Ralph Castain e96b5f486f Reorganize the opal interface code in opal/util/if.c per prior emails and telecon discussions. Move the interface discovery code into a framework so that configuration logic can separate it out (instead of the prior #if-#else confusion).
All interface APIs for accessing the info remain unchanged in opal/util/if.c.

This has been tested on Mac, Linux, and NetBSD. Nobody else seemed interested in testing it, so there may be some future problems revealed as people try it on other OSs.

This commit was SVN r23743.
