Fixed a problem in line info generation: Recorded token lists emitted the
tokens using the standard ASM line info, overwriting the existing one from the
real source line. Since this info was lost, and couldn't be recovered, the
original source location was omitted in error messages.
Added a new attribute IMPORT to the CONDES definition of the FEATURES section.
If this attribute is defined, an import for the given symbol is added to the
module that contains the condes declaraction. Using this feature, it is
possible to force linkage of a module that contains an export for the symbol.

Fixed several aspects of the GEOS CONIO implementation:
- cputc was drawing at the wrong position, therefore one line had to be removed as a workaround.
- chline, cvline were drawing one pixel to large lines.
- cclear was drawing an in both directions one pixel to big rect.
- the cursor was drawn at wrong times at wrong places in a wrong size.

On Cywin with its (too) expensive fork() this change cuts down minimal re-build times from nearly 2 minutes to approx. 6 seconds. Additionally it looks in all directories in the first list for "override" files, not just in one.

The 128+x character codes were very likely intended to be interpreted by cputs and translated into explicit drawing of short lines. However there was no code to do so at all. Given that the emulation of a characterbased API on a graphics system isn't the premier choice for a sophisticated UI it doesn't seem appropriate to invest into actually implementing the approach described above. Therefore I just replaced the character codes with a '+'.

Implemented __syschdir on CBM. As getcwd returns a cached directory any direct access to __curunit would cause inconsistencies. Therefore __curunit was renamed to curunit to prohibit user access.

I wasn't aware that the unit numbers in the ProDOS device list contain device type identifiers in the low nibble. So if we can't use the device list entries as-is we can as well present the high nibble as low nibble to the user thus providing more meaningful device numbers.

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.

Adjusted according to the recently updated readdir() doc that now says:
"On several platforms, namely the CBMs and the Atari, the disk drives get confused when opening/closing files between directory reads. So for example a program that reads the list of files on a disk, and after each call to readdir, opens the file to process it, will fail.
Possible solutions are reading the directory into memory before processing the file list, or to reset the directory by seeking to the correct position after opening/closing a file:
seekdir (DIR, telldir (DIR));
Platforms known to work without problems are: Apple."

Added somewhat more complex demo. It looks for emdrivers in the current directory and tries to load them until one loads successfully. In that case it "streams" its overlay files into extended memory. Finally it loads its overlays from extended memory (or disk) and calls into them.
