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.

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

supplied data structures. Re-added the -T option which is much more exact
now because of the better line info stuff.
Cleanups in the scanner (remove old #defines).

* __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).

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

Rewrote the include file management, keeping a list of all include files
and cleaning up the code while going.

Several renames for better readibility.
Removed separate struct and enum symbol tables in favour of one tag table.
Check for some more error conditions or dubious constructs.
