Add SEL Logger Daemon

This change adds a SEL Logger daemon that handles all requests
to add new IPMI SEL records to the journal with the correct
metadata.

The expected metadata for a SEL record are
    MESSAGE_ID = Used to identify SEL journal records, the SEL
                 MESSAGE_ID is b370836ccf2f4850ac5bee185b77893a
    IPMI_SEL_RECORD_ID = Two byte unique SEL Record ID
    IPMI_SEL_RECORD_TYPE = The type of SEL entry (system or OEM)
                           which determines the definition of the
                           remaining bytes
    IPMI_SEL_GENERATOR_ID = The IPMI Generator ID (usually the
                            IPMB Slave Address) of the requester
    IPMI_SEL_SENSOR_PATH = D-Bus path of the sensor in the event
    IPMI_SEL_EVENT_DIR = Direction of the event (assert or deassert)
    IPMI_SEL_DATA = Raw binary data included in the SEL record

It exposes an interface for manually adding System and OEM type SEL
events, and provides the capability to monitor for types of events
and log them automatically.

The interface for System type events requires a text message for the
journal entry, the sensor path, up to three bytes of SEL data, the
direction of the event, and the generator ID of the requester.

The interface for OEM type events requires a text message for the
journal entry, up to thirteen bytes of SEL data (depending on the
record type), and the record type.

The MESSAGE_ID and IPMI_SEL_RECORD_ID metadata are added by the
daemon.
