* 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.

This commit recategorizes several mpirun arguments,
and moves the information for mpirun --help arguments
to the bottom of the general help message. I also
added the OPAL_CMD_LINE_OTYPE field to two commands
that were missed initially because they were not
in the same area as the others.

This commit modifies the output from the mpirun --help
command. The options have been split into groups, to
make the output smaller and more readable. The groups
are: general, debug, output, input, mapping, ranking,
binding, devel, compatibility, launch, dvm, and
unsupported. There is also a special "full" command
that can be used to get the old behaviour of printing
out all of the options. Unsupported options may only
be seen with this full output.
This commit also adds a special case for the help
argument. It makes it possible for the user to
enter 0 or 1 arguments instead of having to always
enter an argument. This defaults to printing out
the "general" help options so the user can then
see what help arguments there are.

onto the backend daemons. By default, let mpirun only pack the app_context
info and send that to the backend daemons where the mapping will
be done. This significantly reduces the computational time on mpirun as it isn't
running up/down the topology tree computing thousands of binding
locations, and it reduces the launch message to a very small number of
bytes.
When running -novm, fall back to the old way of doing things
where mpirun computes the entire map and binding, and then sends
the full info to the backend daemon.
Add a new cmd line option/mca param --fwd-mpirun-port that allows
mpirun to dynamically select a port, but then passes that back to
all the other daemons so they will use that port as a static port
for their own wireup. In this mode, we no longer "phone home" directly
to mpirun, but instead use the static port to wireup at daemon
start. We then use the routing tree to rollup the initial
launch report, and limit the number of open sockets on mpirun's node.
Update ras simulator to track the new nidmap code
Cleanup some bugs in the nidmap regex code, and enhance the error message for not enough slots to include the host on which the problem is found.
Update gadget platform file
Initialize the range count when starting a new range
Fix the no-np case in managed allocation
Ensure DVM node usage gets cleaned up after each job
Update scaling.pl script to use --fwd-mpirun-port. Pre-connect the daemon to its parent during launch while we are otherwise waiting for the daemon's children to send their "phone home" rollup messages

Add ability to pass DVM URI purely via environment
to simplify invocation from command-line (e.g., start dvm,
export URI, mpirun w/o needing to add `--hnp` arg).
If user passes both envvar *and* cmdline, the cmdline wins.

Set the orte_bound_at_launch MCA variable. This resolves a launch
performance bug when using aprun to launch Open MPI processes. If
this variable is not set it can take minutes longer to launch with
high ppn.

Cleanup a typo, and remove no longer needed MCA params for hetero nodes and hetero apps. Hetero nodes will always be automatically detected. We don't support a mix of 32 and 64 bit apps
Modify the orte_node_t to use orte_topology_t instead of hwloc_topology_t, updating all the places that use it. Ensure that we properly update topology when we see a different one on a compute node.

Revamp the event notification integration to rely on the PMIx event chaining and remove the duplicate chaining in OPAL. This ensures we get system-level events that target non-default handlers.
Restore the hostname entries for MPI-level error messages, but provide an MCA param (orte_hostname_cutoff) to remove them for large clusters where the memory footprint is problematic. Set the default at 1000 nodes in the job (not the allocation).

Fine tuning of flux component
Fix a few minor issues with the initial cut:
* Job id could be obtained from the PMI kvsname like SLURM,
but simpler to getenv (FLUX_JOB_ID)
* Flux pmi-1 doesn't define PMI_BOOL, PMI_TRUE, PMI_FALSE
* Flux pmi-1 maps the deprecated PMI_Get_kvs_domain_id() to
PMI_KVS_Get_my_name() internally, so just call that instead.
* Drop residual slurm references.
Add wrappers for PMI functions so that if HAVE_FLUX_PMI_LIBRARY
is not defined, the component can dlopen libpmi.so at location
specified by the FLUX_PMI_LIBRARY_PATH env variable, which adds
flexibility. If HAVE_FLUX_PMI_LIBRARY is defined, link with
libpmi.so at build time in the usual way.
Update configury for flux component
Update m4 so the configure options work as follows:
--with-flux-pmi
Build Flux PMI support (default: yes)
--with-flux-pmi-library
Link Flux PMI support with PMI library at build
time. Otherwise the library is opened at runtime at
location specified by FLUX_PMI_LIBRARY_PATH environment
variable. Use this option to enable Flux support when
building statically or without dlopen support (default: no)
If the latter option is provided, the library/header is located at
build time using the pkg-config module 'flux-pmi'. Otherwise there
is no library/header dependency.
Handle the case where ompi is configured with --disable-dlopen
or --enable-statkc. In those cases, don't build the component
unless --with-flux-pmi-library is provided.
It is fatal if the user explicitly requests --with-flux-pmi but
it cannot be built (e.g. due to --disable-dlopen).
Add a schizo/flux component
Update schizo/flux component
Eliminate slurm-specific usage cases.
Since the module is only loaded if FLUX_JOB_ID is set, there are
only two cases to handle:
1) App was launched indirectly through mpirun. This is not yet
supported with Flux, but hook remains in case this mode is supported
in the future.
2) App was launched directly by Flux, with Flux providing
CPU binding, if any.
Fix up white space in pmix/flux component
Drop non-blocking fence from pmix:flux component
The flux PMI-1 library is not thread safe, therefore
register a regular blocking fence callback instead of the
thread-shifting fencenb().
pmix/flux component avoids extra PMI_KVS_Gets
Keys stored into the base cache under the wildcard
rank are not intended to be part of the global key namespace.
These keys therefore should not trigger a PMI_KVS_Get() if they
are not found in the cache.
Minor pmix/flux component cleanup
pmix/flux: drop code for fetching unused pmix_id
pmix/flux: err_exit must return error
Problem: in flux_init(), although 'ret' (variable holding
err_exit return code) is initialized to OPAL_ERROR, the
variable is reused as a temporary result code, so if there are
some successes followed by a failure that doesn't set 'ret',
flux_init() could return success with PMI not initialized.
Ensure that a "goto err_exit" returns OPAL_ERROR if 'ret'
is not set to some other error code.
pmix/flux: don't mix OPAL_ and PMI_ return codes
Problem: flux_init() can return both PMI_ and OPAL_ return
codes. Although OPAL_SUCCESS and PMI_SUCCESS are both defined
as 0, other codes are not compatible.
Ensure that flux_init() consistently uses 'rc' for PMI_
return codes and 'ret' for OPAL_ return codes.

Note that this cannot be used for MPI performance testing. It is really only useful for ORTE scaling tests. It also only works with the rsh/ssh launcher.
If requested, obtain stacktraces for each application process and report it to stderr upon timeout
stack traces: minor improvements
- Also include the hostname and PID of the each process for which
we're sending the stack traces (vs. just including the ORTE process
name)
- Send a specific error message if we couldn't find "gstack" in the
$PATH (e.g., on OS X)
- Send a sepcific error message if gstack fails to run
- Print a message that obtaining the stack traces may take a few
seconds so that users don't wonder what's happening

This reverts commit open-mpi/ompi@f7257a8310.
Ensure that we properly cleanup the session directory tree. Prior code had issues with symlinks, especially if the file that the link points to was already removed as we traverse the tree. Also found that the dirent checks for directory type weren't fully portable, and so fall back to the stat-based approach which is known to be portable.
Fix singularity singletons by detecting we are in a container and properly setting the pmix selection to pick the isolated component. Remove a stale restriction blocking use of the sm btl
* provide a more reliable way of determining that a process is a singleton by leveraging the schizo framework. Add new components for slurm, alps, and orte to detect when we are in a managed environment, and if we have been launched by mpirun or a native launcher. Set the correct envars to control ess and pmix selection in each case.
* change the relative priority of the pmix120 and pmix112 components to make pmix120 the default
* fix singleton comm-spawn by correctly setting the num_apps field of the orte_job_t created by the daemon - this fixes a segfault in register_nspace on newly created daemons
* ensure orterun doesn't propagate any ess or pmix directives in its environment
* Cleanup a few valgrind issues and memory leaks
* Fix a race condition that prevented the client from completing notification registrations (missing thread shift)
* Ensure the shizo/alps component detects launch by mpirun
Cleanup the configury so we properly check for Singularity under the various typical use-cases
Bring the Singularity support online. We have to turn "off" the sm BTL as it segfaults from inside the container - root cause remains unclear. Also turned "off" the various OPAL shmem components in case they are involved and someone else tries to use them. Happily, the vader BTL works just fine!
