Pull request description:

  Introduce the pimpl pattern for AddrMan to separate the implementation details from the externally used object representation. This reduces compile-time dependencies and conceptually clarifies AddrMan's interface from the implementation specifics.

  Since the unit & fuzz tests currently rely on accessing AddrMan internals, this PR introduces addrman_impl.h, which is exclusively imported by addrman.cpp and test files.

75290ae61e Drop us=... message in net debug for sending version message
The us=... message in the debug log when sending a version message is
always [::]:0, because we no longer send our own address there.
Therefore, this information is entirely redundant. Remove it.

5d47860334 refactor: move CAddress-without-nTime logic to net_processing
Historically, the VERSION message contains an "addrMe" and an "addrYou". As
these are sent before version negotiation is complete, the protocol version is
INIT_PROTO_VERSION (209), and in that protocol, CAddress is serialized without
nTime.

This is in fact the only situation left where a CAddress is (de)serialized
without nTime. As it's such a simple structure (CService for ip/port + uint64_t
for nServices), just inline that structure in the few places where it occurs,
and remove the logic for dealing with missing nTime from CAddress.

9778b0fec1 [net_processing] Provide debug error if code assumptions change.
Currently, this call to SetupAddressRelay will never return false because of
the previous guard that returns early if the peer is not an inbound connection.
Rather than implicitly relying on this guarantee, throw an error in the debug
build if it ever changes.

Merge bitcoin/bitcoin#22577: Close minor startup race between main and scheduler threads
703b1e612a Close minor startup race between main and scheduler threads (Larry Ruane)

Pull request description:

  This is a low-priority bug fix. The scheduler thread runs `CheckForStaleTipAndEvictPeers()` every 45 seconds (EXTRA_PEER_CHECK_INTERVAL). If its first run happens before the active chain is set up (`CChain::SetTip()`), `bitcoind` will assert:
  ```
  (...)
  2021-07-28T22:16:49Z init message: Loading block index…
  bitcoind: validation.cpp:4968: CChainState& ChainstateManager::ActiveChainstate() const: Assertion `m_active_chainstate' failed.
  Aborted (core dumped)
  ```
  I ran into this while using the debugger to investigate an unrelated problem. Single-stepping through threads with a debugger can cause the relative thread execution timing to be very different than usual. I don't think any automated tests are needed for this PR. I'll give reproduction steps in the next PR comment.

Pull request description:

  This PR builds on the test refactors extracted into #22306 (first 5 commits).

  This PR aims to reduce addr blackholes. When we receive an `addr` message that contains 10 or less addresses, we forward them to 1-2 peers. This is the main technique we use for self advertisements, so sending to peers that wouldn't relay would effectively "blackhole" the trickle. Although we cannot prevent this in a malicious case, we can improve it for the normal, honest cases, and reduce the overall likelihood of occurrence. Two known cases where peers would not participate in addr relay are if they have connected to you as a block-relay-only connection, or if they are a light client.

  This implementation defers initialization of `m_addr_known` until it is needed, then uses its presence to decide if the peer is participating in addr relay. For outbound (not block-relay-only) peers, we initialize the filter before sending the initial self announcement when processing their `version` message. For inbound peers, we initialize the filter if/when we get an addr related message (`ADDR`, `ADDRV2`, `GETADDR`). We do NOT initialize the filter based on a `SENDADDRV2` message.

  To communicate about these changes beyond bitcoin core & to (try to) ensure that no other software would be disrupted, I have:
  - Posted to the [mailing list](https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2021-April/018784.html)
  - Researched other open source clients to confirm compatibility, opened issues in all the projects & documented in https://github.com/bitcoin/bitcoin/pull/21528#issuecomment-809906430. Many have confirmed that this change would not be problematic.

1d1ef2db7e [net_processing] Defer initializing m_addr_known
Use SetupAddressRelay to only initialize `m_addr_known` as needed. For outbound
peers, we initialize the filter before sending our self announcement (not
applicable for block-relay-only connections). For inbound peers, we initialize
the filter when we get an addr related message (ADDR, ADDRV2, GETADDR).

These changes intend to mitigate address blackholes. Since an inbound peer has
to send us an addr related message to become eligible as a candidate for addr
relay, this should reduce our likelihood of sending them self-announcements.

Pull request description:

  Builds on #21009 and makes progress on remaining items in #17862

  Removing `RewindBlockIndex()` in #21009 allows the following:

  - removal of tests using `segwitheight=-1` in `p2p_segwit.py`.
  - move `test_upgrade_after_activation()` out of `p2p_segwit.py` reducing runtime
  - in turn, that allows us to drop support for `-segwitheight=-1`, which is only supported for that test.
  - that allows us to always set `NODE_WITNESS` in our local services. The only reason we don't do that is to support `-segwitheight=-1`.
  - that in turn allows us to drop all of the `GetLocalServices() & NODE_WITNESS` checks inside `net_processing.cpp`, since our local services would always include `NODE_WITNESS`

b6c5d1e450 p2p: AddrFetch - don't disconnect on self-announcements (Martin Zumsande)

Pull request description:

  AddrFetch connections (old name: oneshots) are intended to be short-lived connections on which we ask a peer for addresses via `getaddr` and disconnect after receiving them.

  This is done by disconnecting after receiving the first `addr`. However, it is no longer working as intended, because nowadays, the first `addr` a typical bitcoin core node sends is its self-announcement.
  So we'll disconnect before the peer gets a chance to answer our `getaddr`.

  I checked that this affects both `-seednode` peers specified manually, and DNS seeds when AddrFetch is used as a fallback if DNS doesn't work for us.

  The current behavior of getting peers via AddrFetch when starting with an empty addrman would be to connect to the peer, receive its self-announcement and add it to addrman, disconnect, reconnect to the same peer again as a full outbound (no other addresses in addrman) and then receive more `addr`. This is silly and not in line with AddrFetch peer being intended to be short-lived peers. 

  Fix this by only disconnecting after receiving an `addr` message of size > 1.

  [Edit] As per review discussion, this PR now also adds a timeout after which we disconnect if we haven't received any suitable `addr`, and a functional test.

just default initialize m_recent_confirmed_transactions during object

0d64b8f709 Rate limit the processing of incoming addr messages
While limitations on the influence of attackers on addrman already
exist (affected buckets are restricted to a subset based on incoming
IP / network group), there is no reason to permit them to let them
feed us addresses at more than a multiple of the normal network
rate.

This commit introduces a "token bucket" rate limiter for the
processing of addresses in incoming ADDR and ADDRV2 messages.
Every connection gets an associated token bucket. Processing an
address in an ADDR or ADDRV2 message from non-whitelisted peers
consumes a token from the bucket. If the bucket is empty, the
address is ignored (it is not forwarded or processed). The token
counter increases at a rate of 0.1 tokens per second, and will
accrue up to a maximum of 1000 tokens (the maximum we accept in a
single ADDR or ADDRV2). When a GETADDR is sent to a peer, it
immediately gets 1000 additional tokens, as we actively desire many
addresses from such peers (this may temporarily cause the token
count to exceed 1000).

The rate limit of 0.1 addr/s was chosen based on observation of
honest nodes on the network. Activity in general from most nodes
is either 0, or up to a maximum around 0.025 addr/s for recent
Bitcoin Core nodes. A few (self-identified, through subver) crawler
nodes occasionally exceed 0.1 addr/s.

  The `::Params()` global is verbose and confusing. Also it makes tests a bit harder to write because they'd have to mock a global.

  Fix all issues by simply using a member variable that points to the right params.

c0385f10a1 Remove -feefilter option (amadeuszpawlik)

Pull request description:

  net: Remove -feefilter option, as it is debug only and isn't used in any tests. Checking this option for every peer on every iteration of the message handler is unnecessary, as described in #21545.
  refactor: Move feefilter logic out into a separate `MaybeSendFeefilter(...)` function to improve readability of the already long `SendMessages(...)`. fixes  #21545

  The configuration option `-feefilter` has been added in 9e072a6e66: _"Implement "feefilter" P2P message"_
  According to the [BIP133](https://github.com/bitcoin/bips/blob/master/bip-0133.mediawiki), turning the fee filter off was ment for:
  > [...] a node [...] using prioritisetransaction to accept transactions whose actual fee rates might fall below the node's mempool min fee [in order to] disable the fee filter to make sure it is exposed to all possible txid's

  `-feefilter` was subsequently set as debug only in #8150, with the motivation that the help message was too difficult to translate.

  This picks up the closed pull request #21030 and is the first step toward fixing #21220.

  The basic idea is to move all disk access into a separate module with benefits:
  * Breaking down the massive files init.cpp and validation.cpp into logical units
  * Creating a standalone-module to reduce the mental complexity
  * Pave the way to fix validation related circular dependencies
  * Pave the way to mock disk access for testing, especially where it is performance critical (like fuzzing)

  Chronological history of this changeset:
  1. Bundle 4 (#21270) got merged
  2. Posthumous reviews were posted
  3. These changes were prepended in bundle 5
  4. More reviews were added in bundle 5
  5. Someone suggested that we split the prepended changes up to another PR
  6. This is that PR

  In the future, I will just do posthumous review changes in another PR instead. I apologize for the confusion.

Pull request description:

  This continues the work of moving application layer data into net_processing. It refactors `addr` send functionality into its own function `MaybeSendAddr()` and flattens/simplifies the code. Isolating and simplifying the addr handling code makes subsequent changes (which will move addr data and logic into net processing) easier to review.

  This is a pure refactor. There are no functional changes.

  For motivation of the project, see #19398.

935d488922 [net processing] Refactor MaybeSendAddr()
Changes to make MaybeSendAddr simpler and easier to maintain/update:

- assert invariant that node.vAddrToSend.size() can never exceed
  MAX_ADDR_TO_SEND
- erase known addresses from vAddrToSend in one pass
- no check for (vAddr.size() >= MAX_ADDR_TO_SEND) during iteration,
  since vAddr can never exceed MAX_ADDR_TO_SEND.

392a95d393 [net_processing] Keep addrman reference in PeerManager (John Newbery)
1c25adf6d2 [net] Construct addrman outside connman (John Newbery)

Pull request description:

  Addrman is currently a member variable of connman. Make it a top-level component with lifetime owned by node.context, and add a reference to addrman in peerman. This allows us to eliminate some functions in connman that are simply forwarding requests to addrman, and simplifies the connman-peerman interface.

  By constructing the addrman in init, we can also add parameters to the ctor, which allows us to test it better. See #20233, where we enable consistency checking for addrman in our functional tests.
