James Nylen ce38b9c90a REST API: Avoid sending blank `Last-Modified` headers with authenticated requests.
This commit adds a new `WP_REST_Server#remove_header` method and uses it to clear the `Last-Modified` header when the "no caching" headers are sent (by default for all authenticated REST API requests).  This matches the behavior of the `nocache_headers` function used in other parts of WordPress.

Previously, the REST API would send an empty `Last-Modified` header in this situation.  Under some server and browser configurations, this causes browsers to cache authenticated REST API requests, which is undesirable.

John Blackbourn 64f8351da1 Build/Test Tools: Introduce `skipWithoutMultisite()` and `skipWithMultisite`() methods into the test suite.
This brings much needed uniformity to test skipping when a test requires Multisite or when a test should be excluded from running when Multisite is enabled.

Used in conjunction with the `@group ms-required` and `@group ms-excluded` notation, this removes a significant number of skipped tests from the default test suite run.

John Blackbourn f5f7736177 Build/Test tools: Don't override the `wp_set_auth_cookie()` and `wp_clear_auth_cookie()` functions.
Overriding pluggable functions in the test suite is asking for trouble in the future. In addition, it means the test suite can't be guaranteed to behave the same as core.

This instead introduces a `send_auth_cookies` filter which can be hooked in during the test suite to prevent these functions from attempting to send cookie headers to the client.

James Nylen 4414e3c20a REST API: Shim `post_date_gmt` for drafts / empty dates in the REST API.
Internally, WordPress uses a special `post_date_gmt` value of `0000-00-00 00:00:00` to indicate that a draft's date is "floating" and should be updated whenever the post is saved.  This makes it much more difficult for API clients to know the correct date of a draft post.

This commit provides a best guess at a `date_gmt` value for draft posts in this situation using the `date` field and the site's current timezone offset.

Also make the PHPUnit test suite correctly exit with a non-zero exit code when `wp-tests-config.php` is not present.  This was causing `grunt restapi-jsclient` to incorrectly proceed to its second step even when the first step failed with this error.

Gary Pendergast f593d8532a Tests: Restore the database connection earlier when switching test groups.
When plugins don't disable the `backupGlobals` PHPUnit option in their own tests, `$wpdb` is backed up and restored between classes of tests. The serialisation process used for this broke the database connection. This previously wasn't a problem, as it was reconnecting before each test.

[38398] introduced some changes that required the connection to be available in `setUpBeforeClass()`, earlier than in was previously reconnecting. This didn't cause warnings in Core, but it did cause warnings for plugins that don't disable the `backupGlobals` option.

The database connection now reconnects in `setUpBeforeClass()`. This change also fixes a few Core tests that weren't calling `parent::setUpBeforeClass()` or `parent::tearDown()` correctly.

Fixes #39327.

Gary Pendergast ee65fc1f80 Tests: Use a minimal theme for tests.
This functionality was originally added in [38858], using `symlink()` to put a link to the theme in WordPress' `themes` directory. Unfortunately, not all installs have write access to the `themes` directory, causing unit tests to fail.

The new method is to add the test theme directory to `$wp_theme_directories`, and fix the handful of tests that don't expect `$wp_theme_directories` to have multiple entries.

The test install/bootstrap routines now also check that `WP_DEFAULT_THEME` is defined, in case the tests are being run on a system that hasn't upgraded its' `wp-tests-config.php`.

- Comments: Read and write access to all comment data. This includes pingbacks and trackbacks.
- Terms: Read and write access to all term data.

Love your REST API, WordPress!  The infrastructure says, "Let's do lunch!" but the content API endpoints say, "You're paying!"

Boone Gorges c4c80d3dd4 Tests: Reset post-related globals after each test.
Globals like `$pages` were leaking between tests, resulting in various
bits of weirdness.

Globals will kill WordPress. Globals are killing WordPress.

See #38196.

John Blackbourn fa48bfa1d2 Built/Test Tools: Unify the way the permastructure is set when used in conjunction with re-registering the initial taxonomies. This ensure that rewrite rules for taxonomies are consistently available.

Gary Pendergast 40ebbc7713 Tests: Use `add_filter()` when it's available.
The `tests_add_filter()` helper function directly manipulates the `$wp_filter` global, instead of using `add_filter()`. We can use `add_filter()` when it's available, and fall back to manipulating `$wp_filter` when it isn't, relying on the `$wp_filter` bootstrap code at the top of `plugin.php` to handle conversion.
