* 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.

Revert the logic of io_ompio_sharedfp_lazy_open. The user now has to explicitely
disable shared fp in order for the structures not to be allocated.
Otherwise, resetting the shared fp e.g. in case the file was opened
in append mode will not work correctly, the code could deadlock.

Fixes a bug reported on the mailing list. ompio did only reposition the individual
file pointer when the file was opened in append mode. Set the shared file
pointer also to point to the end of the file, similarly to the individual
file pointer.

This commit fixes a bug in the registration of the num_threads MCA
variable. The variable is of type int and was being registered as
a boolean.
