Bootstrap/Load: Make handling the `/favicon.ico` requests more flexible.
Previously, `wp_favicon_request()` was introduced in [13205] to avoid a performance hit of serving a full 404 page on every favicon request.
While working as intended, that implementation did not provide a way for theme or plugin authors to manage the behavior of favicon requests.
This changeset implements the following logic (only applied if WordPress is installed in the root directory):
* If there is a Site Icon set in Customizer, redirect `/favicon.ico` requests to that icon.
* Otherwise, use the WordPress logo as a default icon.
* If a physical `/favicon.ico` file exists, do nothing, let the server handle the request.
Handling `/favicon.ico` is now more consistent with handling `/robots.txt` requests.
New functions and hooks:
* Introduce `is_favicon()` conditional tag to complement `is_robots()`.
* Introduce `do_favicon` action to complement `do_robots` and use it in template loader.
* Introduce `do_favicon()` function, hooked to the above action by default, to complement `do_robots()`.
* Introduce `do_faviconico` action to complement `do_robotstxt`, for plugins to override the default behavior.
* Mark `wp_favicon_request()` as deprecated in favor of `do_favicon()`.

Use `wp_installing()` instead of `WP_INSTALLING` constant.
The `WP_INSTALLING` constant is a flag that WordPress sets in a number of
places, telling the system that options should be fetched directly from the
database instead of from the cache, that WP should not ping wordpress.org for
updates, that the normal "not installed" checks should be bypassed, and so on.
A constant is generally necessary for this purpose, because the flag is
typically set before the WP bootstrap, meaning that WP functions are not yet
available. However, it is possible - notably, during `wpmu_create_blog()` -
for the "installing" flag to be set after WP has already loaded. In these
cases, `WP_INSTALLING` would be set for the remainder of the process, since
there's no way to change a constant once it's defined. This, in turn, polluted
later function calls that ought to have been outside the scope of site
creation, particularly the non-caching of option data. The problem was
particularly evident in the case of the automated tests, where `WP_INSTALLING`
was set the first time a site was created, and remained set for the rest of the
suite.
The new `wp_installing()` function allows developers to fetch the current
installation status (when called without any arguments) or to set the
installation status (when called with a boolean `true` or `false`). Use of
the `WP_INSTALLING` constant is still supported; `wp_installing()` will default
to `true` if the constant is defined during the bootstrap.

If reinstalling WordPress, there is a condition where tables would exist in the database. Ensures that when that is the case, the install process can carry along without issue.

Drop Open Sans in the admin in favor of system fonts.
Rejoice, for your admins will feel more native to your surrounding computing environment and likely load faster, especially when offline, as they no longer have to talk to The Google Overlord.
At the time of introduction in 3.8, there were not good system fonts common to all platforms at the time. In the years since, Windows, Android, OS X, iOS, Firefox OS, and various flavors of Linux have all gotten their own (good) system UI fonts.
There will definitely be visual bugs, mainly around alignment and spacing; these should be documented and reported on the ticket and fixed more atomically so that our current and future selves have a better understanding of what happened and why.
The style remains registered, as it is almost certainly in use by themes and plugins.

Customize: Introduce starter content and site freshness state.
A theme can opt-in for tailored starter content to apply to the customizer when previewing the theme on a fresh install, when `fresh_site` is at its initial `1` value. Starter content is staged in the customizer and does not go live unless the changes are published. Initial starter content is added to Twenty Seventeen.
* The `fresh_site` flag is cleared when a published post or page is saved, when widgets are modified, or when the customizer state is saved.
* Starter content is registered via `starter-content` theme support, where the argument is an array containing `widgets`, `posts`, `nav_menus`, `options`, and `theme_mods`. Posts/pages in starter content are created with the `auto-draft` status, re-using the page/post stubs feature added to nav menus and the static front page controls.
* A `get_theme_starter_content` filter allows for plugins to extend a theme's starter content.
* Starter content in themes can/should re-use existing starter content items in core by using named placeholders.
* Import theme starter content into customized state when fresh site.
* Prevent original_title differences from causing refreshes if title is present.
* Ensure nav menu item url is set according to object when previewing.
* Make sure initial saved state is false if there are dirty settings without an existing changeset.
* Ensure dirty settings are cleaned upon changeset publishing.

REST API: Introduce the Content API endpoints.
REST API endpoints for your WordPress content. These endpoints provide machine-readable external access to your WordPress site with a clear, standards-driven interface, allowing new and innovative apps for interacting with your site. These endpoints support all of the following:
- Posts: Read and write access to all post data, for all types of post-based data, including pages and media.
- Comments: Read and write access to all comment data. This includes pingbacks and trackbacks.
- Terms: Read and write access to all term data.
- Users: Read and write access to all user data. This includes public access to some data for post authors.
- Meta: Read and write access to metadata for posts, comments, terms, and users, on an opt-in basis from plugins.
- Settings: Read and write access to settings, on an opt-in basis from plugins and core. This enables API management of key site content values that are technically stored in options, such as site title and byline.
Love your REST API, WordPress! The infrastructure says, "Let's do lunch!" but the content API endpoints say, "You're paying!"

I18N: Improve translator comments.
* Add missing translator comments.
* Fix placement of some translator comments. Translator comments should be on the line directly above the line containing the translation function call for optimal compatibility with various `.pot` file generation tools. The CS auto-fixing, which changed some inconsistent function calls to multi-line function calls, is part of the reason why this was no longer the case for a select group of translator comments.
Includes minor code layout fixes.
Polyglots, rejoice! All WordPress core files now have translator comments for all strings with placeholders!

Privacy: Rename exports folder to avoid deleting other files.
Previously, personal data exports were stored in `wp-content/uploads/exports`, which is generic enough that it's likely there are existing folders with that name, either created by plugins or manually by administrators. If that folder were reused by Core, then `wp_privacy_delete_old_export_files()` would delete all of the existing files inside it, which is almost certainly not what the site owner wants or expects.
To avoid that, the folder is being renamed to include a specific reference to Core, and a more verbose description of its purpose. With those factored in, it's very unlikely that there will be any conflicts with existing folders.
The `wp_privacy_exports_dir()` and `wp_privacy_exports_url()` functions were introduced to provide a canonical source for the location, and the `wp_privacy_exports_dir` and `wp_privacy_exports_url` filters were introduced to allow plugins to customize it.

Privacy: Rename exports folder to avoid deleting other files.
Previously, personal data exports were stored in `wp-content/uploads/exports`, which is generic enough that it's likely there are existing folders with that name, either created by plugins or manually by administrators. If that folder were reused by Core, then `wp_privacy_delete_old_export_files()` would delete all of the existing files inside it, which is almost certainly not what the site owner wants or expects.
To avoid that, the folder is being renamed to include a specific reference to Core, and a more verbose description of its purpose. With those factored in, it's very unlikely that there will be any conflicts with existing folders.
The `wp_privacy_exports_dir()` and `wp_privacy_exports_url()` functions were introduced to provide a canonical source for the location, and the `wp_privacy_exports_dir` and `wp_privacy_exports_url` filters were introduced to allow plugins to customize it.

General: Make Update PHP notice link customizable.
After [42832], [42891] and [43006], this changeset refines the core notice informing about an outdated PHP version:
* The link to the Update PHP information page can now be adjusted using either a `WP_UPDATE_PHP_URL` environment variable, or a new `wp_update_php_url` filter.
* If that URL is different from the default one that points to https://wordpress.org/support/update-php/ or its localized equivalent, a note indicates that the linked resource has not been provided by WordPress itself, and the default URL is still linked to as an additional resource.
* The URL for the default information page has been updated to use the slug `update-php` instead of `upgrade-php`.
* `@since` annotations have been updated.
Going forward, admin areas that display information related to the PHP version should use the new function `wp_get_update_php_url()`.
