Cleanup few errors associated with tool support

Properly mark/detect that a daemon sourced the event broadcast to avoid
reinjecting it into the PMIx server library. Correct the source field
for the event notify call on launcher ready.

Update event notification for tool support
Deal with a variety of race conditions related to tool reconnection to a
different server.
