Switched Apple II output format to AppleSingle. Although the primary target OS for the Apple II for sure isn't DOS 3.3 but ProDOS 8 the Apple II binary files contained a DOS 3.3 4-byte header. Recently I was made aware of the AppleSingle file format. That format is a much better way to transport Apple II meta data from the cc65 toolchain to the ProDOS 8 file system. Therefore I asked AppleCommander to support the AppleSingle file format. Now that there's an AppleCommander BETA with AppleSingle support it's the right time for this change. I bumped version to 2.17 because of this from the perspective of Apple II users of course incompatible change.

Moved run location of ONCE segment. Make the same changes to the Apple II that were done with https://github.com/cc65/cc65/commit/0ee9b2e446198746c3a05b142ecd00784becf727 to the C64. Notes: - The startup code deliberately doesn't make use of symbols defined for the LC segment as that segment is optional. - The <...>-asm.cfg configs move the segment BSS to an own memory area BSS although this doesn't seem necessary. However the benefit is that the size of the memeory area MAIN is identical to the number of bytes loaded from disk into RAM. To keep this an invariant for all Apple II configs allows to simplify the EXEHDR to just refer to the symbols defined for MAIN.

__STACKSIZE__: type = weak, value = $0800; # 2k stack
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. git-svn-id: svn://svn.cc65.org/cc65/trunk@5722 b7a2c559-68d2-44c3-8de9-860c34a00d81

Renamed INITBSS to INIT and INIT to ONCE. The way we want to use the INITBSS segment - and especially the fact that it won't have the type bss on all ROM based targets - means that the name INITBSS is misleading. After all INIT is the best name from my perspective as it serves several purposes and therefore needs a rather generic name. Unfortunately this means that the current INIT segment needs to be renamed too. Looking for a short (ideally 4 letter) name I came up with ONCE as it contains all code (and data) accessed only once during initialization.
