[Ada] GNAT.Sockets: support ICMP, IGMP and RAW IP protocol levels

2019-07-11  Dmitriy Anisimkov  <anisimko@adacore.com>

gcc/ada/

	* libgnat/g-socket.ads (Level_Type): Add enumerators for
	IP_Protocol_For_ICMP, IP_Protocol_For_IGMP,
	IP_Protocol_For_RAW_Level.
	* libgnat/g-socket.adb (Levels): Handle them.
	* s-oscons-tmplt.c: Import socket protocols defined in
	netinet/in.h.
