This commit add support for scalable endpoint to enhance multithreaded application performance. The BTL will detect the support from ofi provider and will fallback to normal usage of scalable endpoint is not supported. NEW MCA parameters: - mca_btl_ofi_disable_sep: force the btl to not use scalable endpoint. - mca_btl_ofi_num_contexts_per_module: number of communication context to create (should be the same as number of thread).
