Per feedback from https://github.com/open-mpi/ompi/pull/6028, remove
"+ob1" from the sentence to emphasize that it's only IB usage through
openib that is deprecated/superceded (i.e., ob1 is definitely not
deprecated).

It seems in some cases (gcc older than v6.0.0) the __atomic_thread_fence is a
no-op with __ATOMIC_ACQUIRE. This appears to be the case with X86_64 so go
ahead and use __ATOMIC_SEQ_CST for the x86_64 read memory barrier. This should
not cause any performance issues as it is equivalent to the memory barrier
in the hand-written atomics.

Commit 89da9651b inadvertantly #if'ed out both deprecated *and*
removed items from mpi.h. The intent was only to #if out items that
have been *removed* from the MPI specification and leave all items
that are merely deprecated.
This commit also re-orders the deleted typedef+functions to be in the
same order as they are listed in MPI-3.1 chapter 17, just to make
verifying/checking the code easier.
Note that --enable-mpi1-compatibility can still be used to restore
prototypes for the items that have been removed from the MPI
specification (e.g., MPI_Address()).

PR #5450 addresses MPI_IN_PLACE processing for basic collective algorithms.
But in conjunction with that, we need to check for MPI_IN_PLACE in tuned paths
as well before calling ompi_datatype_type_size() as otherwise we segfault.
MPI spec also stipulates to ignore sendcount and sendtype for Alltoall and
Allgatherv operations. So, extending the check to these algorithms as well.

mca_scoll_basic_alltoall() passed (pSync + 1) to barrier function, but
the value of _SHMEM_ALLTOALL_SYNC_SIZE is 1, which made the barrier
function use an invalid memory location. In particular, this location
was not initialized to _SHMEM_SYNC_VALUE, which broke the barrier
algorithm and it did not complete: One PE could read 0 from its peer and
assume the peer already started the barrier, and then write 1 to the
peer. Then, the peer entered the barrier and overwrote the 1 with 0, and
then it waited forever to see '1' in its pSync.
Found with shmem_verifier test suite.
