Now, the Linker::LinkModules() call doesn't link in any functions marked as 'internal', which is problematic, since we'd like to have just about all of the builtins marked as internal so that they are eliminated after they've been inlined when they are in fact used. This change removes all of the internal qualifiers in the builtins and adds a lSetInternalFunctions() routine to builtins.cpp that sets this property on the functions that need it after they've been linked in by LinkModules().
