glibc uses 'restrict' in random_r(), initstate_r(), setstate_r().
Let's use it here too.

.../glibc$ grep_glibc_prototype random_r
stdlib/stdlib.h:434:
extern int random_r (struct random_data *__restrict __buf,
		     int32_t *__restrict __result) __THROW __nonnull ((1, 2));
.../glibc$ grep_glibc_prototype initstate_r
stdlib/stdlib.h:440:
extern int initstate_r (unsigned int __seed, char *__restrict __statebuf,
			size_t __statelen,
			struct random_data *__restrict __buf)
     __THROW __nonnull ((2, 4));
.../glibc$ grep_glibc_prototype setstate_r
stdlib/stdlib.h:445:
extern int setstate_r (char *__restrict __statebuf,
		       struct random_data *__restrict __buf)
     __THROW __nonnull ((1, 2));
.../glibc$
