	* add timed interrupt generator: cpunum_toggle_input_line_timed(cpu, input, time). This will ASSERT_LINE immediately and then CLEAR_LINE after the specified time. 'time' can be zero, which is equivalent to PULSE_LINE, though perhaps we should discourage such usage since it's not realistic. If you've asserted the line via this function, and another cpunum_assert_input_line_timed() call is made, it will override the previous CLEAR_LINE time with the new time. Note that this is not a proper wire-OR, so we could alternatively reschedule the CLEAR_LINE to the maximum of the new time and the previously pending time.		* add timed interrupt generator: cpunum_toggle_input_line_timed(cpu, input, time).
