Jonny Harris 94d2f4e68b Options, Meta APIs: Prevent unnecessary database updates caused by strict comparisons in update_network_option.
Previously, in the update_network_option function, strict comparisons between old and new values could erroneously trigger updates in cases where there was no actual change in values. Building upon the groundwork laid in #22192, this commit introduces the use of the _is_equal_database_value function to accurately compare values before initiating any database updates. This change ensures consistency between the behaviors of `update_option` and `update_network_option`.

Furthermore, we have incorporated similar workarounds that were previously implemented in [56717]. These changes ensure that the raw version of network option values is considered in the comparisons, enhancing the overall reliability of the update process.

Fixes #59360.

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.
