kernal routine does not work, when the cursor is not at the same position
where it was switched on, because when switching it on, the kernal remembers
the character attribute and restores this when switching it off. So characters
may get the wrong attribute. The solution is to always switch the cursor on,
before switching it off.

cleared, which in turn causes the display to scroll when a character is output
in the lower right corner.

Machines with RAM in pages 2+3 are quite rare, so it's better to have the
additional code+features in a separate driver.

Note: Originally I planned to create a module to be linked to the driver. However this turned out to cause quite some issues with the Makefiles - especially on the Apple2 where one driver uses to generic LINE implementation and the other doesn't. The final Makefile was so ugly that I rather opted for including the code in question on source level. In order to avoid to unwanted cross dependencies the whole .inc file content is wrapped in its own scope.

named EXEHDR.
* Renamed BASICHDR to EXEHDR for the PET-II machines.
* Moved the call to CHRCH in front of the code that saves the zero page, since
open files are sometimes remembered in the zero page, so we need to close
them before we grab a copy.

* Removed CIRCLE
* Aspect ratio is a new header variable
* Removed the reserved bytes - it's easier to bump the API version
* Clipping is done completely in the wrapper

Added --forget-inc-paths to the command line of the assembler in the
Makefiles, because the assembler does now have builtin paths and will find
include files from an installation first.
Hopefully fixed any problems that arose from the two changes.

assembler. The assembler will otherwise emit a warning when just translating
the module.

main() is encountered. Define this symbol in the startup code. This will
automatically force linking of the startup code which can then reside inside
the standard library as any other object file.

routine reads the TOD clock of CIA1 on the C64 and C128. Since systime was a
dummy routine common for all CBMs before, this change adds an individual dummy
routine for all other CBM systems. CBM510/610 do also have a TOD clock, so a
similar function as in the C64 could be used ...

drivers, which enable hardware interrupts. Similar for donelib.

must now return carry set if the interrupt has been handled, and carry clear
if not. The callirq routine will stop calling handlers with the first handler
that claims to have handled the interrupt. callirq will return the carry flag
to the caller as it came from the last interruptor called.
