Mark internal dirent functions with attribute_hidden [BZ #18822]
Mark internal dirent functions with attribute_hidden to allow direct
access within libc.so and libc.a without using GOT nor PLT. __readdir64
is hidden with libc_hidden_proto and libc_hidden_def since the exported
readdir64 is an alias of __readdir64.
[BZ #18822]
* include/dirent.h (__opendir): Always add attribute_hidden.
(__fdopendir): Likewise.
(__closedir): Likewise.
(__readdir): Likewise.
(__readdir64): Add libc_hidden_proto.
* sysdeps/mach/hurd/readdir64.c (__readdir64): Add libc_hidden_def.
* sysdeps/unix/sysv/linux/i386/readdir64.c (__readdir64): Likewise.
* sysdeps/unix/sysv/linux/readdir64.c (__readdir64): Likewise.
* sysdeps/unix/sysv/linux/wordsize-64/readdir.c (__GI___readdir64):
New alias.
