Emit the Event.StateSensorEvent signal
When the PLDM daemon receives a state sensor EventMessages, it emits the
StateSensorEvent signal (with TID, sensorID, sensorOffset, eventState,
previousEventState as the signal data).
This commit implements a DBus interface defined at
https://gerrit.openbmc-project.xyz/c/openbmc/phosphor-dbus-interfaces/+/33552
to provide StateSensorEvent signal.
Tested: Tested ok in fp5280g2 system.
1、Using pldmtool to send a sensor event message:
pldmtool raw -d 0x80 0x02 0x0A 0x01 0x01 0x00 0x2 0x00 0x01 0x03 0x04 0x05
2、Using dbus-monitor tool we can see the signal being emitted:
signal time=6467.863313 sender=:1.107 -> destination=(null destination)
serial=37 path=/xyz/openbmc_project/pldm;
interface=xyz.openbmc_project.PLDM.Event; member=StateSensorEvent
