Just to be clear -- the command still exists and works.
What changed is how gdb reports it.  It used to be that you would get:

    -exec-continue
    ~"Stopped due to shared library event."
    *stopped

Now you will get:

    -exec-continue
    *stopped,reason="solib-event",[more stuff]

I can even restore the old output if you really need it; though I'd
prefer we just keep on with a more purely MI solution.
