Subject: utest: v2, now with more isolation

* C23 required.
* Less macro voodoo magic.
* The test declaration API changed.
* Now there's a test type with the test data.
* Now it's possible to set a time out for each test.
* It's now also possible to initialize data for each test separately.
* More importantly, each test is now isolated in its own process, so
  that we beautifully report a crash and continue with the rest.
* Still less than 500loc even with all the comments!
