    ipfilter: Add DTrace SDT probe
    
    Add an SDT probe, using the newly created DT5 macro, in similar vein
    to DEBUG_PARSE printf for when FTP junk is anticipated and ok. This
    will assist in debugging port (active) FTP proxy issues.
    
    (cherry picked from commit 106f42596e4b61c26425735a3999bd51d39dd82c)
