Update Parameters $protocols for /esc_url/ page

[emiluzelac]

We're missing few protocols in: ​https://core.trac.wordpress.org/browser/tags/4.2.2/src/wp-includes/formatting.php#L3096

'http', 'https', 'ftp', 'ftps', 'mailto', 'news', 'irc', 'gopher', 'nntp', 'feed', 'telnet', 'mms', 'rtsp', 'svn', 'tel', 'fax', 'xmpp'

This reflects: ​https://developer.wordpress.org/reference/functions/esc_url/

Hi Emil, thanks for the ticket.

This should really be a core trac ticket. That said, I think the best approach would be to document the default list in the DocBlock for wp_allowed_protocols() and then cross-reference that everywhere. Otherwise, we end up having to keep the list updated in multiple places, which can fall out of date.

Created ​#wp32421.
