Console: integrate end-of-line hack with cursor positioning.
The previous work for simulating the beyond-right-edge of screen cursor position is incomplete without integrating this into the cursor positioning routines. By making the cursor routines aware of the eat_newline flag, we allow cursor movements to work correctly with regard to this simulated position. * winsup/cygwin/fhandler_console.cc (fhandler_console::cursor_set): If the X position is beyond the right edge of the screen, then set the cursor to the start of the following line, rather than clipping to the right edge, set the eat_newline flag, indicating that the the true position is actually one character beyond the previous line. In all other cases, clear the eat_newline flag. (fhandler_console::cursor_rel): Do not apply the delta vector to the raw Win32 cursor position; call cursor_get and apply it to the virtual cursor position which takes into account the eat_newline flag. (fhandler_console::cursor_get): Take into account the eat_newline flag. If it is set, then report an adjusted position that is one column beyond the end of the previous line.
