Switching the available roles and the current user's capabilities no longer happens in `switch_to_blog()` and `restore_current_blog()`, instead it has been moved to a new function `wp_switch_roles_and_user()` which is hooked into the site switching process. This allows to improve performance by temporarily unhooking the function when roles and capabilities do not need to be switched.
This change ensures that switching available roles now works closer to switching user capabilities, particularly the changes in [41624]. A new `WP_Roles::for_site( $site_id )` method has been introduced, and the `WP_Roles::_init()` method has been deprecated. It is furthermore possible to retrieve the site ID for which the available roles are currently initialized through a new `WP_Roles::get_site_id()`.

While it has always been possible to initialize a user's roles and capabilities for another site than the current one in a multisite, the actual roles available were not switched prior to this change, possibly causing invalid roles to show up or actually valid capabilities not being available.
In order to fix this bug in a clean way, relevant parts of the `WP_User` class have been refactored. The ID of the site for which capabilities are currently initialized are now stored in a private property `WP_User::$site_id`. The `WP_User::for_blog( $blog_id )` and `WP_User::_init_caps( $cap_key )` methods have been deprecated in favor of `WP_User::for_site( $site_id )`. In addition, a new method `WP_User::get_site_id()` has been introduced to retrieve the site ID for which the user's capabilities are currently initialized.

Given the new WordPress browsers support policy, the `screen-reader-text` css
class used in the admin can be updated to use modern CSS and correct syntax. See
https://github.com/wpaccessibility/a11ythemepatterns/blob/master/read-more-links/style.css
Worth noting the `clip` property is deprecated and kept for IE11 and Edge.
- uses `clip-path` for modern browsers
- keeps `clip` for old browsers and update its value to a correct syntax
- resets `clip-path` to `none` where the class is used to dynamically reveal elements
- removes an old rule that made `screen-reader-text` completely invisible in the help tabs `#screen-meta`
- standardizes the rule across CSS files

- uses button elements for the toggles
- uses `aria-expanded` on the toggles to communicate to assistive technologies the panels expanded/collapsed state
- adds the "circular focus" style to the toggles to give users a clear indication of the currently focused element
- standardizes CSS class names to `.toggle-indicator` and `.handlediv` as these names are already used across the admin for similar controls

Calling the `count_users()` function is expensive, regardless of the counting strategy that's used, and it gets
slower the more users there are on a site. In order to speed up the Users screen in the admin area, calling
`count_users()` can be avoided entirely while still displaying the total count for users.
This introduces some new functions:
* `wp_is_large_user_count()`
* `wp_get_active_user_count()`
* `wp_update_active_user_count()`
A corresponding `wp_is_large_user_count` filter is also introduced.

* Autosaved changes made on top of `auto-draft` changesets get written on top of the `auto-draft` itself, similar to how autosaves for posts will overwrite post drafts.
* Autosaved changes made to saved changesets (e.g. `draft`, `future`) will be placed into an autosave revision for that changeset and that user.
* Opening the Customizer will now prompt the user to restore their most recent auto-draft changeset; if notification is dismissed or ignored then the auto-draft will be marked as dismissed and will not be prompted to user in a notification again.
* Customizer will no longer automatically supply the `changeset_uuid` param in the `customize.php` URL when branching changesets are not active.
* If user closes Customizer explicitly via clicking on X link, then autosave auto-draft/autosave will be dismissed so as to not be prompted again.
* If there is a changeset already saved as a `draft` or `future` (UI is forthcoming) then this changeset will now be autoloaded for the user to keep making additional changes. This is the linear model for changesets.
* To restore the previous behavior of the Customizer where each session started a new changeset, regardless of whether or not there was an existing changeset saved, there is now a `customize_changeset_branching` hook which can be filtered to return `true`.
* `wp.customize.requestChangesetUpdate()` now supports a second with options including `autosave`, `title`, and `date`.
* The window `blur` event for `customize.php` has been replaced with a `visibilitychange` event to reduce autosave requests when clicking into preview window.
* Adds `autosaved` and `branching` args to `WP_Customize_Manager`.
* The `changeset_uuid` param for `WP_Customize_Manager` is extended to recognize a `false` value which causes the Customizer to defer identifying the UUID until `after_setup_theme` in the new `WP_Customize_Manager::establish_loaded_changeset()` method.
* A new `customize_autosaved` query parameter can now be supplied which is passed into the `autosaved` arg in `WP_Customize_Manager`; this option is an opt-in to source data from the autosave revision, allowing a user to restore autosaved changes.

* Galleries are managed in the widget in the same way they are managed in the post editor, both using the media manager.
* Gallery widget is merged from the Core Media Widgets v0.2.0 feature plugin and it extends `WP_Widget_Media` in the same way as is done for image, audio, and video widgets.
* Model syncing logic is updated to support booleans and arrays (of integers).
* Placeholder areas in media widgets are now clickable shortcuts for selecting media.
* Image widget placeholder is updated to match gallery widget where clicking preview is shortcut for editing media.

- properly labels all the code editor areas (Theme/Plugin, Custom HTML widget, Additional CSS), whether CodeMirror is enabled or disabled
- adds `role="textbox"` and `aria-multiline="true"` to the CodeMirror editing area to allow assistive technologies properly identify it as a textarea
- standardizes the "keyboard trap" help text across the admin and keeps it as a list for better readability
- use the Help text elements as target for `aria-describedby`, to make screen readers read out the help text when focusing the editors
- fixes the `aria-expanded` attribute usage in the Customizer "Additional CSS" help toggle
- moves focus to the CodeMirror editing area when clicking on the associated label
- in the Plugin editor screen: changes a `<big>` element to `<h2>` for better semantics and consistency with the Theme editor screen
- also, removes a few textdomain leftovers, see `better-code-editing` and `default`
