Add new function opal_get_num_processors() that will return the number of processors on the local host. Does the Right thing in POSIX environments (to include a special case for OS X), and will shortly do the Right Thing for Windows (this commit includes a change to configure, so I wanted to get that in before the US workday -- the Windows code can some shortly because it won't involve configury changes). This commit was SVN r13506. The following Trac tickets were found above: Ticket 853 --> https://svn.open-mpi.org/trac/ompi/ticket/853
