* win32/win32.c (_filbuf): msvc14 doesn't have it, use _fgetc_nolock.

* win32/win32.c (_flsbuf): msvc14 doesn't have it, use _fputc_nolock.

* win32/win32.c (vcruntime_file): define vcruntime_file on msvc14
  because it doesn't export FILE's internal structure.

* win32/win32.c (FILE_COUNT): added to abstract FILE->_cnt.

* win32/win32.c (FILE_READPTR): added to abstract FILE->_ptr.

* win32/win32.c (FILE_FILENO): added to abstract FILE->_file.

* win32/win32.c (init_stdhandle): use FILE_FILENO.

* win32/win32.c (rb_w32_getc): use FILE_COUNT and FILE_READPTR.

* win32/win32.c (rb_w32_putc): ditto.
