faa75fa19335e3e826efa4f2280609a2db34425d Avoid unsigned integer overflow in bitcoin-tx (MarcoFalke)
Pull request description:
While `npos` means "largest unsigned value" and adding `1` to it yields `0`, it may be clearer to just assign `0` to it and only increment otherwise.
This also allows to remove a file-wide suppression for `unsigned-integer-overflow`.

fa7238300c18938cdf627cacfc58d4b81602417f fuzz: Limit fuzzed time to years 2000-2100 (MarcoFalke)
Pull request description:
It doesn't make sense to fuzz times in the past, as Bitcoin Core will refuse to start in the past.
Fix that and also remove a sanitizer suppression, which would be hit in net_processing in `ProcessMessage`:
```cpp
if (addr.nTime <= 100000000 || addr.nTime > nNow + 10 * 60)
addr.nTime = nNow - 5 * 24 * 60 * 60; // <-- Here
```
This changes the format of fuzz inputs. Previously a time value was (de)serialized as 40 bytes, now it is 32 bytes.

* It is file-wide, thus suppressing any other (newly introduced) issues

fadd73037e266edb844f0972e82e9213171ef214 refactor: Remove implicit-integer-sign-change suppressions in validation.cpp (MarcoFalke)
Pull request description:
A file-wide suppression is problematic because it will wave through future violations, potentially bugs.
Fix that by using per-statement casts.

Pull request description:
This is an alternative to #25354 (by my benchmarking, somewhat faster), subsumes #25712, and adds additional test vectors.
It separates the multiple-of-64-bytes-only "core" logic (which becomes simpler) from a layer around which performs caching/slicing to support arbitrary byte amounts. Both have their uses (in particular, the MuHash3072 code can benefit from multiple-of-64-bytes assumptions), plus the separation results in more readable code. Also, since FastRandomContext effectively had its own (more naive) caching on top of ChaCha20, that can be dropped in favor of ChaCha20's new built-in caching.
I thought about rebasing #25712 on top of this, but the changes before are fairly extensive, so redid it instead.

fa6c114ae604571435e8c4d25906a8b6d5b9984c test: Add sanitizer suppressions for AMD EPYC CPUs (MarcoFalke)
Pull request description:
Currently the ci system only runs on intel cpus (and some arm devices), but it won't run on CPUs `Using the 'shani(1way,2way)' SHA256 implementation` (excerpt from debug log).
For reference, google cloud CPUs (which is what Cirrus CI uses) print `Using the 'sse4(1way),sse41(4way),avx2(8way)' SHA256 implementation`
The traceback I got:

Remove no longer needed UBSan suppression.
The float divide-by-zero in `validation.cpp` was fixed by instagibbs in ec30a79f1c430cc7fbda37e5d747b0b31b262fa5 (#15283).

5e146022daa4336de94447e5b8e5418296286927 wallet: fix scanning progress calculation for single block range (Sebastian Falbesoner)
Pull request description:
If the blockchain is rescanned for a single block (i.e. start and stop hashes are equal, and with that also the estimated start/stop verification progress values) the progress calculation could lead to a NaN value caused by a division by zero (0.0/0.0), resulting in an invalid JSON result for the `getwalletinfo` RPC. This PR fixes this behaviour by setting the progress to zero in that special case. Fixes#20297.
The behaviour can easily be reproduced by continuously running single block rescans in an endless loop, e.g. via
```bash
#!/bin/bash
while true
do
bitcoin-cli rescanblockchain $(bitcoin-cli getblockcount)
done
```
and at the same time perform some `getwalletinfo` RPCs.
On the master branch, this leads to frequent invalid responses (tested on mainchain):
```
$ bitcoin-cli getwalletinfo
error: couldn't parse reply from server
$ curl --user `cat ~/.bitcoin/.cookie` --data-binary '{"jsonrpc": "1.0", "id": "curltest", "method": "getwalletinfo", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:8332/
{"result":{"walletname":"","walletversion":169900,"format":"bdb","balance":0.00000000,"unconfirmed_balance":0.00000000,"immature_balance":0.00000000,"txcount":0,"keypoololdest":1603677276,"keypoolsize":1000,"hdseedid":"3196e33ecb47c7130e6ca60f2f895f9259860dca","keypoolsize_hd_internal":1000,"paytxfee":0.00000000,"private_keys_enabled":true,"avoid_reuse":false,"scanning":{"duration":0,"progress":},"descriptors":false},"error":null,"id":"curltest"}
```
(note that missing value for "progress" in the JSON result).
On the PR branch, the behaviour doesn't occur anymore.
