properly store IPv6 addresses in struct tun_t
All addresses in struct tun_t were stored as an in_addr.
But IPv6 addresses need an in6_addr, so switch tun_t addresses
to the in64_addr wrapper struct.
This is an ABI break, as documented in TODO-RELEASE.
Fixes an out of bounds memcpy() identified by Coverity.
