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.

  ---

  This pull request is part of the [libbitcoinkernel project](https://github.com/bitcoin/bitcoin/issues/27587), and more specifically its stage 1 step 3 "Decouple most non-consensus headers from libbitcoinkernel".

654d9bc27647fb3797001472e2464dededb45d3f 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).

  - https://learn.microsoft.com/en-us/windows/python/faqs#what-is-py-exe-

  One of its features is the correct handling of shebang lines like the one we use: `#!/usr/bin/env python3`.

  However, Windows OS app execution aliases might [interfere](https://learn.microsoft.com/en-us/windows/python/faqs#why-does-running-python-exe-open-the-microsoft-store-) with the launcher's behaviour. Such aliases are enabled on Windows 11 by default:

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.

1b52d16d07 p2p: network-specific management of outbound connections
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.

fabaa85c017467336c7f94ddd83c44935957c919 ci: Move ASan USDT to persistent_worker (MarcoFalke)

Pull request description:

  To run the USDT functional tests, the ASan task currently requires the container host to run the Ubuntu Lunar Linux kernel (or later). Cirrus CI is the only provider that allows to spin up full VMs with Ubuntu Lunar, however they will start to charge for all tasks (See slightly related discussion in https://github.com/bitcoin/bitcoin/issues/28098).

  Since it is cheaper and recommended by Cirrus CI to just run a persistent worker, do that.

  Also, using a persistent worker allows to make use of the docker image cache.

Merge bitcoin/bitcoin#27918: fuzz: addrman, avoid ConsumeDeserializable when possible
025fda0a76893d09d19ec9a6c0ba86ad11c466f7 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.

Pull request description:

  Closes https://github.com/bitcoin/bitcoin/issues/27140

  Adds test coverage for https://github.com/bitcoin/bitcoin/pull/20516 to ensure that https://github.com/bitcoin/bitcoin/issues/20511 is completed and may be closed.

  This PR adds a test case to `feature_anchors.py` where an onion v3 address is set as a blocks-only relay peer and then shutdown, ensuring that the address is saved to anchors.dat in addrv2 format. We then ensure that bitcoin attempts to reconnect to that anchor address on restart.

  To compute the addrv2 serialization of the onion v3 address, I added logic to `CAddress` in `messages.py`. This new logic is covered by extending `p2p_addrv2_relay.py` to include an onion v3 address. Future work will be adding coverage for ipv6, torv2 and cjdns in these modules and also `feature_proxy.py`

  Also includes de/serialization unit test for `CAddress` in test framework.

2c0c6f44770403899bd8514ad7343356853bf38c test: dedup file hashing using `sha256sum_file` helper (Sebastian Falbesoner)

Pull request description:

  Rather than doing the open/read/hash-steps manually in the affected functional tests, we can just use the `sha256sum_file` helper from the utils module instead.

  Note that for the tool_wallet.py test, the used hash is changed from sha1 to sha256, but as the only purpose is to detect file content changes, this doesn't matter. Also, the optimization using `memoryview` is overkill here, as the opened file has only a size of 24KiB and determining the hash via the helper doesn't take longer than a few hundred micro-seconds on my machine.

The context of this commit is an effort to decouple the dbwrapper header
file from leveldb includes. To this end, the includes are moved to the
dbwrapper implementation file. This is done as part of the kernel
project to reduce the number of required includes for users of the
kernel.
