Merge bitcoin/bitcoin#22211: net: relay I2P addresses even if not reachable (by us) 
7593b06bd1 test: ensure I2P addresses are relayed (Vasil Dimov)
e7468139a1 test: make CAddress in functional tests comparable (Vasil Dimov)
33e211d2a4 test: implement ser/unser of I2P addresses in functional tests (Vasil Dimov)
86742811ce test: use NODE_* constants instead of magic numbers (Vasil Dimov)
ba45f02708 net: relay I2P addresses even if not reachable (by us) (Vasil Dimov)

Pull request description:

  Nodes that can reach the I2P network (have set `-i2psam=`) will relay
  I2P addresses even without this patch. However, nodes that can't reach
  the I2P network will not. This was done as a precaution in
  https://github.com/bitcoin/bitcoin/pull/20119 before anybody could
  connect to I2P because then, for sure, it would have been useless.

  Now, however, we have I2P support and a bunch of I2P nodes, so get all
  nodes on the network to relay I2P addresses to help with propagation,
  similarly to what we do with Tor addresses.

  laanwj:
    Code review ACK 7593b06bd1
  kristapsk:
    ACK 7593b06bd1. Code looks correct, tested that functional test suite passes and also that `test/functional/p2p_addrv2_replay.py` fails if I undo changes in `IsRelayable()`.

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

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

What is Bitcoin?

Bitcoin is an experimental digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Bitcoin Core is the name of open source software which enables the use of this currency.

For more information read the original Bitcoin whitepaper.

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.
