Mostly missing headers, explicit parentheses and new prototypes. Some Caveats: * I haven't compile-tested the SVR4 getpty file, it might need another tweak * There were operator precedence bugs in TermPrimCursor.c and TermPrimRender.c (^ vs. !=). This might change behaviour, but at least I haven't experienced any crashes ... * This adds a little more dependencies for include ordering, but unless we want to play the "headers that include headers that include headers..." game, this is unavoidable.
