Fix memory-safety bugs in the ispell/hunspell dictionary loader. Allocate CompoundAffix with room for its terminator, initialize the old-format flag buffer before NIAddAffix(), and reject incomplete or missing Hunspell AF aliases. None of these errors would be likely to trigger on real dictionary files, accounting for the lack of previous reports; but they're certainly bugs.
