94ba9575ec Implement exec() for Atari XDOS. 
- Adds new ENOEXEC error code, also used by Apple2 targets.
- Maximum command line length is 40, incl. program name. This is
  an XDOS restriction.
- testcode/lib/tinyshell.c has been extended to be able to run
  programs.

d8c31cf1d3 Renamed RAM to MAIN for all disk based targets. 
The name RAM doesn't make much sense in general for a memeory area because i.e. the zero page is for sure RAM but is not part of the memory area named RAM.

For disk based targets it makes sense to put the disk file more into focus and here MAIN means the main part of the file - in contrast to some header.

Only for ROM based targets the name RAM is kept as it makes sense to focus on the difference between RAM and ROM.

7ebaec1802 Don't save and restore the zero page locations used. 
Saves 19 bytes code (in the exe file) and reduces memory footprint
of the program by 45 bytes (code & bss).

7c9171ee87 Moved IRQ hooking / unhooking from startup code to constructor / destructor to avoid linking in the hooking / unhooking code (and callirq) for the majority of cc65 prorams not linking in interruptors.

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.
