Gary Pendergast 56c162fbc9 Coding Standards: Upgrade WPCS to 1.0.0
WPCS 1.0.0 includes a bunch of new auto-fixers, which drops the number of coding standards issues across WordPress significantly. Prior to running the auto-fixers, there were 15,312 issues detected. With this commit, we now drop to 4,769 issues.

This change includes three notable additions:
- Multiline function calls must now put each parameter on a new line.
- Auto-formatting files is now part of the `grunt precommit` script. 
- Auto-fixable coding standards issues will now cause Travis failures.

Fixes #44600.

Joe McGill 0569c6219e Post Thumbnails: Prevent post thumbnail previews from spilling into other images.
After [38118], when previewing a page with a secondary loop, all post
thumbnails would be filtered to display the post thumbnail for the
page being previewed. This ensures `_wp_preview_post_thumbnail_filter()`
is only applied if the `$post_id` of the post meta being filtered is
equal to the post or page being previewed.

Joe McGill 3dbba0fff3 Post Thumbnails: Only update featured images when saving a post.
Previously, changing the post thumbnail of a published post in the edit screen
would immediately apply the change, rather than waiting for the post to be
saved before applying the update. This could lead to someone unintentionally
editing the post thumbnail on a published post, and made it impossible to
preview changes to post thumbnails on published posts before saving the change.

This introduces a new Ajax handler, `wp_ajax_get_post_thumbnail_html()` to
retrieve the HTML for the post thumbnail meta box without updating the post
meta value for `_thumbnail_id`. It also allows post thumbnail changes to be
previewed by passing the `_thumbnail_id` as a query variable to the preview
screen and adding a new filter, `_wp_preview_post_thumbnail_filter()`, which
gets applied to `get_post_metadata` during the post preview process.

Drew Jaynes f8657d5890 Remove redundant and erroneous `@uses` tag from most core inline documentation.
Per our inline documentation standards, no further use of the `@uses` tag is recommended as used and used-by relationships can be derived through other means. This removes most uses of the tag in core documentation, with remaining tags to be converted to `@global` or `@see` as they apply.

Fixes #30191.

John Blackbourn a866a7192f Introduce some actions and filters which aid plugins in revisioning post meta.
* `wp_save_post_revision_post_has_changed` filter which can be used to determine if a post has been changed, and therefore if a revision should be created for a post.
 * `wp_get_revision_ui_diff` filter which can be used to filter the fields displayed in the post revision diff UI.
 * `wp_creating_autosave` action which is fired just before an autosave is created.

See #20564.
Props mattheu, adamsilverstein.

Sergey Biryukov fdaa694ac7 Remove unnecessary array_reverse() from wp_get_post_revisions().
WP_Query properly handles multiple 'orderby' values since [28541].

Scott Taylor 333083debe Apply `order` to each passed value for `orderby` in `WP_Query`:
* Since `orderby` in `WP_Query` can accept space-delimited sets, yet only one `order` value: when multiple values are passed (and `DESC` is the order), the default sort order `ASC` is being applied to all values before the last in the set.
* There is a unit test that sporadically fails since 3.6 in `tests/post/revision` due to multiple posts having the same `post_date` from being added so rapidly
* When ordering revisions in `wp_get_post_revisions()`, order by `post_date ID`
* Change the `order` value in `wp_get_post_revisions()` to `ASC`. This will produce SQL like: `ORDER BY $wpdb->posts.post_date ASC, $wpdb->posts.ID ASC`. Previously, this would have produced SQL like: `ORDER BY $wpdb->posts.post_date DESC`, and with the addition of ` ID`: `ORDER BY $wpdb->posts.post_date ASC, $wpdb->posts.ID DESC`. Clearly, wrong. The original SQL produced: `ORDER BY $wpdb->posts.post_date DESC`. As such, return the reversions in reverse order using `array_reverse()`. Not doing so would break "Preview Changes."
* Add unit tests to assert that all of this works.
* All existing unit tests pass with the change to ordering multiple `orderby`s in `WP_Query`.
* In the future, we should support independent `order` for each `orderby`, see #17065.
