WinCMOC (M6809 C Compiler) Code

Now late binding libgraph to conio in order to remove overhead for text only programs. Still more work to be done. It should remove 5-10K from a text only bin.

Added tiny sprintf versions (swritef) which can be used to reduce bin sizes.

"_" namespaced non-standard conio functions.

Fixed the LWASM slowness issue. For large ASM files (>1000), I use the 'forwardrefmax' pragma, which means all branches will be long. This doesn't effect projects which are broken up into small objects.

Experimenting with some peephole optimizations. Trying to reduce the bin sizes.

AMOC now removes unneeded symbols from files, reducing the final lib by 100kb+. Speeds up linking too.

New asm 6809 preprocessor is called "AMOC". Makes sense to me.

Found a bug in the heap_malloc.c. Fixed and tested. I'll test until its 100% perfect!

Added _setvideomode & _getvideoconfig. Cleaned up libgraph a little.

Added rpncalc.c example from Brian K. Holman
Fixed startup to allow function calls from global space.
