libphonenumber supports these since December 2015 / January 2016. Most of these changes went into libphonenumber-7.2.2 (Dec 15, 2015), the last changes related to this into libphonenumber-7.2.4 (Jan 28, 2016). This was about adding EU-wide helplines 116xxx (http://ec.europa.eu/digital-agenda/en/116-helplines). See: https://github.com/googlei18n/libphonenumber/blob/master/java/release_notes.txt Closes #6130
