per conversation with Ralph and Jeff take out the opal_init_only logic.

This commit moves the initalization/finalization of opal_event and opal_progress
to opal_init/finalize. These were previously init/final in ORTE which is an
abstraction violation. After talking about it we concluded that there are no
ordering issues that require these to be init/final in ORTE instead of OPAL.

I ran the IBM test suite against this commit and it didn't turn up any new
failures so I think it is good to go.

Let us know if this causes problems.

This commit was SVN r14773.
