integer. Fix the argument decoding to treat this as a quad instead of an int. This includes using QUAD_ALIGN and QUAD_SLOTS as necessary. To continue printing IDs in decimal, add a new QuadHex argument type that prints a 64-bit integer in hex, use QuadHex for the existing off_t arguments, repurpose Quad to print a 64-bit integer in decimal, and use Quad for id_t arguments. This fixes the decoding of wait6(2) and procctl(2) on 32-bit platforms.
