Fixes PR https://github.com/open-mpi/ompi/pull/1687
The code that sets OPAL_HAVE_WORKING_EVENTOPS for internal libevent
was executed even if the external libevent component was configured.
As the result libevent progress wasn't called in opal_progress which
for example caused ring_c to hang when pml/ob1 was used.
Architecture is set by the ompi layer *after* job startup, so the key cannot
have the "pmix" prefix since optimizations in open-mpi/ompi@01a653d50a
otherwise architecture cannot be retrieved
Based on current implementation it is faster to use a blocking
send than the non-blocking version. Switch the exchange function
used in the barrier to use the blocking version combined with
the non-blocking version of the receive.
This is similar to open-mpi/ompi@223d75595d
It is possible for the start call to complete the requests. For this
reason the module rdma_frag field should be filled in before start is
called. If the request completes the completion callback will reset
the rdma_frag field to NULL. Fixes a bug discovered by @tkordenbrock.

On start we were not correctly resetting all request fields. This was
leading to a double-completion on persistent receives. This commit
updates the base start code to reset the receive req_bytes_packed and
the send request convertor.

This commits changed rand(3) and family in libevent to use internal
random function provided in opal to prevent pertubing user's random seed.

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.
