Connect User Data Option

This rarely used option that may be needed for comm tools that wish to build upon the base IrDA comm tool. This is the *kCMOIrDAConnectUserData option, which is used during connect time to send/receive "out of band" data. See the IrDA documentation to get an idea of how this would be used (specifically IrTinyTP and IrComm).

 local option := {

   label: kCMOIrDAConnectUserData, // IrDA connect user data
   type:   'option,
   opCode: opSetRequired,
   data: {
      arglist: [
         3, // length of data; strlen("foo")
         "foo", // data string
      ],
      typelist: [
         'struct,
         'uLong, // fDataLength; default is 0
         ['array, 'char, 0], // fData
      ], 
   },
 };

The fields fDataLength and fData are used together to describe data to be sent/received during connect/listen.
