Merge bitcoin/bitcoin#28218: refactor: Make IsInitialBlockDownload & NotifyHeaderTip not require a Chainstate 
94a98fbd1d assumeutxo cleanup: Move IsInitialBlockDownload & NotifyHeaderTip to ChainstateManager (Ryan Ofsky)

Pull request description:

  This change makes `IsInitialBlockDownload` and `NotifyHeaderTip` functions no longer tied to individual `Chainstate` objects. It makes them work with the `ChainstateManager` object instead so code is simpler and it is no longer possible to call them incorrectly with an inactive `Chainstate`.

  This change also makes `m_cached_finished_ibd` caching easier to reason about, because now there is only one cached value instead of two (for background and snapshot chainstates) so the cached IBD state now no longer gets reset when a snapshot is loaded.

  There should be no change in behavior because these functions were always called on the active `ChainState` objects.

  These changes were discussed previously https://github.com/bitcoin/bitcoin/pull/27746#discussion_r1246868905 and https://github.com/bitcoin/bitcoin/pull/27746#discussion_r1237552792 as possible followups for that PR.

Bitcoin Core integration/staging tree

https://bitcoincore.org

For an immediately usable, binary version of the Bitcoin Core software, see https://bitcoincore.org/en/download/.

What is Bitcoin Core?

Bitcoin Core connects to the Bitcoin peer-to-peer network to download and fully validate blocks and transactions. It also includes a wallet and graphical user interface, which can be optionally built.

Further information about Bitcoin Core is available in the doc folder.

License

Bitcoin Core is released under the terms of the MIT license. See COPYING for more information or see https://opensource.org/licenses/MIT.

Development Process

The master branch is regularly built (see doc/build-*.md for instructions) and tested, but it is not guaranteed to be completely stable. Tags are created regularly from release branches to indicate new official, stable release versions of Bitcoin Core.

The https://github.com/bitcoin-core/gui repository is used exclusively for the development of the GUI. Its master branch is identical in all monotree repositories. Release branches and tags do not exist, so please do not fork that repository unless it is for development reasons.

The contribution workflow is described in CONTRIBUTING.md and useful hints for developers can be found in doc/developer-notes.md.

Testing

Testing and code review is the bottleneck for development; we get more pull requests than we can review and test on short notice. Please be patient and help out by testing other people's pull requests, and remember this is a security-critical project where any mistake might cost people lots of money.

Automated Testing

Developers are strongly encouraged to write unit tests for new code, and to submit new unit tests for old code. Unit tests can be compiled and run (assuming they weren't disabled in configure) with: make check. Further details on running and extending unit tests can be found in /src/test/README.md.

There are also regression and integration tests, written in Python. These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py

The CI (Continuous Integration) systems make sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically.

Manual Quality Assurance (QA) Testing

Changes should be tested by somebody other than the developer who wrote the code. This is especially important for large or high-risk changes. It is useful to add a test plan to the pull request description if testing the changes is not straightforward.

Translations

Changes to translations as well as new translations can be submitted to Bitcoin Core's Transifex page.

Translations are periodically pulled from Transifex and merged into the git repository. See the translation process for details on how this works.

Important: We do not accept translation changes as GitHub pull requests because the next pull from Transifex would automatically overwrite them again.
