QSslCertificateExtension only returns 1 out of multiple DNS names in 2.5.29.17 ("Subject Alternative Name")

QTBUG-86830 patched QSslCertificateExtension to return a QMap. However, 2.5.29.17 might store multiple DNS names (see http://www.jasinskionline.com/technicalwiki/(S(bzkezjfs0nags1zp1qq0abb4))/Print.aspx?Page=Requesting-an-SSL-Certificate-for-Multiple-Domains for example) – storing the data in a QMap results in only 1 value being retained in the "DNS" key.

Suggestion

Use a QMultiMap::insertMulti() instead of a QMap::insert()
