gethostbyname.3: SYNOPSIS: Use 'restrict' in prototypes 

glibc uses 'restrict' in gethostent_r(), gethostbyaddr_r(),
gethostbyname_r(), gethostbyname2_r().
Let's use it here too.

.../glibc$ grep_glibc_prototype gethostent_r
resolv/netdb.h:165:
extern int gethostent_r (struct hostent *__restrict __result_buf,
			 char *__restrict __buf, size_t __buflen,
			 struct hostent **__restrict __result,
			 int *__restrict __h_errnop);
.../glibc$ grep_glibc_prototype gethostbyaddr_r
resolv/netdb.h:170:
extern int gethostbyaddr_r (const void *__restrict __addr, __socklen_t __len,
			    int __type,

			    char *__restrict __buf, size_t __buflen,
			    struct hostent **__restrict __result,
