mail-mta/netqmail: Add SMTPUTF8 support for qmail

SMTPUTF8 (RFCs 6531 and 6532, plus several that aren't relevant to qmail) allows using unencoded UTF8 almost everywhere in email, including in localparts, domains, subjects and message bodies. Thanks to cnnic.cn for sponsoring this work. (cherry picked from commit 5116b83a9bf93f59fb7b7d3fcd286f7b2c4da438) Signed-off-by: Robin H. Johnson <robbat2@gentoo.org>
