First steps towards supporting Apple GEOS. - The generated file is a "Apple GEOS Convert" format. - VLIR support is yet to come. - The "Apple GEOS UnConvert" tool is yet to come. git-svn-id: svn://svn.cc65.org/cc65/trunk@5336 b7a2c559-68d2-44c3-8de9-860c34a00d81

Introduced __BACKBUFSIZE__ which can be set to zero in order to disable the GEOS background buffering. git-svn-id: svn://svn.cc65.org/cc65/trunk@5370 b7a2c559-68d2-44c3-8de9-860c34a00d81

__BACKBUFSIZE__: type = weak, value = $2000;
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'. git-svn-id: svn://svn.cc65.org/cc65/trunk@5696 b7a2c559-68d2-44c3-8de9-860c34a00d81

DATA: type = rw, run = VLIR0, load = CVT;
Adjusted constructors. The constructors are _NOT_ allowed anymore to access the BSS. Rather they must use the DATA segment or the INIT segment. The latter isn't cleared at any point so the constructors may use it to expose values to the main program. However they must make sure to always write the values as they are not pre-initialized.

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.
