Unfortunately, we assign the jobid during the plm.spawn procedure - which means it happens -after- control of the job has passed out of the range of mpirun (or whatever program is spawning the job), so it is too late for that main program to register a callback function. If the main program registers tha callback -after- we return from plm.spawn, then it (a) cannot get a callback for failed-to-start, and (b) will miss the callback if a proc aborts in the time between job launch and the call to errmgr.register_callback.
This commit fixes the problem by adding callback-related fields to the orte_job_t object. Thus, the main program can specify what job states should initiate a callback, what function is to be called, and what data is to be passed back by simply filling in the orte_job_t fields prior to calling plm.spawn.
Also, fully implement the "copy" function for the orte_job_t object.
NOTE: as a result of this change, the errmgr.register_callback API may no longer be of any value.

Any components not in the trunk, but in one of the effected frameworks *must* be
updated. Contact the list, look at the RFC, or look at the diff for how to do this.
Sorry for the early commit of this, but I wanted to get it in today (per RFC) and
didn't know if I would have a chance later today.
