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.

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.

Enable functional tests in the ThreadSanitizer (TSan) build job.
This is a follow-up to @MarcoFalke's #14764 which added TSan but for unit tests only.

Remove no longer needed UBSan suppressions (issues fixed). Add documentation.
This PR is the CI-only subset of #17208 (which touches code).
From a fuzzing perspective it would be really nice to be able to run UBSan with as few suppressions as possible :)

Pull request description:
Ensure prevector data is appropriately aligned. Earlier discussion in #17530.
**Edit laanwj**: In contrast to #17530, it does this without increase in size of any of the coin cache data structures (x86_64, clang)
| Struct | (size,align) before | (size,align) after |
| ------------- | ------------- | ------- |
| Coin | 48, 8 | 48, 8 |
| CCoinsCacheEntry | 56, 8 | 56, 8 |
| CScript | 32, 1 | 32, 8 |

958e1a307e streams: Remove unused seek(size_t) (practicalswift)
Pull request description:
Fix broken `streams_vector_reader` test. Remove unused `seek(size_t)`.
Before this change the test `streams_vector_reader` triggered an unintended unsigned integer wraparound. It tried so seek using a negative value in `reader.seek(-6)`.
Changes in this PR:
* Fix broken `VectorReader::seek(size_t)` test case
* Remove unused `seek(size_t)`

> It doesn't support multithreaded validation and there are lot of things that prevent that, which is why I was concerned. Why doesn't the lock on the block index or even cs main prevent concurrency here?
