fix handling of IPv6 UDP connections
...
Problem:
IPv6 addresses are 4 bytes long and don't fit inside a `sockaddr`, so
`recvfrom` will truncate the address to the first half.
When generating a reply, the remaining half of the address is filled
with garbage and the packet is subsequently delivered to the wrong host,
if not immediately dropped.
Solution:
replace `sockaddr` with `sockaddr_storage`, the latter is guaranteed to
be large enough to hold an IPv6 address and pointers can be cast to
`sockaddr *` when needed.
