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.

Rewrite of CharMapPragma in pragma.c
Fixed bug in scanner.c: Invalid octal constants containing the numbers 8
and 9 were accepted by the compiler.
Moved SignExtendChar from scanner.c to datatype.c.

internal compiler errors in several places.
An old cc65 extension (variables of type void) was broken and did no longer
work. Fixed that.

unused stores into these registers.
Because of this, the old code using regsave does no longer work. Started
to rewrite it.

* __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).

optimization for C functions. The last parameter is not pushed onto the
stack by the caller but in the function entry code, so there is no speed
but a size gain.

Check for and honour const in several places: Assignment to const is flagged
with an error. Const data is placed in the rodata segment.
