Still in the "needs to be done" category:
* mapping/ranking/binding options aren't correctly supported
* if the DVM encounters some errors (e.g., not enough resources for the job), the resulting error is globally set and impacts any subsequent job submission

Unlike "orterun", "prun" is a PMIx-only program that discovers the DVM connection instead of requiring that we explicitly provide it. Only build "prun" if PMIx v2.x is available.
This gets the DVM working again, but still is showing problems for multiple executions. I'll detail those in a separate issue. Thus, the DVM should still be considered "broken".

* Even if we are only launching one app context, we might call spawn
later and the remote groups might want their global rank information.

* Resolves#3705
* Components should link against the project level library to better
support `dlopen` with `RTLD_LOCAL`.
* Extend the `mca_FRAMEWORK_COMPONENT_la_LIBADD` in the `Makefile.am`
with the appropriate project level library:
```
MCA components in ompi/
$(top_builddir)/ompi/lib@OMPI_LIBMPI_NAME@.la
MCA components in orte/
$(top_builddir)/orte/lib@ORTE_LIB_PREFIX@open-rte.la
MCA components in opal/
$(top_builddir)/opal/lib@OPAL_LIB_PREFIX@open-pal.la
MCA components in oshmem/
$(top_builddir)/oshmem/liboshmem.la"
```
Note: The changes in this commit were automated by the script in
the commit that proceeds it with the `libadd_mca_comp_update.py`
script. Some components were not included in this change because
they are statically built only.

There can be multiple [heap] consecutively in proc/<pid>/maps,
and there's no room between them.
Don't use a hole after the first [heap] is there's another [heap]
immediately after it.
This code would fail to find the last [heap] if there were multiple
[heap] interleaved with non-heap VMA, but our kind "after heap"
wouldn't be meaningful anymore anyway.

always re-initialize vmhole *before* mca_base_component_var_register()
otherwise the vmhole gets NULL'ified if orte is initialized a second time.
that typically occurs when Open MPI is configure'd with --disable-dlopen
and the app does MPI_T_init_thread(); MPI_T_finalize(); MPI_T_init_thread();

It turns out that the approach of having the HNP do the
fork/exec of MPI ranks on the head node in a SLURM environment
introduces problems when users/sysadmins want to use the SLURM
scancl tool or sbatch --signal option to signal a job.
This commit disables use of the HNP fork/exec procedure when
a job is launched into a SLURM controlled allocation.
