s/IRQ_OFFSET/T_IRQ0/: it's a trap number, not an irq number.
move the SYSCALL number up, so does not overlap the IRQ traps.

Add serial port input/output.
Delete parallel port output.
Works well with qemu -nographic mode.

run without lapic and ioapic, if they are not present
if no lapic available, use 8253pit for clock
now xv6 runs both on qemu (uniprocessor) and bochs (uniprocessor and MP)
