Fix tracing of rewinddir function

While trying to get the ATHTTPD server working, I found a bug in the file I/O
subsystem. I guess it only occures when tracing and assertions are turned on.

The Assertion I got, when accessing a webpage:

ASSERT FAIL: <6>cyg_trac.h[666]void Cyg_TraceFunction_Report_::set_exitvoid()
exitvoid used in typed function
ASSERT FAIL: <6>cyg_trac.h          [ 666] void
Cyg_TraceFunction_Report_::set_exitvoid()                                      
                exitvoid used in typed function


I hunted it down to the rewinddir() function. rewinddir returns void, which
fails because the macro FILEIO_ENTRY uses CYG_REPORT_FUNCTYPE( "returning %d"
), which sets a string for return.

rewinddir seems to be the only function returning void.
I fixed the problem by introducing a macro FILEIO_ENTRY_VOID which simply uses
CYG_REPORT_FUNCTION();

Find the patch attached and feel free to integrate it in CVS.
