Jeff Squyres fca193d316 MPI extensions: build extensions by default

* affinity: will build unless disabled.
* cr: will build if FT is enabled, unless it is disabled.  It will
  also complain/abort if you --with-mpi-ext=cr, but FT is disabled.
* example: will only build if --with-mpi-ext=example (and .ompi_ignore
  is removed)

This extension provides a single new function, OMPI_Affinity_str(),
that takes a format value and then provides 3 prettyprint strings as
output:

fmt_type: is an enum that tells OMPI_Affinity_str() whether to use a
resource description string or layout string format for ompi_bound and
currently_bound output strings.

ompi_bound: describes what sockets/cores Open MPI bound this process
to (or indicates that Open MPI did not bind this process).

currently_bound: describes what sockets/cores this process is
currently bound to (or indicates that it is unbound).

exists: describes what processors are available in the current host.

See OMPI_Affinity_str(3) for more details.
