* readline.c (rl_save_state, rl_restore_state): Support systems
that don't define SIGWINCH.
* terminal.c (_rl_get_screen_size) [__DJGPP__]: Compute the
screen width and height using console I/O.
(_rl_init_terminal_io) [__MSDOS__]: Zero out all the _rl_term_*
variables. Convert to _rl_* naming scheme.
(_rl_set_cursor) [__MSDOS__]: Ifdef away this function.
* display.c (_rl_move_vert) [__MSDOS__]: Don't use undeclared
variable `l'. Use `delta' instead recomputing its value anew.
Assign -delta to i instead of the other way around.
