The name of `MPI_INTEGER16` obtained using `MPI_TYPE_GET_NAME`
from Fortran program was incorrect (`MPI_INTEGER8` was obtained)
when `INTEGER*16` is not supported by a compiler.
This bug affects only the Fortran binding because `MPI_INTEGER16`
is not defined in `mpi.h` if a compiler does not support it.
This commit add the following Fortran named constants which are
defined in the MPI standard but are missing in Open MPI.
- `MPI_LONG_LONG` (defined as a synonym of `MPI_LONG_LONG_INT`)
- `MPI_CXX_FLOAT_COMPLEX`
- `MPI_C_BOOL`
And this commit also changes the value of the following Fortran
named constant for consistency.
- `MPI_C_COMPLEX`
`(MPI_C_FLOAT_COMPLEX` is defined as a synonym of this)
Each needs a different solution described below.
For `MPI_LONG_LONG`:
The value of `MPI_LONG_LONG` is defined to have a same value
as `MPI_LONG_LONG_INT` because of the following reasons.
1. It is defined as a synonym of `MPI_LONG_LONG_INT` in
the MPI standard.
2. `MPI_LONG_LONG_INT` and `MPI_LONG_LONG` has a same value
for C in `mpi.h`.
3. `ompi_mpi_long_long` is not defined in
`ompi/datatype/ompi_datatype_module.c`.
For `MPI_CXX_FLOAT_COMPLEX`:
Existing `MPI_CXX_COMPLEX` is replaced with `MPI_CXX_FLOAT_COMPLEX`
bacause `MPI_CXX_FLOAT_COMPLEX` is the right name defined in MPI-3.1
and `MPI_CXX_COMPLEX` is not defined in MPI-3.1 (nor older).
But for compatibility, `MPI_CXX_COMPLEX` is treated as a synonym
of `MPI_CXX_FLOAT_COMPLEX` on Open MPI.
For `MPI_C_BOOL`:
`MPI_C_BOOL` is newly added. The value which `MPI_C_COMPLEX` had
used (68) is assinged for it because the value becomes no longer
in use (described later) and it is a suited position as a datatype
added on MPI-2.2.
For `MPI_C_COMPLEX`:
Existing `MPI_C_FLOAT_COMPLEX` is replaced with `MPI_C_COMPLEX`
and `MPI_C_FLOAT_COMPLEX` is changed to have the same value.
In other words, make `MPI_C_COMPLEX` the canonical name and
make `MPI_C_FLOAT_COMPLEX` an alias of it.
This is bacause the relation of these datatypes is same as
the relation of `MPI_LONG_LONG_INT` and `MPI_LONG_LONG`, and
`MPI_LONG_LONG_INT` and `MPI_LONG_LONG` are implemented like that.
But in the datatype engine, we use `ompi_mpi_c_float_complex`
instead of `ompi_mpi_c_complex` as a variable name to keep
the consistency with the other similar types such as
`ompi_mpi_c_double_complex` (see George's comment in open-mpi/ompi#1927).
We don't delete `ompi_mpi_c_complex` now because it is used in
some other places in Open MPI code. It may be cleand up in the future.
In addition, `MPI_CXX_COMPLEX`, which was defined only in the Open MPI
Fortran binding, is added to `mpi.h` for the C binding.
This commit breaks binary compatibility of Fortran `MPI_C_COMPLEX`.
When this commit is merged into v2.x branch, the change of
`MPI_C_COMPLEX` should be excluded.
On Cray, PR #1846 introduced a double free
situation which led to all kinds of random memory
corruption problems.
This commit fixes this problem.

This commit expands the OPAL_THREAD macros to include 32- and 64-bit
atomic swap. Additionally, macro declararations have been updated to
include both OPAL_THREAD_* and OPAL_ATOMIC_*. Before this commit the
former was used with add and the later with cmpset.

This commit adds opal_using_threads() protection around the atomic
operation in OBJ_RETAIN/OBJ_RELEASE. This resolves the performance
issues seen when running psm with MPI_THREAD_SINGLE.
To avoid issues with header dependencies opal_using_threads() has been
moved to a new header (thread_usage.h). The OPAL_THREAD_ADD* and
OPAL_THREAD_CMPSET* macros have also been relocated to this header.
This commit is cherry-picked off a fix that was submitted for the v1.8
release series but never applied to master. This fixes part of the
problem reported by @nysal in #1902.

The max inline send size on a queue pair is not available until after
the endpoint is connected. Before this commit the send flags
(including the inline flag) were set before this value was
initialized. This commit moves setting the send_flags down to
mca_btl_openib_put_internal which is only called after the endpoint is
connected. This fixes a bug when using osc/rdma.
