waltje 23fcf833b4 Change to not allow configured memory size to go over machine's limit (fixes #25.) 
Lots of cleanup changes all over to fix the constness of strings [again].
Some cleanups in config.c to remove old stuff.

* spanning the era between 1981 and 1995.
*
* This file is part of the VARCem Project.
