Felix Arntz a9b8f70682 Multisite: Establish `clean_blog_cache()` as a replacement for `refresh_blog_details()`.
Going forward, `clean_blog_cache()` is recommended to be used instead of `refresh_blog_details()`. It has been adjusted to match the functionality of the latter, with the exception that it always requires a site ID or object to be passed. The `refresh_blog_details` action has been deprecated in favor of the `clean_site_cache` action. The function itself is not formally deprecated at this point, but will likely be in the near future.

Props spacedmonkey.
Fixes #40201.

John Blackbourn 1e1a48aaa0 Embeds: Remove the external oEmbed tests for YouTube.
These tests no longer test anything that WordPress core has control over. YouTube now serves everything
over HTTPS by default, so the tests for #23149 will always pass, and the tests for #32714 aren't testing
anything that core has control over.

Tests for the responses from oEmbed providers has been attempted and reverted in #32360.

Gary Pendergast a7a57df525 Emoji: Bring Twemoji compatibility to PHP.
This was previously attempted in [41043], which unfortunately had severe performance issues, the regex it used was fatally slow on long posts.

This version now uses an array of all emoji that Twemoji supports, which maintains the accuracy of [41043], while being the same speed or only a few ms slower than the code prior to [41043].

As with [41043], the `grunt precommit:emoji` task detects when `twemoji.js` has changed, and regenerates the array.

Jeremy Felt 7e190e496b Multisite: Use `%s` when building query for `archived` sites in `WP_Site_Query`.
In [25548], the `archived` column in `wp_blogs` was changed from `ENUM` to `TINYINT` to match other status fields. When `WP_Site_Query` was written later, it used `%d` as a placeholder when formatting the archived status.

It is possible that this query will fail for any installations that did not update the schema for `wp_blogs` as only single quoted values are accepted for the `ENUM` type. In this case, `'0'` or `'1'` rather than `0` or `1`.

We can work around this and support both `ENUM` and `TINYINT` in the query by using the `%s` placeholder and casting the value with `absint()`.

Konstantin Obenland 1e6810e433 Widgets: Revert format of `sidebars_widgets`.
Restores the data format of the `sidebars_widgets` theme mod to its pre [41555]
format. It can trigger PHP warnings after switching themes if that mod has not
been removed previously.

Fixes #39693.

Jeremy Felt 5ccf8eebb7 Multisite: Deprecate `is_user_option_local()`.
`is_user_option_local()` was added during MU development and used for a handful of changesets before the code using it was removed again. It has not been used by MU or core since nor is it widely used elsewhere.

Fixes #41697.

Weston Ruter 728e44ab5a Customize: Add infrastructure for trashing/reverting of unpublished changes; introduce full-screen `OverlayNotification` for trashing and theme install/preview.
* Introduce a new `wp.customize.previewer.trash()` JS API to trash the current changeset, along with logic to `WP_Customize_Manager` to handle deleting changeset drafts.
* Add `trashing` to `wp.customize.state` which is then used to update the UI.
* UI for trashing is pending design feedback. One possibility is to add a new trash button to Publish Settings section that invokes `wp.customize.previewer.trash()`.
* Improve logic for managing the visibility and disabled states for publish buttons.
* Prevent attempting `requestChangesetUpdate` while processing and bump processing while doing `save`.
* Update `changeset_date` state only if sent in save response.
* Merge `ThemesSection#loadThemePreview()` into `ThemesPanel#loadThemePreview()`.
* Remove unused `autosaved` state.
* Start autosaving and prompting at beforeunload after a change first happens. This is key for theme previews since even if a user did not make any changes, there were still dirty settings which would get stored in an auto-draft unexpectedly.
* Allow `Notification` to accept additional `classes` to be added to `container`.
* Introduce `OverlayNotification` and use for theme installing, previewing, and trashing. Such overlay notifications take over the entire window.
