The realmode test is compiled in 16-bit mode, hence it uses a
cut-and-pasted version of the mini C library and is still printing
to the old debug port at 0xf1.  Use the serial port instead.

v1->v2: set serial_inited, both in the original and the copied code [Gleb]

Paolo Bonzini (3):
  realmode: restore DF at exit from exec_in_big_real_mode
  io: only initialize serial port once
  realmode: print to serial port
