Pull request description:
This fixes three issues in addrman unserialization.
1. An addrman entry can appear in up to 8 new table buckets. We store this entry->bucket indexing during shutdown so that on restart we can restore the entries to their correct buckets. Commit ec45646de9 broke the deserialization code so that each entry could only be put in up to one new bucket.
2. Unserialization may result in an entry appearing in a 9th bucket. If the entry already appears in 8 buckets don't try to place it in another bucket.
3. We unnecessarily rebucket when reading a peers.dat with file version 1. Don't do that.

This fixes issue #19388. The changes are as follows:
- Add a new flag to configure, --enable-fuzz-binary, which allows building test/fuzz/fuzz regardless of whether we are building to do actual fuzzing
- Set -DPROVIDE_MAIN_FUNCTION whenever --enable-fuzz is no
- Add the following libraries to FUZZ_SUITE_LD_COMMON:
- LIBBITCOIN_WALLET
- SQLLITE_LIBS
- BDB_LIBS
- if necessary, some or all of:
- NATPMP_LIBS
- MINIUPNPC_LIBS
- LIBBITCOIN_ZMQ / ZMQ_LIBS

Merry Bitcoin Christmas! Ho ho ho 🎄✨
This PR updates `-netinfo` to:
- use the getpeerinfo `connection_type` field (and no longer use getpeerinfo `relaytxes` for block-relay detection)
- display manual peers count, if any, in the outbound row
- display the block relay counts in the outbound row only
- display high-bandwidth BIP152 compact block relay peers (`hb` column, to `.` and from `*`)
- add support for displaying I2P network peers, if any are present
Testing and review welcome! How to test:
- to run the full live dashboard (on Linux): `$ watch --interval 1 --no-title ./src/bitcoin-cli -netinfo 4`

20677ffa22 validation: Guard all chainstates with cs_main (Carl Dong)
Pull request description:
```
This avoids a potential race-condition where a thread is reading the
ChainstateManager::m_active_chainstate pointer while another one is
writing to it. There is no portable guarantee that reading/writing the
pointer is thread-safe.
This is also done in way that mimics ::ChainstateActive(), so the
transition from that function to this method is easy.

Code review ACK 20677ffa22. It is safer to have these new `GUARDED_BY` annotations and locks than not to have them, but in the longer run I think every `LOCK(cs_main)` added here and added earlier in f92dc6557a from #20749 should be removed and replaced with `EXCLUSIVE_LOCKS_REQUIRED(cs_main)` on the accessor methods instead. `cs_main` is a high level lock that should be explicitly acquired at a high level to prevent the chain state from changing. It shouldn't be acquired recursively in low-level methods just to read pointer values atomically.

Pull request description:
This PR introduces per-peer message capture into Bitcoin Core. 📓
## Purpose
The purpose and scope of this feature is intentionally limited. It answers a question anyone new to Bitcoin's P2P protocol has had: "Can I see what messages my node is sending and receiving?".
## Functionality
When a new debug-only command line argument `capturemessages` is set, any message that the node receives or sends is captured. The capture occurs in the MessageHandler thread. When receiving a message, it is captured as soon as the MessageHandler thread takes the message off of the vProcessMsg queue. When sending, the message is captured just before the message is pushed onto the vSendMsg queue.
The message capture is as minimal as possible to reduce the performance impact on the node. Messages are captured to a new `message_capture` folder in the datadir. Each node has their own subfolder named with their IP address and port. Inside, received and sent messages are captured into two binary files, msgs_recv.dat and msgs_sent.dat, like so:
```
message_capture/203.0.113.7:56072/msgs_recv.dat
message_capture/203.0.113.7:56072/msgs_sent.dat
```
Because the messages are raw binary dumps, included in this PR is a Python parsing tool to convert the binary files into human-readable JSON. This script has been placed on its own and out of the way in the new `contrib/message-capture` folder. Its usage is simple and easily discovered by the autogenerated `-h` option.
## Future Maintenance
I sympathize greatly with anyone who says "the best code is no code".
The future maintenance of this feature will be minimal. The logic to deserialize the payload of the p2p messages exists in our testing framework. As long as our testing framework works, so will this tool.
Additionally, I hope that the simplicity of this tool will mean that it gets used frequently, so that problems will be discovered and solved when they are small.
## FAQ
"Why not just use Wireshark"
Yes, Wireshark has the ability to filter and decode Bitcoin messages. However, the purpose of the message capture added in this PR is to assist with debugging, primarily for new developers looking to improve their knowledge of the Bitcoin Protocol. This drives the design in a different direction than Wireshark, in two different ways. First, this tool must be convenient and simple to use. Using an external tool, like Wireshark, requires setup and interpretation of the results. To a new user who doesn't necessarily know what to expect, this is unnecessary difficulty. This tool, on the other hand, "just works". Turn on the command line flag, run your node, run the script, read the JSON. Second, because this tool is being used for debugging, we want it to be as close to the true behavior of the node as possible. A lot can happen in the SocketHandler thread that would be missed by Wireshark.
Additionally, if we are to use Wireshark, we are at the mercy of whoever it maintaining the protocol in Wireshark, both as to it being accurate and recent. As can be seen by the **many** previous attempts to include Bitcoin in Wireshark (google "bitcoin dissector") this is easier said than done.
Lastly, I truly believe that this tool will be used significantly more by being included in the codebase. It's just that much more discoverable.

Since these chainstates are:
1. Also vulnerable to the race condition described in the previous
commit
2. Documented as having similar semantics as m_active_chainstate
we should also protect them with ::cs_main.

Post #18710, there isn't much left using `boost::thread_group`, so should just be able to replace it with the standard library. This also removes the last use of `boost::thread_interrupted`.
After this change, last piece of Boost Thread we'd be using is `boost::shared_mutex`. See the commentary [here](https://github.com/bitcoin/bitcoin/issues/16684#issuecomment-726214696) as to why it may be non-trivial to swap that for `std::shared_mutex` in the near future.

Overall PR: #20158 (tree-wide: De-globalize ChainstateManager)
Note to reviewers:
1. This bundle may _apparently_ introduce usage of `g_chainman` or `::Chain(state|)Active()` globals, but these are resolved later on in the overall PR. [Commits of overall PR](https://github.com/bitcoin/bitcoin/pull/20158/commits)
2. There may be seemingly obvious local references to `ChainstateManager` or other validation objects which are not being used in callers of the current function in question, this is done intentionally to **_keep each commit centered around one function/method_** to ease review and to make the overall change systematic. We don't assume anything about our callers. Rest assured that once we are considering that particular caller in later commits, we will use the obvious local references. [Commits of overall PR](https://github.com/bitcoin/bitcoin/pull/20158/commits)
3. When changing a function/method that has many callers (e.g. `LookupBlockIndex` with 55 callers), it is sometimes easier (and less error-prone) to use a scripted-diff. When doing so, there will be 3 commits in sequence so that every commit compiles like so:
1. Add `new_function`, make `old_function` a wrapper of `new_function`, divert all calls to `old_function` to `new_function` **in the local module only**
2. Scripted-diff to divert all calls to `old_function` to `new_function` **in the rest of the codebase**
3. Remove `old_function`

74d23bf7fb rpc: document RPC_TRANSACTION_ALREADY_IN_CHAIN exception (Jarol Rodriguez)
Pull request description:
It is not documented in the `RPCHelpMan` of `sendrawtransaction` that if you attempt to send a transaction which already exists in a block, an `RPC_TRANSACTION_ALREADY_IN_CHAIN` exception will be raised. It is best to make developers aware of this so that it can be properly caught and avoid any headaches.
Closes#5638
