For the past 6 years, WordPress has operated as an oEmbed consumer, allowing users to easily embed content from other sites. By adding oEmbed provider support, this allows any oEmbed consumer to embed posts from WordPress sites.
In addition to creating an oEmbed provider, WordPress' oEmbed consumer code has been enhanced to work with any site that provides oEmbed data (as long as it matches some strict security rules), and provides a preview from within the post editor.
For security, embeds appear within a sandboxed iframe - the iframe content is a template that can be styled or replaced entirely by the theme on the provider site.

Fixes#32522.

Awesome rewrite bug: the `page` query var was being set to `'/4'` in `$wp`. When cast to `int`, it returns `0` (Bless you, PHP). `WP_Query` calls `trim( $page, '/' )` when setting its own query var. The few places that were checking `page` before posts were queried now have sanity checks, so that these changes work without flushing rewrites.
Adds/updates unit tests.

The rewrite functions have all kinds of cross-dependencies (like `WP_Query`), so loading the file by itself would have been bizarre (and still is).
Creates:
`rewrite-constants.php`
`rewrite-functions.php`
`class-wp-rewrite.php`
`rewrite.php` contains only top-level code. Class file only contains the class. Functions file only contains functions.
