Extensively changed the DEF file generator mkdef.pl to use a modified version
of Ulf's prototype parser, also general tidying and fixing of several problems
with the original. Its still a bit of a hack but should work.

This is the last bit of the old code that uses the K&R prototypes: after some
testing they can finally go away...
