[PATCH 18/23] readdir_r.3: SYNOPSIS: Use 'restrict' in prototypes

[Alejandro Colomar <alx.manpages@gmail.com>]

Both POSIX and glibc use 'restrict' in readdir_r().
Let's use it here too.

.../glibc$ grep_glibc_prototype readdir_r
dirent/dirent.h:183:
extern int readdir_r (DIR *__restrict __dirp,
		      struct dirent *__restrict __entry,
		      struct dirent **__restrict __result)
     __nonnull ((1, 2, 3)) __attribute_deprecated__;
.../glibc$
