faa9a74c9e test: Fail wait_until early if connection is lost (MarcoFalke)
Pull request description:
Calling `minonode.wait_until` needs a connection to make progress (e.g. waiting for an inv), unless the mininode waits for the initial connection or for a disconnection. So for test development and failure debugging, fail early in all `wait_until`, unless opted out.

Pull request description:
This is a very simple code change with a big p2p privacy benefit.
It’s currently trivial to scrape any reachable node’s AddrMan (a database of all nodes known to them along with the timestamps).
We do have a limit of one GETADDR per connection, but a spy can disconnect and reconnect even from the same IP, and send GETADDR again and again.
Since we respond with 1,000 random records at most, depending on the AddrMan size it takes probably up to 100 requests for an spy to make sure they scraped (almost) everything.
I even have a script for that. It is totally doable within couple minutes.
Then, with some extra protocol knowledge a spy can infer the direct peers of the victim, and other topological stuff.
I suggest to cache responses to GETADDR on a daily basis, so that an attacker gets at most 1,000 records per day, and can’t track the changes in real time. I will be following up with more improvements to addr relay privacy, but this one alone is a very effective. And simple!
I doubt any of the real software does *reconnect to get new addrs from a given peer*, so we shouldn’t be cutting anyone.
I also believe it doesn’t have any negative implications on the overall topology quality. And the records being “outdated” for at most a day doesn’t break any honest assumptions either.

82dee87933 test: test decodepsbt fee calculation (count input value only once per UTXO) (Sebastian Falbesoner)
Pull request description:
Fixes#19523, adding a simple test to `rpc_psbt.py` that checks that the decodepsbt fee matches the one given by the wallet (`walletcreatefundedpsbt`). This is in particular important for PSBTs with segwit inputs that have both a witness- and a non-witness-UTXO type set.

Pull request description:
From #19580
This PR changes comments to clarify the intended usage of `message_count` and `last_message`. Additionally it changes the only usage of `message_count` to use `last_message` instead, bringing the code into alignment with the intended usage.
Note: Now `message_count` is completely unused. However, it is ready to be used (i.e. the supporting code works) and likely will be used in some test in the future.

65fb8807ac Combine BerkeleyEnvironment::Verify into BerkeleyDatabase::Verify (Andrew Chow)
Pull request description:
`BerkeleyBatch` and `BerkeleyDatabase` are kind of messy. The goal of this is to clean up them up so that they are logically separated.
`BerkeleyBatch` currently handles the creation of the `BerkeleyDatabase`'s `Db` handle. This is instead moved into `BerkeleyDatabase` and is called by `BerkeleyBatch`.
Instead of having `BerkeleyEnvironment` track each database's usage, have `BerkeleyDatabase` track this usage itself with the `m_refcount` variable that is present in `WalletDatabase`.
Lastly, instead of having each `BerkeleyEnvironment` store the fileids of the databases open in it, have a global `g_fileids` to track those fileids. We were already checking fileid uniqueness globally (by checking the fileids in every environment when opening a database) so it's cleaner to do this with a global variable.
All of these changes allow us to make `BerkeleyBatch` and `BerkeleyDatabase` no longer be friend classes.

Pull request description:
Using txids (a transaction's hash, without witness) for transaction relay is problematic, post-segwit -- if a peer gives us a segwit transaction that fails policy checks, it could be because the txid associated with the transaction is definitely unacceptable to our node (regardless of the witness), or it could be that the transaction was malleated and with a different witness, the txid could be accepted to our mempool.
We have a bloom filter of recently rejected transactions, whose purpose is to help us avoid redownloading and revalidating transactions that fail to be accepted, but because of this potential for witness malleability to interfere with relay of valid transactions, we do not use the filter for segwit transactions. This issue is discussed at some length in #8279. The effect of this is that whenever a segwit transaction that fails policy checks is relayed, a node would download that transaction from every peer announcing it, because it has no way presently to cache failure. Historically this hasn't been a big problem, but if/when policy for accepting segwit transactions were to change (eg taproot, or any other change), we could expect older nodes talking to newer nodes to be wasting bandwidth because of this.
As discussed in that issue, switching to wtxid-based relay solves this problem -- by using an identifier for a transaction that commits to all the data in our relay protocol, we can be certain if a transaction that a peer is announcing is one that we've already tried to process, or if it's something new. This PR introduces support for wtxid-based relay with peers that support it (and remains backwards compatible with peers that use txids for relay, of course).
Apart from code correctness, one issue to be aware of is that by downloading from old and new peers alike, we should expect there to be some bandwidth wasted, because sometimes we might download the same transaction via txid-relay as well as wtxid-relay. The last commit in this PR implements a heuristic I want to analyze, which is to just delay relay from txid-relay peers by 2 seconds, if we have at least 1 wtxid-based peer. I've just started running a couple nodes with this heuristic so I can measure how well it works, but I'm open to other ideas for minimizing that issue. In the long run, I think this will be essentially a non-issue, so I don't think it's too big a concern, we just need to bite the bullet and deal with it during upgrade.
Finally, this proposal would need a simple BIP describing the changes, which I haven't yet drafted. However, review and testing of this code in the interim would be welcome.
To do items:
- [x] Write BIP explaining the spec here (1 new p2p message for negotiating wtxid-based relay, along with a new INV type)
- [ ] Measure and evaluate a heuristic for minimizing how often a node downloads the same transaction twice, when connected to old and new nodes.

Using both txid and wtxid-based relay with peers means that we could sometimes
download the same transaction twice, if announced via two different hashes from
different peers.
Use a heuristic of delaying txid-peer-getdata requests by 2 seconds, if we have
at least one wtxid-based peer.
This adds a field to CNodeState that tracks whether to relay transactions with
that peer via wtxid, instead of txid. As of this commit the field will always
be false, but in a later commit we will add a way to negotiate turning this on
via p2p messages exchanged with the peer.

a66a7a1a70 walletdb: don't reinitialize desc cache with multiple cache entries (Andrew Chow)
Pull request description:
When loading descriptor caches, we would accidentally reinitialize the descriptor cache when seeing that one already exists. This should have only been initializing the cache when one does not exist. However this code itself is unnecessary as the act of looking up the cache to add to it will initialize it if it didn't already exist.
This issue could be hit by trying to load a wallet that had imported a multisig descriptor. The wallet would fail to load.
A test has been added to wallet_importdescriptors.py to catch this case. Another test case has also been added to check that loading a wallet with only single key descriptors works.

fab5586122 doc: Use precise permission flags where possible (MarcoFalke)
Pull request description:
Instead of mentioning the all-encompassing `-whitelist*` settings, change the docs to mention the exact permission flag that will influence the behaviour.
This is needed because in the future, the too-broad `-whitelist*` settings (they either include *all* permission flags or apply to *all* peers) might be deprecated to require the permission flags to be enumerated.
Alternatively, in the future there could be an RPC to set the net permission flags on an existing connection, in which case the `-whitelist*` terminology is of no help.

Mockable time is also type-safe, since it uses `std::chrono`

Pull request description:
This is another intermediate part of the Coinstats Index (tracked in #18000).
Sjors suggested [here](https://github.com/bitcoin/bitcoin/pull/18000#issuecomment-641423019) that the part of the changes in #19145 that don't rely on the new `hash_type` muhash, i.e. that are for `hash_type=none`, could be merged separately from everything involving muhash. So these changes are extracted from #19145 here and can be merged without any other requirements.
Building the index with no UTXO set hash is still valuable because `gettxoutsetinfo` can still be used to audit the `total_amount` for example. By itself this PR is not a huge improvement, `hash_type=none` is speeding up `gettxoutsetinfo` by about 10%, but it enables the implementation of an index on top of it in a follow-up and that means large parts of the index code of Coinstats Index can be merged while reviews for the hashing algorithm might take longer.

d8e9ca66d1 walletdb: Move Rewrite into BerkeleyDatabase (Andrew Chow)
91d109156d walletdb: Move PeriodicFlush into WalletDatabase (Andrew Chow)
8f1bcf8b7b walletdb: Combine VerifyDatabaseFile and VerifyEnvironment (Andrew Chow)
Pull request description:
The `BerkeleyBatch` class has 4 static functions that operate on `BerkeleyDatabase` or `BerkeleyEnvironment`. It doesn't make sense for these to be standalone nor for them to be static functions. So instead, move them from `BerkeleyBatch` into `BerkeleyDatabase` and make them member functions instead of static.
`BerkeleyBatch::VerifyEnvironment` and `BerkeleyBatch::VerifyDatabaseFile` are combined into a single `BerkeleyDatabase::Verify` function that operates on that `BerkeleyDatabase` object.
`BerkeleyBatch::Rewrite` and `BerkeleyBatch::PeriodicFlush` both took a `BerkeleyDatabase` as an argument and did stuff on it. So we just make it a member function so it doesn't need to take a database as an argument.
Part of #18971
