Restored the old C-stack initiation code.

Reduced the size of the moveinit subroutine.
...
Made other changes that were recommended by Oliver.
* Changed its name from move_init to moveinit.
* Used self-modifying code in the subroutine.
* The INIT segment doesn't need to be optional (it's used by the start-up file).

Adapted, to the c64 target, the INIT-segment overlay scheme from the apple2 targets.
...
When a program starts running, INIT is moved from one place to another place. Then, INIT's code is executed; and, the first place is re-used for variables. After the INIT code has finished, the second place can be re-used by the heap and the C stack. That means that initiation code and data won't waste any RAM space after they stop being needed.

Made the Commodore version of exec() work in programs that are so big that they load into all of BASIC RAM.

The function won't cause an "out of memory" error.

Moved two errno helper functions into separate files.
...
Only the function that actually is needed will be linked. It is very useful for targets that do not have file-system I/O.

Added empty IRQ backend.
...
The driver kernels all require IRQ handling even if the actual drivers don't make use of it. So in order to successfully link a NES program using the joystick and/or TGI driver there has to be at least a "dummy" IRQ backend.

Fix two string output functions' handling of their buffer-size parameter.
...
That parameter's type is unsigned; but, the functions return an int. If the size is too big for a signed integer, then return an error code.
If the size is zero, then don't write anything into a buffer (the buffer pointer may be NULL). But, do format and count the arguments.
