* cygtls.h (_local_storage::setmode_file): New element. 

(_local_storage::setmode_mode): New element.
* tlsoffsets.h: Regenerate.
* cygwin.din (setmode): Define as cygwin_getmode.
* syscalls.cc (setmode_helper): Use setmode_* variables from tls rather than
using unthreadsafe static.
(setmode): Break out fwalk stuff.
(cygwin_setmode): New function.  Put fwalk stdio stuff here.
