   If drivemode is true, tftp server will use connection threads and will
   comply to all naviserver driver rules. Otherwise it will create thread 
   for each request without any restrictions.

   proc is Tcl proc whic is called just before requested file will be opened and
   it can return new file name instead of original.
   
   Format is:
   proc tftpproc { file ipaddr } {
   }
