	* socket.c, g-socthi-vms.adb, g-socthi-vms.ads, g-socthi-vxworks.ads,
	s-oscons-tmplt.c, gsocket.h, g-socthi-mingw.ads, g-socthi.ads,
	g-sothco.ads (__gnat_inet_pton): Needs to be enabled for HP-UX as well,
	since HP-UX supports neither inet_aton nor inet_pton (altough the
	latter is part of the Single UNIX Specification!).
	So reorganize code, and share C implementation based on inet_addr(3)
	with VMS (instead of having a VMS specific Ada implementation in
	g-socthi-vms.adb).
