `std::end` rather than using pointer arithmetic to calculate the end (also [suggested by MarcoFalke](https://github.com/bitcoin/bitcoin/pull/20429#discussion_r567418821)).

Values for mainnet and testnet will be specified in a follow-up PR that can be
scrutinized accordingly. This structure is required for use in snapshot activation
logic.
