1b46470b75 Docs: Link to the "Conditional Tags" article in the Theme Developer Handbook from the descriptions for a variety of core conditional tag functions. 
These notations largely serve to direct consumers (of both the source and the parsed code reference) to extended information on individual and related conditional tags throughout WordPress. The changeset also standardizes corresponding DocBlock summaries to use third-person singular verbs.

Notations been added for the following functions:

* comments_open()
* email exists()
* has_excerpt()
* has_post_thumbnail()
* has_tag()
* in_category()
* in_the_loop()
* is_404()

a39d599adf Database: Restore numbered placeholders in wpdb::prepare(). 
[41496] removed support for numbered placeholders in queries send through `wpdb::prepare()`, which, despite being undocumented, were quite commonly used.

This change restores support for numbered placeholders (as well as a subset of placeholder formatting), while also adding extra checks to ensure the correct number of arguments are being passed to `wpdb::prepare()`, given the number of placeholders.

f3a59f8632 Theme starter content: Add support for featured images and page templates. 
Featured image support means that attachments can now be imported. Media can be sideloaded from within theme or plugin directories. Like other posts, attachments are auto-drafts until customizer changes are published, and are not duplicated when they already exist in the customized state. Attachment IDs can be used for any number of purposes, much like post IDs. Twenty Seventeen now includes 3 images used as featured images to best showcase the multi-section homepage setup.

As featured image IDs are stored in post meta, it also made sense to add support for page templates. Twenty Seventeen does not include any such templates, but the functionality can be quite important for displaying themes to their best effect.

a9516abb54 Posts, Post Types: Add support for post type templates. 
WordPress has supported custom page templates for over 12 years, allowing developers to create various layouts for specific pages.
While this feature is very helpful, it has always been limited to the 'page' post type and not was not available to other post types.

By opening up the page template functionality to all post types, we continue to improve the template hierarchy's flexibility.

In addition to the `Template Name` file header, the post types supported by a template can be specified using `Template Post Type: post, foo, bar`.
When at least one template exists for a post type, the 'Post Attributes' meta box will be displayed in the back end, without the need to add post type support for `'page-attributes'`. 'Post Attributes' can be customized per post type using the `'attributes'` label when registering a post type.

ea3b41d8e3 Feeds: Always return a valid timestamp for the Last-Modified header of comment or post feeds. 
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.

a8aa7b0ca2 Cache API: introduce wp_cache_get_last_changed to improve DRY 
One thing fairly common to the cache groups is a block of code to look to see when the cache was last changed, and if there isn't one, to set it for the current microtime(). It appears in 8 different places in core. This adds a new helper `wp_cache_get_last_changed` to DRY things up a bit.

Since `wp-includes/cache.php` isn't guaranteed to be loaded, this new function is in `wp-includes/functions.php`

Props spacedmonkey, desrosj.
Fixes #37464.

ede099a704 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!"

76226c9b41 Customize: Introduce custom CSS for extending theme styles. 
* Custom CSS is associated with a given theme and is displayed in an inline `style` element at the `wp_head` hook after the `wp_print_styles` is called so that it overrides any enqueued stylesheets.
* A `wp_get_custom_css()` function is used for accessing the CSS associated with the current theme (or another theme) and a `wp_get_custom_css` filter for manipulating it.
* CSS is managed in customizer via a new "Additional CSS" section with a single `textarea` control. 
* `WP_Customize_Section::$description_hidden` is introduced for hiding extended descriptions in customizer sections behind a help toggle as done with panels.
* CSS is stored in a `custom_css` post type with the theme (stylesheet) slug as the `post_name`.
* `WP_Customize_Custom_CSS_Setting` is introduced to handle validation of CSS, previewing, and persisting the CSS to the `custom_css` post type.
* The `custom_css` setting is tied to a new `unfiltered_css` capability which maps to `unfiltered_html` by default.
* Escaping the message in the notification template is removed to allow markup (`code` tags) to be rendered.
