Sergey Biryukov 47ed56f38f Code Modernization: Replace `dirname( __FILE__ )` calls with `__DIR__` magic constant.
This avoids the performance overhead of the function call every time `dirname( __FILE__ )` was used instead of `__DIR__`.

This commit also includes:

* Removing unnecessary parentheses from `include`/`require` statements. These are language constructs, not function calls.
* Replacing `include` statements for several files with `require_once`, for consistency:
 * `wp-admin/admin-header.php`
 * `wp-admin/admin-footer.php`
 * `wp-includes/version.php`

Drew Jaynes 1fb8cbe8de Docs: Don't reference non-existent hooks inline in the DocBlock descriptions for the following template functions:
* `get_index_template()`
* `get_404_template()`
* `get_author_template()`
* `get_category_template()`
* `get_tag_template()`
* `get_taxonomy_template()`
* `get_date_template()`

* `get_page_template()`
* `get_search_template()`
* `get_single_template()`
* `get_embed_template()`
* `get_singular_template()`
* `get_attachment_template()`

As mentioned when these dynamic hook references were originally fixed in [33274], we can't link to non-existent hooks inline because the Code Reference auto-linker won't pick up on the dynamic-ness of the hook, it'll just try to link to a hook reference that doesn't exist. In these cases, we need to be generic and provide context for the value of `$type`.

See [38418] for where the original fix was reversed. See this changeset for reversing the reversal.

Pascal Birchler 81a26f6900 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.

The position of this template within the hierarchy is of so little use that zero themes in the WordPress.org theme directory make use of it. It's second only to `index.php` in the hierarchy, meaning that any archive template such as `category.php` or `archive.php` will be chosen before it.

John Blackbourn 9e1542b9ec Themes: Make the template hierarchy for a given template type filterable.
This introduces a `{$type}_template_hierarchy` filter that allows the hierarchy of candidate template filenames for a given template type to be filtered.

This allows the hierarchy to be added to or altered completely without resorting to re-building the hierarchy from scratch within the `template_include` filter, which is common and prone to conflicts between plugins and prone to getting out of sync with core's hierarchy.

John Blackbourn a027edc277 Comments: The year is 2003. Permalinks are a new thing and everyone's using Blogger. It's a time when opening a modal window in JavaScript to view a section of a website is not a completely weird thing, although many users get annoyed by it. b2 has recently become WordPress, and with it comes a bunch of functionality that will become stale over the next decade, remnants of simpler times.
Twelve years later, after no fewer than three themes have intentionally implemented popup comments in their functionality, before being abandoned for at least the last six years, we've reached a time where we can put this era behind us. A time when we can remove comment popup functionality from WordPress.

If this breaks the internet, I'll eat my hat.

Drew Jaynes f7f4a97d07 Docs: Clarify the hook docs for the `{$type}_template` hook to mention that non-alphanumeric characters delimiting words will also be removed from the passed `$type` parameter.
Also remove a now-unnecessary inline `@see` tag from the return description.

See #32246. See #32989.

Aaron Jorbin 4b7ce555d0 Add singular.php to template hierarchy
Singular is the only template context conditional that lacks a corresponding template. This allows some themes to simplify.

Fixes #22314.

Scott Taylor fe6b5983df In PHP 5.0.0, `is_a()` became deprecated in favour of the `instanceof` operator. Calling `is_a()` would result in an `E_STRICT` warning.
In PHP 5.3.0, `is_a()` is no longer deprecated, and will therefore no longer throw `E_STRICT` warnings.

To avoid warnings in PHP < 5.3.0, convert all `is_a()` calls to `$var instanceof WP_Class` calls.

`instanceof` does not throw any error if the variable being tested is not an object, it simply returns `false`.

Scott Taylor 60b0cd7943 The keyword `elseif` should be used instead of `else if` so that all control keywords look like single words.
This was a mess, is now standardized across the codebase, except for a few 3rd-party libs.
