John KessenichPreprocessor: Rationalize, simplify, and correct the stack of input sources and their tokenization. This included - consistently dealing with EOF and its effect on error recovery (bug 11444, #1) - turning a simulated OO hierarchy of function pointers and typecasting into a real C++ class hierarchy - correctly handling '\' everywhere, in all classes of tokens, as a layer before preprocessing itself - conditionally handling '\n' in macro expansion input, depending on whether it is in a macro expression or not - delete some unused "memory cleanup" codefcb4ed05
