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

glibc uses 'restrict' in getnetent_r(), getnetbyname_r(),
getnetbyaddr_r().
Let's use it here too.

.../glibc$ grep_glibc_prototype getnetent_r
resolv/netdb.h:235:
extern int getnetent_r (struct netent *__restrict __result_buf,
			char *__restrict __buf, size_t __buflen,
			struct netent **__restrict __result,
			int *__restrict __h_errnop);
.../glibc$ grep_glibc_prototype getnetbyname_r
resolv/netdb.h:246:
extern int getnetbyname_r (const char *__restrict __name,
			   struct netent *__restrict __result_buf,
			   char *__restrict __buf, size_t __buflen,
			   struct netent **__restrict __result,
			   int *__restrict __h_errnop);
.../glibc$ grep_glibc_prototype getnetbyaddr_r
resolv/netdb.h:240:
extern int getnetbyaddr_r (uint32_t __net, int __type,
			   struct netent *__restrict __result_buf,
			   char *__restrict __buf, size_t __buflen,
			   struct netent **__restrict __result,
			   int *__restrict __h_errnop);
