81cfbe06c6 Changed the startup module and the linker config for the Commodore VIC to use
the common loadaddr and exehdr modules.

d1f5b74f01 Now that we reduce the size of the RAM memory area by the stacksize in the linker configuration we need to add the stacksize to end of the RAM area when setting the initial stack pointer in the startup code.

60bc009991 * Moved the BASIC stub that calls the compiled program into it's own segment
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.

c7a33334ba Don't hardcode the address of the SYS call for the startup code of the
Commodore machines.

8216bf1d6a Force an import of the special symbol __STARTUP__ in the C compiler when
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.

7e9b6e7311 Fixed problems with the startup code (Greg King): Interrupts must be hooked
before calling initlib because initlib calls contructors and may install
drivers, which enable hardware interrupts. Similar for donelib.

7a5d4f3138 Fixed issues with the last change: The return code must be pulled from stack
before the stack pointer is reset.

be5adac693 Use the assembler version as BASIC line number, so the version of the
assembler (and probably compiler) can be determined from a compiled
executable. Nice idea from Stefan Haubenthal.

3b3e1bec17 Removed the empty LOWCODE segments from the startup files. This is now
handled by the OPTIONAL segment attribute in the linker config.

6d498d8187 Use external symbols for the CBM kernal jump table functions. This allows
to emulate these functions on platforms where one or more of these functions
are not available (PET, CBM-II).
