dae3c9447c btl/ofi: add scalable endpoint support.
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).

b6e07bfac6 btl/ofi: change required mr mode bits.
FI_MR_UNSPEC is not supposed to be used beyond ofi version 1.5. This
commit replaces FI_MR_UNSPEC with the new FI_MR_BASIC mode bits
(FI_MR_PROV_KEY | FI_MR_ALLOCATED | FI_MR_VIRT_ADDR).

The btl functionality remains the same.

f34a73af70 btl/ofi: handles FI_EINTR properly.
OFI sockets provider will sometime return FI_EINTR. Apparently this flag
does not exist in OFI version 1.5. This commit added an ifdef check.

6efb8069ec new btl/ofi: RDMA only btl using libfabric.
This commit added new transport layer to be used with osc rdma module.
This BTL provides put, get, atomic and fetch atomic operations. It can
be used with multiple hardware vendors as long as they have their
provider under Libfabric and have the right capabilities.
