Fixes for typedef serialization of functions..

Also fix for HashTable<>::rehash_fast not having finished implemenation...

The typedef fix is a sort of hack (like how parsing the rest of the language feels like tbh...).
I might make a def_typedef_fn to make it clearer how to define function typedefs using the upfront interface.
