7ff05358a9 [mempool] Remove error suppression on upgrade
In 0.21, we added unbroadcast txids to mempool.dat. Commit 9c8a55d
added a try-block to prevent throwing a "failed to deserialize mempool data"
error when a user upgrades from 0.21 to 0.22. This exception handling is no
longer useful, so now we can remove it.

Merge #20736: rpc: Replace boost::variant with std::variant for RPCArg.m_fallback
fa749fbea3 rpc: Replace boost::variant with std::variant for RPCArg.m_fallback (MarcoFalke)

Pull request description:

  Now that we can use std::variant from the vanilla standard library, drop the third-party boost variant dependency.

  Patch is split out from #20480. A step-by-step replacement is possible because we don't have our own `Variant` wrapper and the source code specifies `boost::variant` explicitly.
  I think a step-by-step replacement should be preferred, because it simplifies review.

Merge #20817: lint: update list of spelling linter false positives, bump to codespell 2.0.0
f3ba916e8b lint: ignore gitian keys file for spelling linter (Sebastian Falbesoner)
da289a6c4a lint: update list of spelling linter false positives (Sebastian Falbesoner)
a0022f1cfb test: bump codespell linter version to 2.0.0 (Sebastian Falbesoner)

Pull request description:

  This small patch updates the ignore list for the spelling linter script (which uses `codespell`), both removing false-positives that are not relevant anymore and adding new ones. As [suggested by jonatack](https://github.com/bitcoin/bitcoin/pull/20762#issuecomment-750889701)~~, whose last name is now also part of the list :)~~. Also changed the linter script to not check the gitian keys file, as [suggested by hebasto](https://github.com/bitcoin/bitcoin/pull/20817#discussion_r550763409). The codespell version used is bumped to most recent version 2.0.0, which is more aware of some terms that were previously needed in the ignorelist for v1.17.1, see https://github.com/bitcoin/bitcoin/pull/20817#issuecomment-753428669.

    ACK f3ba916e8b I don't know if there are any particular issues with bumping codespell to v2.0.0, but locally running the spelling linter and the cirrus job at https://cirrus-ci.com/task/5004066998714368 both LGTM. Thanks for also verifying and removing the unused words from the ignore list.

Merge #20760: test: Set correct nValue for multi-op-return policy check
fad140e311 test: Set correct nValue for multi-op-return policy check (MarcoFalke)

Pull request description:

  `CTxOut::nValue` is default-initialized to `-1`. The dust-threshold for `OP_RETURN` outputs is `0`. Thus, the policy failure would be `dust` instead of `multi-op-return`. The test only passes because the dust check is currently not run.

  Avoid that confusion by setting the value to `0`, to ensure the dust check passes.

Merge #20649: refactor: Remove nMyStartingHeight from CNode/Connman
faaa4f2b6a refactor: Remove nMyStartingHeight from CNode/Connman (MarcoFalke)

Pull request description:

  CNode and CConnman keep track of the active chain height when CNodes have been created, but apart from serializing the int once (when sending a version message), it is unused. So it can simply be removed in favor of a single int in PeerMan that can do the same.

Pull request description:

  The goal of this PR is to be able to depend on `m_inbound_onion` in AttemptToEvictConnection in #20197:

  - asserts `CNode::m_inbound_onion` is inbound in the CNode ctor to have a validity check at the class boundary
  - fixes a unit test and a fuzz utility that were passing invalid inbound onion values to the CNode ctor
  - drops an unneeded check in `CNode::ConnectedThroughNetwork()` for its inbound status
  - adds a public getter `IsInboundOnion()` that also allows unit testing it
  - adds unit test coverage

Merge #20451: lint: run mypy over contrib/devtools
1ef2138c0d lint: run mypy over contrib/devtools (fanquake)

Pull request description:

  wumpus mentioned on IRC that we don't currently run `mypy` over the `contrib/devtools` directory, and that it would likely be worthwhile given #20434. This just adds that dir to the linter, as well as some missing annotations to fix existing errors. Note that now we require Python 3.6 we can make use of variable annotations.

  master (patched to check contrib devtools):
  ```bash
  test/lint/lint-python.sh
  contrib/devtools/symbol-check.py:154: error: Incompatible types in assignment (expression has type "List[str]", variable has type "str")
  contrib/devtools/circular-dependencies.py:35: error: Need type annotation for 'deps' (hint: "deps: Dict[<type>, <type>] = ...")
  contrib/devtools/circular-dependencies.py:67: error: Need type annotation for 'closure' (hint: "closure: Dict[<type>, <type>] = ...")
  Found 4 errors in 3 files (checked 187 source files)
  ```

  I haven't quite gone as far as to add annotations like
  ```python
  CHECKS: Dict[str, List[Tuple[str, Callable[[Any], bool]]]] = {...
  ```
  to `symbol-check.py`.
