9dbab31d9eb710b433f93e9e35962fbfd29f4c3f replay: allow runstate shutdown->running when replaying trace
When replaying a trace, it is possible to go from shutdown to running
with a reverse-debugging step. This can be useful if the problem being
debugged triggers a reset or shutdown.
This can be tested by making a recording of a machine that shuts down,
then using -action shutdown=pause when replaying it. Continuing to the
end of the trace then reverse-stepping in gdb crashes due to invalid
runstate transition.
Just permitting the transition seems to be all that's necessary for
reverse-debugging to work well in such a state.
