Fixes bug where an invalid Last-Modified value would be returned in feed requests for sites that had 0 items to return. Comment or post feeds will now return the current timestamp as the Last-Modified header value. Example: a request for the comments feed for a site without any comments.
Replaced use of the local static variable `$cache_lastcommentmodified` to store the modified date in `get_lastcommentmodified()` with the Object Cache API. The `get_lastcommentmodified()` function returns early if there is a cached value and returns `false` if there where no comments found. Introduced `_clear_modified_cache_on_transition_comment_status()` to flush the `lastcommentmodified` cache key when a comment enters or leaves approval status. In `get_lastpostmodified()` return early if there is a cached value and return `false` if there are no posts found.

This brings the custom colors CSS in line with the stylesheet. Some selectors were missing since many changes occurred in `style.css` a few days before the original merge to Core.

Previously, if an invalid post status was assigned to a media object, the object would be returned with an unchanged status. After [38911], an error response is returned.
The assertion in test_get_items_invalid_status_param_is_discarded() needs to be updated to account for the expected error response. The test name has been changed to `test_get_items_invalid_status_param_is_error_response()`.

Pass `false` as the `$passed_default` value when the `default_option_{$option}` filter is applied in `update_option` as no default is ever passed.
This resolves an error in tests where the 3rd parameter is not available to `filter_default_option()`.

Add a `default` argument to `register_setting` that will be used an the default option value viet `get_option()` in the event of no other option being specified. This means (if chosen) developers can define their default once via `register_option` and not have to duplicate the value every time they make a call to `get_option()`.

`WP_DEFAULT_THEME` was being defined in the wrong location.
Also, if WordPress has the original "default" theme installed, ensure that our test theme overrides it.

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`.

This ability was previously added to nav menus via the available page items panel. The "Add New Page" button only appears when the `allow_addition` control param is supplied as `true`. Code is adapted from the Customize Posts feature plugin.

An empty string causes some browsers to use the current URL as the `href`. When using `history.replaceState()` Chrome will re-fetch the favicon with each call, meaning that `customize.php` gets hit with wasted requests which tax the server.

Previously we ensured that the entry points to WordPress were parsable by PHP4 in order to display a friendly not-supported-php error message.
However, for the last two years the main entry points have not actually parsed, and we've only added extra parse errors since it last worked in 3.9, so it's time we just remove this 'feature'.
The PHP version checks are still there for PHP 5.0/5.1, and so it's inplace when we eventually drop PHP 5.2 support.

There are a handful of places where we don't check that the XML functions exist before we use them. Ubuntu's PHP 7 packages don't include PHP-XML by default, increasing the chance of this causing issues.

On the Header Image section, the previously uploaded images disappeared off-screen
when using the keyboard to navigate and the remove "X" button got keyboard focus.
Changing the off-screen CSS technique used for the "X" buttons fixes it.
- improves the focus style on the previously uploaded and suggested images
- removes a `tabindex="0"` attribute from the current header image

- changes the "X" links in buttons, improves their color contrast ratio and focus style
- adds screen reader text "Remove item: + tagname"
- uses `wp.a11y.speak()` to give screen reader users feedback when adding/removing tags
- makes the `tagcloud-link` toggle a button, with an `aria-expanded` attribute to indicate the tag cloud collapsed/expanded state
- changes colors for the autocomplete highlighted option in order to have a better color contrast ratio
- reduces the font size for the autocomplete on Press This
- removes CSS related to the old `suggest.js` from Press This
