IPTOS constants

[Dag-Erling Smørgrav]

defines.h defines a bunch of IPTOS constants if they're not already
available:

#ifndef IPTOS_LOWDELAY
# define IPTOS_LOWDELAY          0x10
# define IPTOS_THROUGHPUT        0x08
# define IPTOS_RELIABILITY       0x04
# define IPTOS_LOWCOST           0x02
# define IPTOS_MINCOST           IPTOS_LOWCOST
#endif /* IPTOS_LOWDELAY */

A few lines further down, it includes <netinet/ip.h>, which is where
those constants are defined (at least in FreeBSD).

These include directives should really be moved to includes.h - in fact,
<netinet/in_systm.h> is already there.
