Subject: [PATCH] This adds into the system a utility for detecting what kind
 of system we are on. The utility provides a global variable ompi_system_info
 that contains information on the operating system, release and version,
 machine architecture, and network node name. I'll provide additional
 documentation via Doxygen once I figure out how to put it into the .h file.

Code was reviewed by Jeff - thanks Jeff!

This commit was SVN r1141.
