Commit Message

modules/wreck: improve reactor exit condition in wrexecd

Switch to completion references to determine when to exit reactor
loop, instead of repeatedly checking for all tasks exited and IO
closed on every event.

Task exit, stdout, stderr, and any other condition that should
prevent exit from the reactor loop take a "completion reference"
until they're exit condition is met, at which point the reference
is removed. When the last ref is removed, flux_reactor_stop() is
called.

This allows more deterministic exit from the reactor loop (at which
pojnt the job state will transition to "complete") without requiring
*all* watchers to be stopped, which is an intractable problem since
plugins could install watchers, signalfd watcher would need to be
stopped manually, etc.
