use the SAN type tag in Mbed TLS verify_hostname and get_cert_sans (#2614)

* use the SAN type tag in Mbed TLS verify_hostname and get_cert_sans

Mbed TLS keeps a subjectAltName entry's GeneralName tag in buf.tag and the bare value in buf.p / buf.len. verify_hostname ignored the tag, so a dNSName whose bytes equal an address authenticated that IP host, and an iPAddress or rfc822Name was matched as a DNS pattern. get_cert_sans looked for the tag inside the value, so it reported no entries for an ordinary certificate, or part of a dNSName as an entry of its own.

* Shorten the SAN type comments
