The legacy wallet allowed to import any raw script, without checking if
it was valid or not. Appending it to the watch-only set.
This causes a crash in the migration process because we are only
expecting to find valid scripts inside the legacy spkm.
These stored scripts internally map to `ISMINE_NO` (same as if they
weren't stored at all..).
So we need to check for these special case, and take into account that
the legacy spkm could be storing invalid not watched scripts.
Which, in code words, means IsMineInner() returning IsMineResult::INVALID
for them.
Closes #21070
v21.0 introduced a behaviour changed noted in #21070 where using a config value
`rpcallowip=::0` no longer also permitted ipv4 ip addresses.
The rpc_bind.py functional test covers this new behaviour already by checking
that the list of bind addresses exactly matches what is expected so this
commit only updates the documentation.

Pull request description:
Leveldb headers are currently included in the `dbwrapper.h` file and thus available to many of Bitcoin Core's source files. However, leveldb-specific functionality should be abstracted by the `dbwrapper` and does not need to be available to the rest of the code. Having leveldb included in a widely-used header such as `dbwrapper.h` bloats the entire project's header tree.
The `dbwrapper` is a key component of the libbitcoinkernel library. Future users of this library would not want to contend with having the leveldb headers exposed and potentially polluting their project's namespace.
For these reasons, the leveldb headers are removed from the `dbwrapper` by moving leveldb-specific code to the implementation file and creating a [pimpl](https://en.cppreference.com/w/cpp/language/pimpl) where leveldb member variables are indispensable. As a final step, the leveldb include flags are removed from the `BITCOIN_INCLUDES` and moved to places where the dbwrapper is compiled.

034f61f83b p2p: Protect extra full outbound peers by network (Martin Zumsande)
654d9bc276 p2p: Introduce data struct to track connection counts by network (Amiti Uttarwar)
Pull request description:
This is joint work with mzumsande.
This is a proposal to diversify outbound connections with respect to reachable networks. The existing logic evaluates peers for connection based purely on the frequency of available addresses in `AddrMan`. This PR adds logic to automatically connect to alternate reachable networks and adds eviction logic that protects one existing connection to each network.
For instance, if `AddrMan` is populated primarily with IPv4 and IPv6 addresses and only a handful of onion addresses, it is likely that we won't establish any automatic outbound connections to Tor, even if we're capable of doing so. For smaller networks like CJDNS, this is even more of an issue and often requires adding manual peers to ensure regularly being connected to the network.
Connecting to multiple networks improves resistance to eclipse attacks for individual nodes. It also benefits the entire p2p network by increasing partition resistance and privacy in general.
The automatic connections to alternate networks is done defensively, by first filling all outbound slots with random addresses (as in the status quo) and then adding additional peers from reachable networks the node is currently not connected to. This approach ensures that outbound slots are not left unfilled while attempting to connect to a network that may be unavailable due to a technical issue or misconfiguration that bitcoind cannot detect.
Once an additional peer is added and we have one more outbound connection than we want, outbound eviction ensures that peers are protected if they are the only ones for their network.
Manual connections are also taken into account: If a user already establishes manual connections to a trusted peer from a network, there is no longer a need to make extra efforts to ensure we also have an automatic connection to it (although this may of course happen by random selection).

Pull request description:
This simplifies the serialization code a bit and should also make it a bit faster.
* use fold expressions instead of recursive calls. This simplifies the code, makes it most likely faster because it reduces the number of function calls, and compiles faster because there are fewer template instantiations.
* use `if constexpr` instead of unnecessarily creating a temporary object only to call the right overload. This is used for `std::vector` and `prevector` serialization.

It is incorrect to assert that `cache.HaveCoin()` will always be `true`
if `backend.HaveCoin()` is. The coin could well have been marked as
spent in the cache but not yet flushed, in which case `cache.HaveCoin()`
would return `false`.
Note this was never hit because `exists_using_have_coin_in_backend` is
currently never `true` (it's the default implementation of `CCoinsView`.
However this might change if we were to add a target where the backend
is a `CCoinsViewDB`.
Diversify outbound connections with respect to
networks: Every ~5 minutes, try to add an extra connection
to a reachable network which we currently don't have a connection to.
This is done defensively - only try management with respect to networks
after all existing outbound slots are filled.
The resulting situation with an extra outbound peer will be handled
by the extra outbound eviction logic, which protects peers from
eviction if they are the only ones for their network.

025fda0a76 fuzz: addrman, avoid `ConsumeDeserializable` when possible (brunoerg)
Pull request description:
Using specific functions like `ConsumeService`, `ConsumeAddress` and `ConsumeNetAddr` may be more effective than using `ConsumeDeserializable`. They always return some value while `ConsumeDeserializable` may return `std::nullopt`.
E.g.: In this part of the code, if `op_net_addr` is `std::nullopt`, we basically generated the addresses (if so) unnecessarily, because we won't be able to use them:
```cpp
std::vector<CAddress> addresses;
LIMITED_WHILE(fuzzed_data_provider.ConsumeBool(), 10000) {
const std::optional<CAddress> opt_address = ConsumeDeserializable<CAddress>(fuzzed_data_provider);
if (!opt_address) {
break;
}
addresses.push_back(*opt_address);
}
const std::optional<CNetAddr> opt_net_addr = ConsumeDeserializable<CNetAddr>(fuzzed_data_provider);
if (opt_net_addr) {
addr_man.Add(addresses, *opt_net_addr, std::chrono::seconds{ConsumeTime(fuzzed_data_provider, 0, 100000000)});
}
```
Also, if we are not calling `Add` effectively, it would also be affect other functions that may "depend" on it.

Rather than using a bloom filter to track announced invs, simply allow
a peer to request any tx that entered the mempool prior to the last INV
message we sent them. This also obsoletes the UNCONDITIONAL_RELAY_DELAY.
