* configure.ac: Added test for broken CMSG_FIRSTHDR macro
(relevant for Solaris 8 and unpatched Solaris 9, don't know
whether other platforms are affected).
* zebra.h: Define ZCMSG_FIRSTHDR appropriately based on whether
config.h indicates HAVE_BROKEN_CMSG_FIRSTHDR (as determined
by the configure test program).
* sockopt.c: (getsockopt_cmsg_data) Use ZCMSG_FIRSTHDR instead
of CMSG_FIRSTHDR.
* rtadv.c: (rtadv_recv_packet,rtadv_send_packet) Use ZCMSG_FIRSTHDR
instead of CMSG_FIRSTHDR.
* ripd.c: (rip_recvmsg) Use ZCMSG_FIRSTHDR instead of CMSG_FIRSTHDR.
* ripngd.c: (ripng_recv_packet) Use ZCMSG_FIRSTHDR instead of
CMSG_FIRSTHDR.
