Josh Hursey 9971bc9d95 Merge in the mca_base_select changes per RFC:
http://www.open-mpi.org/community/lists/devel/2008/04/3779.php

{{{
svn merge -r 18276:18380 https://svn.open-mpi.org/svn/ompi/tmp-public/jjh-mca-play .
}}}

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.

This commit was SVN r18381.
