New functions in `media.php`:
* `wp_get_attachment_image_srcset_array()` - Returns an array of image candidate string data used to build a `srcset` value for an attachment given an `$attachement_id` and `$size`.
* `wp_get_attachment_image_srcset()` - Returns the `srcset` value for an attachment given an `$attachement_id` and `$size`.
* `wp_get_attachment_image_sizes()` - Returns the `sizes` value for an attachment given an `$attachement_id` and `$size` and optional arguments used to alter its output.
* `wp_make_content_images_responsive()` - A display filter for adding `srcset` and `sizes` to images embedded in content.
* `wp_img_add_srcset_and_sizes()` - A utility function used by `wp_make_content_images_responsive()` to add `srcset` and `sizes` to a single `<img>` element.
Modifies existing core functions:
* Modify `wp_get_attachment_image()` so the HTML returned for an image includes `srcset` and `sizes`.
* Modify `get_media_embedded_in_content()` (sup, 3.6 leftover) by adding `<img>` to the list of accepted tags that can be matched in content. This is used in `wp_make_content_images_responsive()` to find all of the images embedded in content before passing them off to `wp_img_add_srcset_and_sizes()`.
Tests:
* Add a new factory method to `WP_UnitTest_Factory_For_Attachment` named `create_upload_object()`
* Adds unit tests
* Updates unit tests

* Tokenize newlines in `WP_Embed::autoembed()` before running `->autoembed_callback()`
* Tokenize newlines with placeholders in `wpautop()`
* Introduce `wp_html_split()` to DRY the RegEx from `wp_replace_in_html_tags()` and `do_shortcodes_in_html_tags()`
Adds unit tests.

YouTube recently changed its oEmbed endpoint so that the iframe markup always
contains an HTTPS URL, regardless of the scheme of the video URL originally
requested. This changeset fixes the corresponding unit test.
Fixes#32260.

Make sure the caption is always set if found. Previously, if the caption was less than 80 characters, only the Title field would be set.

* Check `! empty( $postarr['file'] )` before calling `update_attached_file()`
* Add a unit test: `test_update_attachment_fields()`
* Run the same logic for empty `guid` for attachments that always ran in `wp_insert_post()`, as per #18310. This fixes a unit test that would have broken when this ticket was marked closed.
* Updated the unit test in `Tests_Media::test_wp_prepare_attachment_for_js()` to account for `url` no longer being empty

* Remove duplicated code for deprecated function notice suppression
* Add support in `WP_UnitTestCase` setUp/tearDown methods for `$deprecated_functions` fixture if the extending class has added it
* Add a `$deprecated_functions` fixture to each extending class that needs it
To use this fixture, add something to your Test Case class like so:
`protected $deprecated_functions = array( 'get_theme', 'get_themes', 'get_theme_data', 'get_current_theme' );`
See #25282.
