This commit removes some code that protected the odls/alps component
from closing alps file descriptors. For some unknown reason leaving
these file descriptors open causes can cause an orted to hang when
launching apps.

In some scenarios, we can have a daemon sharing the node with mpirun. In
those cases, we need to avoid race conditions in cleanup

Per suggestion by @bangerth, allow mpirun to execute as root if two
envars are set to specific values
Per conversation with @jsquyres, name the envars OMPI_ALLOW_RUN_AS_ROOT
and OMPI_ALLOW_RUN_AS_ROOT_CONFIRM

Since version hwloc 2.0.0 has a new organization of NUMA nodes on the
topology tree. This commit adds the detection of local NUMA object for
hwloc => 2.0.0, which fixes the procs bindings policy for rmaps mindist
component.

Both orted and mpirun use threads to speed up local process spawing.
In order to avoid data corruption when calling the opal_output
interface we need to ensure that opal_using_threads is set to true.

Things got a little out of whack and we weren't actually processing the map-by modifiers, plus an error crept into the display of the binding report. So clean those up.

(cherry picked from commit ea0d70bc9396def61545e2ce492a55c4c3aa7772)
Do not have child jobs inherit launch directives unless requested to do so. This affects the map-by, rank-by, bind-to, npernode, pernode, npersocket, persocket, and cpus-per-rank directives. Values provided in the spawn call always take precedence - if a particular value isn't specified, then the ORTE defaults will be used if inheritance is not requested, and the values specified by MCA param will be used if inheritance is set.
Always inherit oversubscribe for now as otherwise MTT will break

Since the new binding option is tied to the --cpu-list orterun CLI
option, make the --bind-to option reflect the same name (vs. the
--cpu-set CLI option, which is entirely different). For example:
mpirun --bind-to cpu-list:ordered ...
Note that "--bind-to cpulist:ordered" is accepted as a synonym,
because people will be lazy.
Also add some minor updates to the orterun.1in man page for
clarification.

A race condition exists based on whether or not the userdata object attached to a hwloc_obj_t has been initialized. These objects are setup whenever we scan for resources under that location. You therefore must not set a variable to the pointer to the userdata object and then call a function that will initialize the data in it - you need to set the variable after the function call, and protect against a NULL pointer

The PMIx support for "instant on" remains experimental, so disable it by default. Provide an MCA param and corresponding command line option to enable it at runtime.

This is a minor abstraction break in naming, but hopefully acceptable for now. I will update the contents of the program a little later. This resolves the immediate issue of naming conflict with the PRRTE binary.

This still leaves two unresolved warnings:
base/rmaps_base_binding.c:577:22: warning: variable ‘clvm’ set but not used [-Wunused-but-set-variable]
unsigned clvl=0, clvm=0;
^~~~
base/rmaps_base_binding.c:576:27: warning: variable ‘hwm’ set but not used [-Wunused-but-set-variable]
hwloc_obj_type_t hwb, hwm;
^~~
The problem is that these values are used in the OPAL_HWLOC_MAKE_OBJ_CACHE macro to form a variable name. Thus, the compiler doesn't recognize the values as being "used". I'm not entirely sure how to resolve it cleanly.

Don't bother doing a lookup upwards or downwards for the target object type.
Just use the target depth, iterate over the level until we find the min_bound
object that intersects the locale cpuset.

This fixes a problem reported by @bgoglin where rank-by was incorrectly generating values when ranking by a type of object (e.g., socket). It also corrects the handling of the pernode, npernode, and npersocket options - these should only set the #procs and the default mapping pattern. They specifically should not prohibit the user from requesting a different mapping.
Thus, the following should be valid:
mpirun -npernode 2 --map-by socket ...
should put 2 procs on each node, mapping them by-socket on each node.
