Since the oob and connections systems do not work the same way they
did in older versions of Open MPI these operations are no longer
necessary. At best they do nothing and at worst they hurt performance
by making us enter the event library more often in opal_progress().

Using MPI_MINLOC or MPI_MAXLOC with the following data types
leads to data corruption:
* MPI_DOUBLE_INT
* MPI_LONG_INT
* MPI_SHORT_INT
* MPI_LONG_DOUBLE_INT
Detect this print a error message and abort.
This workaround should be removed once the following issue is resolved:

When Java bindings are used, MPI_Init() is not invoked
by the main thread, and this causes some keys being destructed twice.
Reset the per thread values to NULL in order to correctly handle this

* Add an MCA parameter to combine stdout and stderr at the source
- `iof_base_redirect_app_stderr_to_stdout`
* Aids in user debugging when using libraries that mix stderr with stdout

* Similar to `orte_map_stddiag_to_stderr` except it redirects `stddiag`
to `stdout` instead of `stderr`.
* Add protection so that the user canot supply both:
- `orte_map_stddiag_to_stderr`
- `orte_map_stddiag_to_stdout`

- This allows the following MCA option to have an impact on the
framework verbose output as well.
* `-mca mca_base_verbose stdout`

* Adds a parameter to adjust the method used by libevent.
- Matches that of the libevent2022 component.

MPI_Allgatherv with MPI_IN_PLACE reads data from wrong location.
They were locating the MPI_IN_PLACE send buffer as
```c
send_buf = (char*)rbuf;
for (i = 0; i < rank; ++i) {
send_buf += ((ptrdiff_t)rcounts[i] * extent);
}
```
when it should be
```c
send_buf = (char*)rbuf;
send_buf += ((ptrdiff_t)disps[rank] * extent);
```
because disps[] specifies where things are in the v-style buffers.

Note: since the discovered cpus are filtered against this list, #slots will be set to the #cpus in the list if no slot values are given in a -host or -hostname specification.

when a file is opened a second time for shared file pointer operations,
avoid setting the create and exclusive flag.

it looks like disabling the lazy_open flag for sharedfp components
revealead a bug that lead to a crash in file_close in some tests. Make
sure the SHAREDFP_IS_SET flag is correctly set (and not overwritten again),
and we use that to avoid a double-free of the communicator.

* The AC_LANG_PROGRAM macro adds the `main()` so it is erroneous
to add it to the test program.
* This was detected with the XL compilers which will fail to
build the program in this situation. The GNU compiler does not
error out or warn, but successfully compiles the program.
