`wpautop()` considers double line breaks to be the separator between block level HTML elements. By adding two line breaks before a block element, this allows us to process the text before a block element correctly.

[38179] added support for the rainbow flag to core, but platform compatibility is a bit strange, because the flag was defined out of sync with the usual Unicode release cycle. For example Android N supports all Unicode 9.0 emoji, but doesn't support the rainbow flag thus the rainbow flag isn't rendered.
The Twemoji loader already has an exception for flags - it'll load if the browser supports everything but flags, and then only replace flag emoji, leaving everything else as native rendering. To provide a seamless experience for all flags the loader now uses the rainbow flag to test flag support.
Props pento.

This includes a new test in the emoji loader, to see if the browser supports rendering Unicode 9.0 emoji, as well as an update to `twemoji.js`, to load Unicode 9.0 twemoji images.
The default CDN location for loading Twemoji images has changed, moving to a versioned subdirectory. This allows updates without needing to purge the CDN.

Let's make sure this won't happen by validating the permalink structure.

When the browser test for diversity emoji was added in [36160], it included a workaround for Chrome not being able to compare `Uint8ClampedArray` objects directly, by converting them to a string. Unfortunately, Safari doesn't support the `Uint8ClampedArray.toString()` method correctly, so the test was incorrectly failing in Safari.

Previously, `&` would be converted everywhere, which caused problems when it was converted within a `<script>`, for example.
`convert_chars()` is now removed from the `the_content` filter, as it was doing the same job as `wptexturize()`.
KSES correctly handles converting `&` within HTML attributes, so there's no need for `wptexturize()` and `convert_chars()` to do the same job.
