We moved the instance of smo::Mind to global scope. I suppose we'll
only support one instance of Mind per SMO process at least for now.
We now track the state of Mind threads' JOLT-waiting. This allows us
to centralize the Mind thread shutdown logic. Mind::finalizeReq()
now takes care of all Mind thread shutdown state logic by tracking
whether Mind threads need to be JOLTed first before being told to
exit.
This allows us to execute an op on all mind threads without having
to repeatedly write loops. We've implemented wrappers to handle
start, pause, resume, exit and JOLT sequences.
Mrntt now has the event loop structure required to orderly shut itself
down when it itself generates an exception. We can now post a message
within the catch{} blocks for Mrntt's event loop, telling Mrntt
to shut down the Mind threads and then shut itself down.
We also split the code to initialize threads etc out of mrntt and
put it into the Mind:: namespace.
