dd7b5f46d8 script: fix deprecation warning in makeseeds.py (Jon Atack)
Pull request description:
Seen while reviewing #20237.
1. Fix a deprecation warning in `contrib/seeds/makeseeds.py`
```
makeseeds.py:139: DeprecationWarning: please use dns.resolver.resolve() instead
asn = int([x.to_text() for x in dns.resolver.query('.'.join(
```
- Per https://dnspython.readthedocs.io/en/latest/whatsnew.html, `dns.resolver.query()` was deprecated in `dnspython` version 2.0.0.
- See https://dnspython.readthedocs.io/en/latest/resolver-class.html for more info on the resolver class.
2. Update the `dnspython` dependency installation instructions in `contrib/seeds/README`

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.

- Change regular expression to cover recent versions, as well as
subversions with custom uacomment, and improve readability.
- Vary uptime requirements per network (onions are allowed to have less
uptime, to make sure we get enough of them)
- Add deduplication step (to allow simple concatentation of multiple seeds files).
- Log of number of nodes (per network) after every step.
Flagged by flake8 v3.6.0, as W605, plus a few others identified
incidentally, e.g. 59ffecf66cf4d08c4b431e457b083878d66a3fd6.
Note that r"\n" matches to "\n" under re.match/search.
44407100f broke inserting entries into addrman from static seeds
(as well as dnsseeds which did not support service bits). Static
seeds were already being filtered by UA for 0.13.1+ (ie
NODE_WITNESS), so simply changing the default service bits to
include NODE_WITNESS (and updating docs appropriately) is
sufficient.
For DNS Seeds, we will later fix by falling back to oneshot if a
seed does not support filtering.
Allow for non-8333 nodes to appear in the internal seeds. This will
allow bitcoind to bypas a filter on 8333. This also makes it possible to
use the same tool for e.g. testnet.
As hosts with multiple nodes per IP are likely abusive, add a filter to
remove these (the ASN check will take care of them for IPv4, but not
IPv6 or onion).
- Moved all seed related scripts to contrib/seeds for consistency
- Updated `makeseeds.py` to handle IPv6 and onions, fix regular
expression for recent Bitcoin Core versions
- Fixed a bug in `generate-seeds.py` with regard to IPv6 parsing
