Pull request description:

  Log messages from leveldb and libevent libraries in the severity+level based log format introduced in bitcoin/bitcoin#24464.

  Example of messages before:
  ```
  2022-05-24T18:11:57Z [libevent] libevent: event_add: event: 0x55da963fcc10 (fd 10), EV_READ    call 0x7f1c7a254620
  2022-05-24T18:11:57Z [libevent] libevent: Epoll ADD(1) on fd 10 okay. Old events were 0; read change was 1 (add); write change was 0 (none); close change was 0 (none)
  2022-05-24T18:12:08Z leveldb: Generated table #609127@1: 6445 keys, 312916 bytes
  2022-05-24T18:12:08Z leveldb: Generated table #609128@1: 5607 keys, 268548 bytes
  2022-05-24T18:12:08Z leveldb: Generated table #609129@1: 189 keys, 9384 bytes
  2022-05-24T18:12:08Z leveldb: Generated table #609130@1: 293 keys, 13818 bytes
  ```

  Example of messages after:
  ```
  2022-05-24T17:59:52Z [libevent:debug] event_add: event: 0x5652f44dac10 (fd 10), EV_READ    call 0x7f210f2e6620
  2022-05-24T17:59:52Z [libevent:debug] Epoll ADD(1) on fd 10 okay. Old events were 0; read change was 1 (add); write change was 0 (none); close change was 0 (none)
  2022-05-24T17:59:53Z [leveldb:debug] Recovering log #1072
  2022-05-24T17:59:53Z [leveldb:debug] Level-0 table #1082: started
  2022-05-24T17:59:53Z [leveldb:debug] Level-0 table #1082: 193 bytes OK
  2022-05-24T17:59:53Z [leveldb:debug] Delete type=3 #1070
  2022-05-24T17:59:53Z [leveldb:debug] Delete type=0 #1072
  ```

  The first commit changes it so that messages with level Warning and Error are always logged independent of the `-debug` setting. I think this is useful to make sure warnings and errors, which tend to be important, are not lost. In the future this should be made more configurable.

  Last commit changes LogPrintLevel argument order to category, severity: This is more consistent with the other functions, as well as with the logging output itself. If we want to make this change, we should do it before it's all over the place.

README.md

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.
