Fix issue 4425 and issue 3014 on Windows. Treat ERROR_NO_DATA Windows 
error code as EPIPE error.

* subversion/include/svn_types.h
  (SVN__APR_STATUS_IS_EPIPE): New macro, same as APR_STATUS_IS_EPIPE with 
   additional handling of ERROR_NO_DATA on Windows.
* subversion/libsvn_subr/cmdline.c
* subversion/libsvn_subr/io.c
  (svn_cmdline_fputs, svn_cmdline_fflush, do_io_file_wrapper_cleanup): Use
   SVN__APR_STATUS_IS_EPIPE macro instead of APR_STATUS_IS_EPIPE.
