 PR/48475: YAMAGUCHI Takanori: EDNS option broken with unbound. struct
 querybuf in net/gethnamaddr.c defines MAXPACKET to 64K. This in turn
 gets passed down until it reached res_nopt(..., answer, anslen), where
 the size of the buffer must fit in 16 bits. Unfortunately we end up
 being one more than the max so we end up sending a 0 as the size and
 unbound does not like that. Instead we clip now to 64K - 1, and
 everyone is happy.
