Adds mapping of the MPI Fortran pair types (2INTEGER, 2REAL, 2DBLPREC)
to the corresponding hcoll dtypes.

MPI_Sizeof related stuff has been moved to their own files.
Remove MPI_Sizeof from Fortran interfaces when it cannot be built
(e.g. stock gcc 4.8 on CentOS 7)

recvreq->req_recv.req_base.req_type should always be set before invoking
MCA_PML_OB1_RECV_REQUEST_INIT(recvreq, ...) otherwise, the previous type
might be set, and you could end up with MPC_PML_REQUEST_IMPROBE when
MCA_PML_REQUEST_RECV is expected.
Thanks Chris Pattison for the report and test case.
Fixesopen-mpi/ompi#2275
* If an error is detected internal to libnbc (e.g., PML truncation error)
this patch makes sure that the request is completed and the `MPI_ERROR`
field is set approprately.
* Make an attempt to cleanup outstanding requests before returning.
- This is a "best attempt" since not all PMLs support canceling requests.
In order to optimize for MPI_IN_PLACE, data is sent from the receive buffer.
consequently, it should be sent with the receive type and count.
Thanks Josh Hursey for the report and test case

- pass field_mask to ucp_init().
- use non-blocking disconnect.
- recv() with pre-allocated request.
- call opal_progress() from iprobe() and improbe().
- use shift pattern in connect/disconnect.
Multiple conduits can exist at the same time, and can even point to the same base transport. Each conduit can have its own characteristics (e.g., flow control) based on the info keys provided to the "open_conduit" call. For ease during the transition period, the "legacy" RML interfaces remain as wrappers over the new conduit-based APIs using a default conduit opened during orte_init - this default conduit is tied to the OOB framework so that current behaviors are preserved. Once the transition has been completed, a one-time cleanup will be done to update all RML calls to the new APIs and the "legacy" interfaces will be deleted.
While we are at it: Remove oob/usock component to eliminate the TMPDIR length problem - get all working, including oob_stress
Instead of ompi_datatype_get_extent(), use ompi_datatype_get_true_extent()
to get the local and remote lower bound. For derived types like
subarray, true_lb is the correct offset for RDMA operations.
Instead of ompi_datatype_get_extent(), use ompi_datatype_get_true_extent()
to get the origin and target lower bound. For derived types like
subarray, true_lb is the correct offset for RDMA operations. Also,
instead of the extent use the size of the datatype.
As long as it is illegal to call MPI_T_init_thread() after MPI_Finalize(),
be gentle and release as much memory as possible in MPI_Finalize().
opal_cleanup() will be invoked again by the OPAL destructor, but will
do nothing since classes was set to NULL
