Felix Arntz e6fda09261 Multisite: Handle sites cache invalidation more granularly for option updates.
Previously `update_blog_option()` would trigger an invalidation of that site's entire cache although these changes did not affect the content of these caches. Furthermore changes to the special options `blogname`, `siteurl` and `post_count` should not invalidate the entire cache of that site, but only their respective site details cache. The option `home` now has the same behavior as it also belongs to the site details, but did not invalidate the cache at all previously.

Several new unit tests confirm these changes work as expected.

Fixes #40063.

The short version:

1. Create a clean MySQL database and user.  DO NOT USE AN EXISTING DATABASE or you will lose data, guaranteed.

2. Copy wp-tests-config-sample.php to wp-tests-config.php, edit it and include your database name/user/password.

3. $ svn up

4. Run the tests from the "trunk" directory:
   To execute a particular test:
      $ phpunit tests/phpunit/tests/test_case.php
   To execute all tests:
      $ phpunit

Notes:

Test cases live in the 'tests' subdirectory.  All files in that directory will be included by default.  Extend the WP_UnitTestCase class to ensure your test is run.

phpunit will initialize and install a (more or less) complete running copy of WordPress each time it is run.  This makes it possible to run functional interface and module tests against a fully working database and codebase, as opposed to pure unit tests with mock objects and stubs.  Pure unit tests may be used also, of course.

Changes to the test database will be rolled back as tests are finished, to ensure a clean start next time the tests are run.

phpunit is intended to run at the command line, not via a web server.
