b7b7de55d0 Replaced "throwing away" of memeory area HEADER with the much more elegant "not referring" of symbol __EXEHDR__. This was recently made possible for the asm program config.

094ffa1984 Renamed segment 'HIGHCODE' to 'LC because: 
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.

ffc06fcea3 Apple GEOS reserves beside the main app area at $4000-$C000 a secondary app area at $0C00-$2000. While it was an elegant idea to use that secondary area for overlays at the end of the day those 5 kB are just too small. So now overlays go at the end of the main area (as with GEOS 64/128). 
However the stack (usually 1 kB) can be securely placed in the secondary area without effort from the side of the developer. The rest of the secondary area (usually 4 kB) is made available to the developer as (uninitialized) 'EXTBSS'.
