Add sysmon support for indicator pins (mostly taken from pcf8574).

The Sun V245 uses a PCA9555 for the disk present indications.

Set the "active high" flag on the correct pin.

Make prev_state the correct size (only used when debug defined).

Split out the logic for handling indicators, alerts and timeouts, rather
than having special values in the properties.

Set envsys critical state for alerts when the sensor value isn't the default.

Add comments to explain the logic.
