Fix __getcwd rewinddir namespace (bug 17584).
__getcwd is called from dcigettext.o (brought in by various ISO C
functionality), but calls rewinddir, which is not an ISO C function.
This patch makes __getcwd call __rewinddir instead and makes rewinddir
a weak alias for __rewinddir.
Since getcwd.c is shared with gnulib (albeit not merged in either
direction for a long time, and omitted from gnulib's
config/srclist.txt list of shared files) I put in a #ifndef _LIBC
define of __rewinddir to rewinddir, although a future merged version
of getcwd could end up looking significantly different.
Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by this patch).
[BZ #17584]
* dirent/rewinddir.c (rewinddir): Rename to __rewinddir and define
as weak alias of __rewinddir. Don't use libc_hidden_def.
(__rewinddir): Use libc_hidden_def.
* sysdeps/mach/hurd/rewinddir.c: Rename to __rewinddir and define
as weak alias of __rewinddir. Don't use libc_hidden_def.
(__rewinddir): Use libc_hidden_def.
* sysdeps/posix/rewinddir.c: Rename to __rewinddir and define as
weak alias of __rewinddir. Don't use libc_hidden_def.
(__rewinddir): Use libc_hidden_def.
* include/dirent.h (rewinddir): Don't use libc_hidden_proto.
(__rewinddir): Use libc_hidden_proto.
* sysdeps/posix/getcwd.c [!_LIBC] (__rewinddir): Define to
rewinddir.
(__getcwd): Use __rewinddir instead of rewinddir.
