vastly improved awk based code generator now handles recursive function definitions, unions etc it is sufficient for some basic types like UNISTR2 and BUFFER5 to be defined in the *.struct file and used successfully this generator uses templates (in *.tpl files) for all code generation, allowing easy replacement of the backend functions (This used to be commit 14ded82dc92ae6eff7639351f391a33b9cc31c0d)
