09e50d433d * 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.

970af0cdb2 Swapped the locations of a constructor and a destructor in a source file. 
The constructor now is first.

Used a more expressive literal zero.

2c975d3642 Create static drivers directly from source files. 
Up to now static drivers were created via co65 from dynamic drivers. However there was an issue with that approach:

The dynamic drivers are "o65 simple files" which obligates that they start with the 'code' segment. However dynamic drivers need to start with the module header - which is written to. For dynamic drivers this isn't more than a conceptual issue because they are always contain a 'data' segment and may therefore only be loaded into writable memory.

However when dynamic drivers are converted to static drivers using co65 then that issue becomes a real problem as then the 'code' segment may end up in non-writable memory - and thus writing to the module header fails.

Instead of changing the way dynamic drivers work I opted to rather make static driver creation totally independent from dynamic drivers. This allows to place the module header in the 'data' segment (see 'module.mac').

d6c3bd29ac 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 :-((

eadd7c7ade Patch by Greg King: The Oric Atmos graphics driver tries to be both a 
black-and-white driver and a color-palette driver, at the same time.  That
cannot work on the Oric's architecture.  This patch makes it be only a
black-and-white driver.

4aa00e84e1 Removed tgi_load() and all corresponding infrastructure. The idea behind tgi_load() was to be able to describe a TGI mode in a target-neutral way by resolution and colordepth. However it turned out that there arn't any cc65 targets sharing any resolution. As a result the only working target-independent approach for a TGI program is to call tgi_loaddriver(tgi_stddrv); and then look up the resolution provided - and to adapt to that resolution.
