immediately converted back to "pointer to function" again. Note: Because of
performance considerations, cc65 does treat functions as "pointer to function"
internally, but nevertheless dereferencing a function must be possible.

When assigning structures, copy them using the primary register when the
size is 1, 2, or 4.
When assigning structures, allow structures by value when the size is 1,
2, or 4. These structures are expected to be in the primary register. The
only case when this can happen is by return from function, so this change
makes div() work.

Fixed a problem with K&R functions: In a function with no return type
specified, the compiler did not allow a simple "return" statement. However,
there was no "void" type at that time, so it was not possible to specify
something else. The solution is to allow omission of a return value in a
K&R function with an implicit int type. Other types or an explicit int is
still checked.

* __fixargs__ is now an actual function symbol and no longer handled in the
scanner.
* Additional symbol __argsize__ that is a constant in normal functions and
a const local variable for variadic functions. Using this symbol, the
va_arg macro gets a lot simpler and smaller.
* Added special code to handle the fixed parameters of a variadic function.
The code has some overhead, but the va_fix macro is no longer needed (and
the compiler generated code is better than va_fix anyway).

A cast with a function on the right side resulted in an internal compiler
