  Log:
  Create a more modular type system for the FT_* types. Put them
  into epan/ftypes.
  
  Re-write display filter routines using Lemon parser instead of yacc.
  Besides using a different tool, the new grammar is much simpler, while
  the display filter engine itself is more powerful and more easily extended.
  
  Add dftest executable, to test display filter "bytecode" generation.
  Add option to "configure" to build dftest or randpkt, both of which are not
  built by default.
  
  Implement Ed Warnicke's ideas about dranges in the new display filter and
  ftype code.
  
  Remove type FT_TEXT_ONLY in favor of FT_NONE, and have protocols registered
  as FT_PROTOCOL. Thus, FT_NONE is used only for simple labels in the proto tree,
  while FT_PROTOCOL is used for protocols. This was necessary for being
  able to make byte slices (ranges) out of protocols, like "frame[0:3]"
  
  Win32 Makefile.nmake's will be added tonight.
