Adapted, to the c64 target, the INIT-segment overlay scheme from the apple2 targets.
...
When a program starts running, INIT is moved from one place to another place. Then, INIT's code is executed; and, the first place is re-used for variables. After the INIT code has finished, the second place can be re-used by the heap and the C stack. That means that initiation code and data won't waste any RAM space after they stop being needed.

Implemented a one-character buffer for kbhit() and cgetc().
...
If kbhit() detects that a key is pressed, it fetches and
buffers the character. If cgetc() detects a buffered character,
this one is returned instead of fetching one with the PROM
routine.

* Changed the way that Atmos programs are started.
...
- Put a BASIC-language stub at the beginning.
- Removed the Autostart flag.
Those changes make it easy to give command-line arguments to a program.
* Made the Atmos configure file accept a special symbol definition on ld65's command line. We can use "__RAMEND__" to increase the amount of RAM that's available to programs.

Renamed JUMPTABLE and cleaned up module.cfg.
...
This change was suppsed to fix the issue that the former JUMPTABLE is merked as 'ro' while it is actually written to in several scenarios. When drivers are converted using co65 and then compiled into ROMs the JUMPTABLE isn't copied to RAM and therefore the write operations in question fail.
However unfortunately I didn't succeed in changing that :-( Just setting the former JUMPTABLE to 'rw' broke the drivers. So I placed the DATA segment directly after the former JUMPTABLE segment. This made the drivers converted with co65 work again - obviously after changing libsrc/Makefile:235 from '--code-label' to '--data-label'. But the actual dynamic drivers still didn't work as the former JUMPTABLE wasn't placed as the beginning of the loaded file anymore. That effect could be changed by exchanging src/ld65/o65.c:1391 with src/ld65/o65.c:1394 but doing so broke the drivers again :-((
