Sergey Biryukov fed98bd9ef Database: Correct MariaDB version check in wpdb::has_cap().
MariaDB version is reported differently between PHP versions:
* PHP 8.0.16 or later: `10.6.8-MariaDB`
* PHP 8.0.15 or earlier: `5.5.5-10.6.8-MariaDB`

The latter includes PHP 7.4.x and PHP 5.6.x as well, where the version is also reported with the `5.5.5-` prefix.

This commit makes an adjustment to `wpdb::has_cap()` to check for the correct MariaDB version.

This resolves an issue where the `utf8mb4_unicode_520_ci` collation, which is available in MariaDB since version 10.2, was previously not detected correctly.

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.
