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.
Props jmdodd for feedback, suggestions, and insults where appropriate.

Previously, these filters were being run once per post, but the changes in [41043] caused them to be run once per emoji found.
We will not stand idly by while this kind of unfair performance penalty is placed on the emoji literate. The filters are now run once only, emoji aficionados everywhere can rest easy, knowing their posts will be just as performant as their emoji-less cousins.
Props ocean90 for noticing this severe oversight.

Previously, `wp_encode_emoji()` and `wp_staticize_emoji()` used inaccurate regular expressions to find emoji, and transform then into HTML entities or `<img>`s, respectively. This would result in emoji not being correctly transformed, or occasionally, non-emoji being incorrectly transformed.
This commit adds a new `grunt` task - `grunt precommit:emoji`. It finds the regex in `twemoji.js`, transforms it into a PHP-friendly version, and adds it to `formatting.php`. This task is also automatically run by `grunt precommit`, when it detects that `twemoji.js` has changed.
The new regex requires features introduced in PCRE 8.32, which was introduced in PHP 5.4.14, though it was also backported to later releases of the PHP 5.3 series. For versions of PHP that don't support this, it will fall back to an updated version of the loose-matching regex.
For short posts, the performance difference between the old and new regex is negligible. As the posts get longer, however, the new method is exponentially faster.

Previously, the UN flag test relied on the image being produced to be quite small. Unfortunately, the Chrome PNG encoder seems to have changed recently, and it now produces a relatively large image.
For a better test, we can compare the rendering of [U] + [N] against [U] + zero width space + [N].

Like its predecessor (`sanitize_text_field()`), `sanitize_textarea_field()` is a helper function to sanitise user input. As the name suggests, this function is for sanitising input from `textarea` fields - it strips tags and invalid UTF-8 characters, like `sanitize_text_field()`, but retains newlines and extra inline whitespace.

[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.
