Pull request description:
Update chainparams pre `25.x` branch off.
Co-Author in the commits as a PR (#27223) had previously been opened too-early to do the same.
Note: Remember that some variance is expected in the `m_assumed_*` sizes.

3cc989da5c Fix checking bad dns seeds without casting (Yusuf Sahin HAMZA)
Pull request description:
- Since seed lines comes with `str` type, comparing `good` column directly with **0** (`int` type) in the if statement was not working at all. This is fixed by casting `int` type to the values in the `good` column of seeds text file.
- Lines that starts with comment in the seeds text file are now ignored.
- If statement for checking bad seeds are moved to the top of the `parseline` function as if a seed is bad; there is no point of going forward from there.
Since this bug-fix eliminates bad seeds over **550k** in the first place, in my case; particular job for parsing all seeds speed is up by **600%** and whole script's speed is up by **%30**.
Note that **stats** in the terminal are not going to include bad seeds after this fix, which would be the same if this bug were never there before.

1c07500dbb contrib: make DNS seeds file an argument in CLI (brunoerg)
Pull request description:
Instead of using `makeseeds.py` this way:
```sh
python3 makeseeds.py -a asmap-filled.dat < seeds_main.txt > nodes_main.txt
```
We could use the DNS seeds file as an argument since it is a required one. It improves the way the script handles it when that file is missing as well as makes this script more friendly.
E.g:
```sh
python3 makeseeds.py -a asmap-filled.dat -s seeds_main.txt > nodes_main.txt
```

2ef33e936e contrib: update testnet torv3 hardcoded seeds (Jon Atack)
Pull request description:
As a follow-up to https://github.com/bitcoin/bitcoin/issues/13550 and #22060, replace the mostly unreachable testnet torv3 hardcoded seeds from v0.22 with new ones that are consistently reachable recently and that have service bit 1 set.
This needs to be done before v24.0 to make sure onion-only testnet nodes can still connect to the network.
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
- Re-compile and create a new testnet node with `bitcoind -testnet -dnsseed=0 -onlynet=onion -proxy=127.0.0.1:9050` (or delete `~/.bitcoin/testnet3/peers.dat` and launch bitcoind with `-testnet -dnsseed=0`). Make sure there are no `addnode=` in your `bitcoin.conf`. The debug log should print "Adding fixed seeds". Check if the node is able to connect to the network and get blocks with for ex. `watch -t ./src/bitcoin-cli -testnet -rpcwait -netinfo 4`
- Check the addrman contains the seeds by running for ex. `bitcoin-cli -rpcwait -testnet getnodeaddresses 0 onion | jq -r '.[] | (.address + ":" + (.port|tostring) + " " + (.services|tostring))' | sort`
- Check if the addresses are connectable, for ex. with this python script by laanwj:
```python3
#!/usr/bin/env python3
import pprint
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):
pprint.pprint(line)
subprocess.call(["nc", "-v", "-x", "127.0.0.1:9050", "-z"] + line.split(':'))
```

Add an argument `-a` to provide a asmap file to do the IP to ASN
lookups.
This speeds up the script greatly, and makes the output deterministic.
Also removes the dependency on `dns.lookup`.
I've annotated the output with ASxxxx comments to provide a way to
verify the functionality.
For now I've added instructions in README.md to download and use the
`demo.map` from the asmap repository. When we have some other mechanism
for distributing asmap files we could switch to that.
This continues #24824. I've removed all the fallbacks and extra
complexity, as everyone will be using the same instructions anyway.

I have some qualms with maintaining a suspicious hosts list as part as
the repository. But also, it's stale and irrelevant. I've checked the
entire list and none of them is connectable. Only one still appars in
`nodes_main.txt` but with low uptime and an old subversion string so it
wouldn't be picked in the first place.
Documentation:
- Use https URL for bitcoin.sipa.be (http sends a redirect, fooling
curl).
- Add explicit step to add manual seeds.
Code:
- Change PATTERN_ONION to v3 (effectively means that the no onion hosts
are delivered).
- Add versions to PATTERN_AGENT filter.
- Print specific message on resolve exception.
An IPv6 address from fc00::/8 could be either from the CJDNS network or
from a private-unroutable-reserved segment of IPv6. A seed node with
such an address must be from the CJDNS network, otherwise other peers
will not be able to connect to it.

e1c582cbaa contrib: makeseeds: Read suspicious hosts from a file instead of hardcoding (Sanjay K)
Pull request description:
referring to: https://github.com/bitcoin/bitcoin/issues/17020
good first issue: reading SUSPICIOUS_HOSTS from a file.
I haven't changed the base hosts that were included in the original source, just made it readable from a file.
