An attempt to restrict CPU I/O instructions to targets
where it makes sense. If it does, I'll send the next
series which restrict the I/O address space to X86/AVR.

Based-on: <20210314225308.2582284-1-f4bug@amsat.org>

Philippe Mathieu-Daudé (8):
  softmmu/physmem: Rename io_mem_unassigned -> unassigned_mr
  exec: Extract CPU I/O instructions to "cpu-io.h"
  target: Introduce TARGET_HAS_IOPORT
  qtest/fuzz: Restrict CPU I/O instructions
  qtest/libqos: Restrict CPU I/O instructions
  qtest: Restrict CPU I/O instructions
  monitor: Restrict CPU I/O instructions
  softmmu: Restrict CPU I/O instructions
