diexec: Interrupt API changes (nw)
- PULSE_LINE is no longer a value. Existing uses have been changed to pulse_input_line with attotime::zero as the second argument. - Formerly only INPUT_LINE_NMI and INPUT_LINE_RESET were allowed with PULSE_LINE. INPUT_LINE_NMI no longer receives special handling; instead, CPU devices must specify which of their input lines are edge-triggered and thus may be used with zero-width pulses by overriding the execute_input_edge_triggered predicate. INPUT_LINE_RESET is still special-cased, however. - execute_default_irq_vector now allows a different default vector to be specified for each input line. This added flexibility may or may not prove useful.
