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.

Following up on #23020 from jamesob with achow101's additional features on top.
Both mentioned that they will be away for the next few weeks, so this is intended to keep review going.
All credit to the jamesob and achow101. See #23020 for the original description and [here](https://github.com/bitcoin/bitcoin/pull/23020#issuecomment-1480603300) for the added features.
I squashed the last commit from https://github.com/achow101/bitcoin/tree/pr23020-direct-bins-gpg-parse into the first commit here.
Fetching and local verification seem to work as intended for me.

In addition to verifying the published releases with the `pub` command,
the verifybinaries script is updated to take a `bin` command where the
user specifies the local files, sums, and sigs to verify.
This commit adds the functionality necessary to transition from
doing binary verification on the basis of a single signature to
requiring a minimum threshold of trusted signatures.
A signature can appear as "good" from GPG output, but it may not come
from an identity the user trusts. We call these "good, untrusted"
signatures.
We report bad signatures but do not necessarily fail in their presence,
since a bad signature might coexist with enough good, trusted signatures
to fulfill our criteria.
If "--import-keys" is enabled, we will prompt the user to
optionally try to retrieve unknown keys. Marking them as trusted locally
is a WIP, but keys which are retrieved successfully and appear on the
builder-keys list will immediately count as being useful towards
fulfilling the threshold.
Logging is improved and an option to output JSON that summarizes the
whole sum signature and binary verification processes has been added.

4b7aec2951 Add mempool tracepoints (virtu)
Pull request description:
This PR adds multiple mempool tracepoints.
| tracepoint | description |
| ------------- | ------------- |
| `mempool:added` | Is called when a transaction enters the mempool |
| `mempool:removed` | ... when a transaction is removed from the mempool |
| `mempool:replaced` | ... when a transaction is replaced in the mempool |
| `mempool:rejected` | ... when a transaction is rejected from entering the mempool |
The tracepoints are further documented in `docs/tracing.md`. Usage is demonstrated in the example script `contrib/tracing/mempool_monitor.py`. Interface tests are provided in `test/functional/interface_usdt_mempool.py`.
The rationale for passing the removal reason as a string instead of numerically is that the benefits of not having to maintain a redundant enum-string mapping seem to outweigh the small cost of string generation. The reject reason is passed as string as well, although in this instance the string does not have to be generated but is readily available.

Tracepoints for added, removed, replaced, and rejected transactions.
The removal reason is passed as string instead of a numeric value, since
the benefits of not having to maintain a redundant enum-string mapping
seem to outweigh the small cost of string generation. The reject reason
is passed as string as well, although here the string does not have to
be generated but is readily available.
So far, tracepoint PRs typically included two demo scripts: a naive
bpftrace script to show raw tracepoint data and a bcc script for a more
refined view. However, as some of the ongoing changes to bpftrace
introduce a certain degree of unreliability (running some of the
existing bpftrace scripts was not possible with standard kernels and
bpftrace packages on latest stable Ubuntu, Debian, and NixOS), this PR
includes only a single bcc script that fuses the functionality of former
bpftrace and bcc scripts.

Pull request description:
Currently the `verify-commits.py` script does not work well with maintainers giving up their commit access. If a key is removed from `trusted-keys`, any commits it signed previously will fail to verify, however keys cannot be kept in the list as it would allow that person to continue to push new commits. Furthermore, the `trusted-keys` used depends on the working tree which `verify-commits.py` itself may be modifying. When the script is run, the `trusted-keys` may be the one that is intended to be used, but the script may change the tree to a different commit with a different `trusted-keys` and use that instead!
To resolve these issues, I've updated `verify-commits.py` to load the `trusted-keys` file and check the keys itself rather than delegating that to `gpg.sh` (which previously read in `trusted-keys`). This avoids the issue with the tree changing.
I've also updated the script so that it stops modifying the tree. It would do this for the clean merge check where it would checkout each individual commit and attempt to reapply the merges, and then checking out the commit given as a cli arg. `git merge-tree` lets us do basically that but without modifying the tree. It will give us the object id for the resulting tree which we can compare against the object id of the tree in the merge commit in question. This also appears to be quite a bit faster.
Lastly I've removed all of the exception commits in `allow-revsig-commits`, `allow-incorrect-sha512-commits`, and `allow-unclean-merge-commits` since all of these predate the commits in `trusted-git-root` and `trusted-sha512-root`. I've also updated the script to skip verification of commits that predate `trusted-git-root`, and skip sha512 verification for those that predate `trusted-sha512-root`.
