These three patches introduce a new system emulation binary qemu-qmp-*
that does nothing but start a QMP monitor (via systemd activation
protocol if possible, otherwise on stdio).  The idea is that the
creation of the machine would happen through new commands such as
machine-set, accel-set, etc.

Patches 1 and 2 simply avoid that {'execute':'quit'} crashes; that's
more or less the extent of my testing.

Paolo Bonzini (3):
  migration: allow calling migration_shutdown without a prior
    initialization
  net: initialize global variables early
  introduce qemu-qmp-*
