Hi !
It would nice to have some feedback about this solution.

the startup fsm.
It's bit like what Markus proposed in december (hence the name), only it

phase_until() is implemented in vl.c and is meant to be used
to make startup progress up to a specified phase being reached().
At this point, no behavior change is introduced: phase_until()
only supports a single double transition corresponding
to the functionality of qmp_exit_preconfig():
