Ralph Castain 9e0bb6ae28 Revert r26600 and r26601 for a couple of reasons:
1. they modified the OMPI-ORTE interface, which is something I promised to avoid doing unless absolutely necessary, and

2. the framework ident is already in the component name key provided to the modex db. What is missing is the project ident, but as Jeff and I discussed last week, we really need to add that field to the component struct anyway to avoid multi-project collisions on framework names. That will be done over the next couple of weeks as a separate effort.

This commit was SVN r26613.

The following SVN revision numbers were found above:
  r26600 --> open-mpi/ompi@5ba4deff07
  r26601 --> open-mpi/ompi@0e3094c318
