commit c52c11299f343168a6335adf6de21c2c01945a50

    pervasive: use [!]address_is_specified() instead of address_is_any()
    
    Where address_is_specified() is defined as: !unset && !:: && !0.0.0.0
    
    Use the field <<enum keyword_host type>> to determine if the host
    address (set or not) is %any, a DNS address, from the wire, ...
    
    Use address_is_specified() to see if it's been set.
