The 2 sided communication support is added for non-tagmatching provider
to take advantage of this BTL and PML OB1. The current state is
"functional" and not optimized for performance.
Two sided support is disabled by default and can be turned on by mca
parameter: "mca_btl_ofi_mode".

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).

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.
