 * @return OSHMEM_ERROR Upon other failure.
 *
 * This function invokes the selection process for shmem components,
 * which works as follows:
 *
 * - If the \em sshmem MCA parameter is not specified, the
 *   selection set is all available shmem components.
 * - If the \em sshmem MCA parameter is specified, the
 *   selection set is just that component.
 * - All components in the selection set are queried to see if
 *   they want to run.  All components that want to run are ranked
 *   by their priority and the highest priority component is
 *   selected.  All non-selected components have their "close"
 *   function invoked to let them know that they were not selected.
 * - The selected component will have its "init" function invoked to
 *   let it know that it was selected.
 *
 * If we fall through this entire process and no component is
 * selected, then return OSHMEM_NOT_FOUND (this is not a fatal
 * error).
 *
 * At the end of this process, we'll either have a single
 * component that is selected and initialized, or no component was
 * selected.  If no component was selected, subsequent invocation
 * of the shmem wrapper functions will return an error.
