-Updated the design for sync send MPI calls to use 2 protocol bits for
denoting "sync_send" or "sync_send_ack".
-"Sync_send" is added to the send tag only and is masked out in receives
such that it can be read by the original Recv posted in the send/recv
operation.
-"Sync_send_ack" is sent from the recv callback to the send side. This 0
byte send does not generate a completion entry and instead sends the
message and immediately completes the opal completion in the recv.
-Tag formats ofi_tag_1 and ofi_tag_2 have been updated to include 2
more tag bits per format type due to the reduced protocal bits required
by OMPI.

The call of MPI_Gather with sendbuf and sendtype parameters equal to MPI_IN_PLACE and NULL correspondingly, produces the segmentation fault in the root process.
The problem is that sendtype is used even when sendbuf value is MPI_IN_PLACE. But according to the standard (page 150, line 37), sendtype and sendcount parameters should be ignored in this case.

moving some code from fs/ufs into fs/base. The benefit of this approach is
that fs components that are fundamentally based on posix I/O (and only differ
in some non-posix functionality such as setting stripe size, or which hints
are being supported) can avoid having to replicate the same code over and
over again. First beneficiary is the lustre fs component, but more
are to follow soon.

Intentionally do not mark some MPI-1 function pointer typedefs as
`__mpi_interface_removed__` because we have to use them in prototyping
some MPI-1 functions when `--enable-mpi1-compatibility` is used.

This commit fixes a typo where a bcast is used instead of the intended
collective (barrier).

Note this first and naive implementation does not use the wait_fn callback.

The osc/rdma module did not wait for all pending atomics to complete
before tearing down. This could lead to weird issues as the target
location may no longer be registered or allocated.
This commit also fixes an offset calculation issue in
ompi_osc_get_data_blocking ().

handle the situation where the user requests a non-zero amount
of data but has a zero-size fileview. My instrinct would have been
to return an error code, but according to the test that I used
it should be MPI_SUCCESS and zero bytes. It is definitely better
than segfaulting :-)
THis makes another test from the IBM testsuite pass.

the seek offset calculation did not treat the offset as a multiple
of the etype provided. Fixing this makes some more ibm tests pass.

use an allocator to manage temporary buffers when copying
unmanaged data from GPU buffer to host. This is necessary,
since the buffers have to be pinned for better performance,
which is an expensive operation.

the two_phase compoment does not work with some collective I/O
operations on CUDA buffers due to the data sieving (i.e.
both read and write operations) executed on some buffers, which are
not anticipated in the GPU buffer management of the code.
