Message:

General: Add support for unicode email addresses in is_email and sanitize_email

This adds support for the unicode address extensions in RFC 6530-3 and refactors the code so there are fewer long regexes and less duplication between sanitize_email and is_email. A new class, WP_Email_Address, provides the shared parts.

Opting out of unicode support is easy, default-filters.php adds unicode support by adding filters, which can be removed.

sanitize_email no longer does major changes like removing an entire subdomain from someone's address, it only cleans up things like soft hyphens and whitespace — changes that happen when coping an email address from text.
