pass valsize for getsockopt like we do for setsockopt
make sure that we have enough space, don't require the exact size
(Tom Ivar Helbekkmo)

1) "#define ipi_spec_dst ipi_addr" in <netinet/in.h>
2) Change the IP_RECVPKTINFO option to control the generation of
   IP_PKTINFO control messages, the way it's done in Solaris.
3) Remove the superfluous IP_RECVPKTINFO control message.
4) Change the IP_PKTINFO option to do different things depending on
   the parameter it's supplied with:
   - If it's sizeof(int), assume it's being used as in Linux:
     - If it's non-zero, turn on the IP_RECVPKTINFO option.
     - If it's zero, turn off the IP_RECVPKTINFO option.
   - If it's sizeof(struct in_pktinfo), assume it's being used as in
     Solaris, to set a default for the source interface and/or
     source address for outgoing packets on the socket.
5) Return what Linux or Solaris compatible code expects, depending
   on data size, and just added a fallback to a Linux (and current NetBSD)
   compatible value if the size is unknown (as it is now), or,
   in the future, if the calling application specifies a receiving
   buffer that doesn't match either data item.

new sentence-new line

Remove comment now that the getsockopt code passes the size.

Add a new sockopt member to keep track of the actual size of the option
that should be returned to the caller in getsockopt(2).
