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.
  - Raised as topic during [bitcoin-core-dev meeting](https://www.erisian.com.au/bitcoin-core-dev/log-2021-03-25.html#l-954)

Don't schedule class PeerManagerImpl's background tasks from its
constructor, but instead do that from a separate method,
StartScheduledTasks(), that can be called later at the end of startup,
after other things, such as the active chain, are initialzed.

6f6b7df6bd [init] Disallow starting up with conflicting paramters for -dnsseed and -forcednsseed 
-dnsseed determines whether we run ThreadDNSAddressSeed and potentially query
the DNS seeds for addresses. -forcednsseed tells the node to force querying the
DNS seeds even if we have sufficient addresses or current connections.

This commit disallows starting up with explicitly conflicting parameters.

9c08719778 [test] Introduce test logic to query DNS seeds 
This commit introduces a DNS seed to the regest chain params in order to add
coverage to the DNS querying logic.

The first test checks that we do not query DNS seeds if we are able to
succesfully connect to 2 outbound connections. Since we participate in ADDR
relay with those connections, including sending a GETADDR message during the
VERSION handshake, querying the DNS seeds is unnecessary.

Fix whitespace in touched files 
Leaving the incorrect indentation would be frustrating because:
* Some editor may fix up the whitespace when editing a file, so before
  commiting the whitespace changes need to be undone.
* It makes it harder to use clang-format-diff on a change.

Can be trivially reviewed with --word-diff-regex=. --ignore-all-space

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.

Merge bitcoin/bitcoin#22528: refactor: move GetTransaction to node/transaction.cpp 
f685a13bef doc: GetTransaction()/getrawtransaction follow-ups to #22383 (John Newbery)
abc57e1f08 refactor: move `GetTransaction(...)` to node/transaction.cpp (Sebastian Falbesoner)

Pull request description:

  ~This PR is based on #22383, which should be reviewed first~ (merged by now).

  In [yesterday's PR review club session to PR 22383](https://bitcoincore.reviews/22383), the idea of moving the function `GetTransaction(...)` from src/validation.cpp to src/node/transaction.cpp came up. With this, the circular dependency "index/txindex -> validation -> index/txindex" is removed (see change in `lint-circular-dependencies.sh`). Thanks to jnewbery for suggesting and to sipa for providing historical background.

  Relevant IRC log:
  ```
  17:52 <jnewbery> Was anyone surprised that GetTransaction() is in validation.cpp? It seems to me that node/transaction.cpp would be a more appropriate place for it.
  17:53 <raj_> jnewbery, +1
  17:53 <stickies-v> agreed!
  17:54 <glozow> jnewbery ya
  17:54 <jnewbery> seems weird that validation would call into txindex. I wonder if we remove this function, then validation would no longer need to #include txindex
  17:54 <sipa> GetTransaction predates node/transaction.cpp, and even the generic index framework itself :)
  17:55 <sipa> (before 0.8, validation itself used the txindex)
  17:55 <jnewbery> (and GetTransaction() seems like a natural sibling to BroadcastTransaction(), which is already in node/transaction.cpp)
  17:55 <jnewbery> sipa: right, this is not meant as a criticism of course. Just wondering if we can organize things a bit more rationally now that we have better separation between things.
  17:55 <sipa> jnewbery: sure, just providing background
  17:56 <sipa> seems very reasonable to move it elsewhere now
  ```

  The commit should be trivial to review with `--color-moved`.

8858e88c84 p2p: refactor: tidy up `PeerManagerImpl::Misbehaving(...)` (Sebastian Falbesoner)

Pull request description:

  This simple refactoring PR has the goal to improve the readability of the `Misbehaving` method by

  - introducing constant variables `score_before` and  `score_now` (to avoid repeatedly calculating the former)
  - deduplicating calls to LogPrint(), eliminates else-branch

rpc: Block until synced if coinstatsindex is used in gettxoutsetinfo 
During initial sync after startup the gettxoutsetinfo RPC will still return an error while catching up. However, after the initial sync the index will not error immediately anymore when it's in the process of syncing to the tip while being called. Instead it will block until synced and then return the response.

Merge bitcoin/bitcoin#13533: [tests] Reduced number of validations in tx_validationcache_tests 
c3e111a7da Reduced number of validations in `tx_validationcache_tests` to keep the run time reasonable. (lucash-dev)

Pull request description:

  Following a suggestion in the comments, changed `ValidateCheckInputsForAllFlags` from testing all possible flag combinations to testing a random subset. Also created a new enum constant for the highest flag, so that this test doesn’t keep testing an incomplete subset in case a new flag is added.

  Timing for `checkinputs_test`:
  ```
  Before:   6.8s
  After:    3.7s
  ----------------
  Saved:    3.1s (45%)
  ```

  This PR was split from #13050. Also see #10026.

Merge bitcoin/bitcoin#22383: rpc: Prefer to use txindex if available for GetTransaction 
78f4c8b98e prefer to use txindex if available for GetTransaction (Jameson Lopp)

Pull request description:

  Fixes #22382

  Motivation: prevent excessive disk reads if txindex is enabled.

  Worth noting that this could be argued to be less of a bug and more of an issue of undefined behavior. If a user calls GetTransaction with the wrong block hash, what should happen?
