Fix several issues in the preprocessor:
...
- macro expansion of hexidecimal numbers
- give errors instead of warnings/silence on extra tokens after #endif, #else, etc.
- give errors on reserved macro name use, reuse of argument, and redefinition with different whitespace presence
- detect and give error for all cases of #elif and #else after #else
