    13.2 relnotes: update hostid/machine-id items
    
    The details of the addition of /etc/machine-id have changed, along
    with the type of /etc/hostid if it is generated.  Update the release
    notes accordingly.  Also document uuidgen -r, used by the hostid
    script.  Also include a change from my previous review that I
    missed.

+The `hostid` startup script will now generate a random (version 4) UUID if there is no [.filename]#/etc/hostid# file and no valid UUID from hardware.
+Also, if there is no [.filename]#/etc/machine-id# file, the `hostid_save` script will store a compact version of the hostid (one without hyphens) in [.filename]#/etc/machine-id#.
