0ee9b2e446 Changed run location of INIT segment.
So far the INIT segment was run from the later heap+stack. Now the INIT segment is run from the later BSS. The background is that so far the INIT segment was pretty small (from $80 to $180 bytes). But upcoming changes will increase the INIT segment in certain scenarios up to ~ $1000 bytes. So programs with very limited heap+stack might just not been able to move the INIT segment to its run location. But moving the INIT segment to the later BSS allows it to occupy the later BSS+heap+stack.

In order to allow that the constructors are _NOT_ allowed anymore to access the BSS. Rather they must use the DATA segment or the new INITBSS 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.

6217f8fa3a Made the Commodore version of exec() work in programs that are so big that they load into all of BASIC RAM.
The function won't cause an "out of memory" error.

Greg King
e63bf1cde1 Used a library-reference method to calibrate lightpen drivers.
The mouse reference is a pointer.  If it's NULL, the driver uses a default.  If it's non-NULL, then it points to a function that the driver can call.  That function will adjust the driver's calibration value.  It could ask the user to adjust the pen; or, it could read a file that holds a value from a previous calibration.

Application writers can choose how it's done: a function that's provided by the library, a custom function, or nothing.

008b4c4e1d Replaced whole bunch for Makefiles with a single generic Makefile.
- No complex shell logic.
- "Source file shadowing" for all targets via vpath.
- Dependency handling.
- True incremental build.
- Don't write into source directories.
- Easy cleanup by just removing 'wrk'.

300817702f initcwd will be called from the upcoming __syschdir so it has to be moved out of the INIT segment - and so it doesn't make sense anymore to keep devicestr as separate module anymore as the integration with initcwd allows to omit the jmp from the latter to the former.

942c0b6b2f Choose another way to fix the issue from r5804: When parsing the directory
name, add a file mask, so the result is "$0:*" or similar. When specified like
this, the drive accepts the r/o specifier ",R" so we don't have to complicate
the code in open().
