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)
