da766d872c Small code changes for more safety (and to be compatible with the new shift 
routines that don't use the stack).

1. Its use isn't limited to code. It may as well be used for rodata.
2. This fits better to the new __LCADDR__ / __LCSIZE__ parameters.

c9555b328a The Apple2 linker configs basically cover two dimension of settings: 
1. BIN vs. SYS vs. Loader
2. With Quit code vs. w/o Quit code vs. full LC

Up two now these two dimensions were sort of folded into a number of useful combinations. However with the new asm config and the upcominger overlay config we end up with just to many configs.

Therefore now the second dimension isn't expressed anymore as distinct config. Rather the user has to override __LCADDR__ and __LCSIZE__ in order use the Quite code area or the full LC.
