* All platforms:
o mgmt console: as currently passes straight in_addr_t bits around
o make possible to get AF from getaddrinfo() answer, ie allow openvpn to
use ipv4/6 if DNS returns A/AAAA without specifying protocol.
Hard: requires deep changes in initialization/calling logic
o use AI_PASSIVE
o the getaddr()/getaddr6() interface is not prepared for handling socktype
"tagging", currently I abuse the sockflags bits for getting the ai_socktype
downstream.
o implement comparison for mapped addesses: server in dual stack
listening IPv6 must permit incoming streams from allowed IPv4 peer,
currently you need to pass eg: --remote ffff::1.2.3.4
o do something with multi mode learn routes, for now just ignoring
ipv6 addresses seems the most sensible thing to do, because there's
no support for intra-tunnel ipv6 stuff.
* win32:
o find out about mapped addresses, as I can't make it work
with bound at ::1 and connect to 127.0.0.1
* N/A:
o this is ipv6 *endpoint* support, so don't expect "ifconfig6"-like
support in this patch
