59e96ef740 Turned the 'ST' status byte into a symbol resolved by the linker in order to allow to use it from code living in the 'cbm' directory.
Moved getdevice.s from 'c64'/'c128' to 'cbm' making use of the new 'ST' setup.

8aff2a9159 Fixed a problem with the last change in crt0.s: The symbols for the RAM memory
area had been used but not defined in the linker config. Changed the startup
module and the linker config to use the common loadaddr and exehdr modules.

eef8ecc74d User linker generated symbols for stack placement (like most other targets) instead of a hardcoded constant in order to allow control of stack placement via linker configuration.

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.

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.

d28ba06f79 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.

See also R3897 where this change was done for other platforms.

e5cbba264f Move the irqcount variable from BSS into DATA, since it is used by the
interrupt handler, which is installed *before* zerobss is called.

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.
