The `term_exists()` check is not needed because of existing dupe
checks in `wp_insert_term()`. Furthermore, `term_exists()` conflates
term names and sanitized slugs, so incorrectly marks terms like
'C' and 'C+' as duplicates of one another.

This addresses a major bug. Incorrectly setting the `$content_width` causes media embeds to end up with the wrong aspect ratio, among other issues. This fix uses `template_redirect`, to ensure conditional theme tags can be used. It also defines a default value at `after_theme_setup` so that plugins have something to work with at `init`.

When plugins don't disable the `backupGlobals` PHPUnit option in their own tests, `$wpdb` is backed up and restored between classes of tests. The serialisation process used for this broke the database connection. This previously wasn't a problem, as it was reconnecting before each test.
[38398] introduced some changes that required the connection to be available in `setUpBeforeClass()`, earlier than in was previously reconnecting. This didn't cause warnings in Core, but it did cause warnings for plugins that don't disable the `backupGlobals` option.
The database connection now reconnects in `setUpBeforeClass()`. This change also fixes a few Core tests that weren't calling `parent::setUpBeforeClass()` or `parent::tearDown()` correctly.

Also fix logic for `focus-control-for-setting` handler to focus on the first control (lowest `priority` value) associated with a given setting instead of the last control encountered when iterating over all controls, as this ensures the first control in a `nav_menu` section is focused rather than the last one.

The `rest_{$taxonomy}_collection_params` filter in 4.7 is incorrectly using
single quotes instead of double quotes, which means it is not working correctly
as a dynamic filter. This fixes the quotes around the filter name, and also
updates the docblocks for the other 3 similar filters for better conformance to
the documentation standards.

If `add_theme_support( 'post-formats' )` is called with no additional
arguments, then `get_theme_support( 'post-formats' )` returns `true` rather
than an array of supported formats. Avoid generating PHP warnings in this

Correct setup for the `model` attribute of `wp.api.collections` objects. Set the collection model as a function that returns a new model of the underlying type, instead of setting it as the model prototype. Fixes an issue where models for fetched collections weren't set up properly and didn't have the expected mixin methods such as `getCategories` available.

In [38625], the functionality to search for attachments by filename was added
via the `posts_clauses` filter and the `_filter_query_attachment_filenames()`
function. This moves `_filter_query_attachment_filenames()` from
`wp-admin/includes/post.php` to `wp-includes/post.php` so that it can be
applied in the same manner in the REST API media endpoint.

It's fairly common for clients to send `Content-Type: application/json` with an
empty body. While technically not valid JSON, we've historically supported
this behaviour, so it shouldn't cause an error.

`get_category_link()` is a wrapper for `get_term_link()`. Using the
unwrapped function makes more sense semantically (it's taxonomy-
agnostic) and it's also more parsimonious (the `WP_Error` check in
`get_category_link()` is redundant with similar checks just before
in `get_term_link()`).

Site administrators should not be able to remove themselves from a site. This moves the enforcement of this rule from `wp-admin/users.php` to `remove_user_from_blog()` via the `remove_user` capability, which furthermore allows us to get rid of two additional clauses and their `is_super_admin()` checks in `wp-admin/users.php`. A unit test for the new behavior has been added.

Previously an option containing an object would trigger an SQL `UPDATE` on all calls to `update_option`, even if the old and new values were identical. This was due to the old and new values having differing resource IDs.
This change compares the old and new values as serialized data to remove the resource ID from the comparison.

The logic in WP_REST_Request->sanitize_params() added in [39091] did not account for `null` or `false` being the sanitization_callback preventing overriding `rest_parse_request_arg()`. This fixes that oversight, allowing the built in sanitization function to be bypassed. See #38593.
