Sergey Biryukov 832b6c35f3 Cache API: Introduce wp_cache_supports() function.
WordPress has recently introduced a variety of caching API improvements:

* `wp_cache_add_multiple()`
* `wp_cache_set_multiple()`
* `wp_cache_get_multiple()`
* `wp_cache_delete_multiple()`
* `wp_cache_flush_runtime()`
* `wp_cache_flush_group()`

Although WordPress core provides a compatibility layer if these functions are missing from third-party object cache implementations, there should be a method of checking whether the cache backend supports a particular feature.

This commit aims to improve developer experience by allowing third-party object cache plugins to declare a `wp_cache_supports()` function and correctly list their supported features:

* `add_multiple`
* `set_multiple`
* `get_multiple`
* `delete_multiple`
* `flush_runtime`
* `flush_group`

Note: The `wp_cache_supports()` function replaces and supersedes the `wp_cache_supports_group_flush()` function added earlier.

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.
