Get rid of several unused variables

* cmd_definekey: actually use cmd
* cmd_meta: remove ev1
* cmd_resize: remove nbytes
* cmd_ratrelwarp: remove s
* draw_string: remove lgv, lgc, mask; lgc wasn't XFreeGC'ed
* get_more_input: remove nbytes
* cleanup_frame: remove last_win
* get_window_list: remove other_window
