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

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.

* The `MPIR_PROCDESC` structure needs to be visible even in optimized
builds so that debuggers can attach to `mpirun` and properly read the
`MPIR_proctable`.
* In the v2.0.x and v2.x series this structure resided in the `orterun`
directory and included the `CFLAGS` fix included here. This code
moved in the v3.x series and the `CFLAGS` did not move causing this
issue.
- Instead of applying the debug `CFLAGS` globally to libopen-rte,
only apply them to the `orted_submit.c` compile which contains the
MPIR symbols.

The current code path for PMIx_Resolve_peers and PMIx_Resolve_nodes executes a threadshift in the preg components themselves. This is done to ensure thread safety when called from the user level. However, it causes thread-stall when someone attempts to call the regex functions from _inside_ the PMIx code base should the call occur from within an event.
Accordingly, move the threadshift to the client-level functions and make the preg components just execute their algorithms. Create a new pnet/test component to verify that the prge code can be safely accessed - set that component to be selected only when the user directly specifies it. The new component will be used to validate various logical extensions during development, and can then be discarded.

(cherry picked from commit 456ac7f7af3d9ba09888e3c899eb001daaa24aef)
This is a point-in-time update that includes support for several new PMIx features, mostly focused on debuggers and "instant on":
* initial prototype support for PMIx-based debuggers. For the moment, this is restricted to using the DVM. Supports direct launch of apps under debugger control, and indirect launch using prun as the intermediate launcher. Includes ability for debuggers to control the environment of both the launcher and the spawned app procs. Work continues on completing support for indirect launch
* IO forwarding for tools. Output of apps launched under tool control is directed to the tool and output there - includes support for XML formatting and output to files. Stdin can be forwarded from the tool to apps, but this hasn't been implemented in ORTE yet.
* Fabric integration for "instant on". Enable collection of network "blobs" to be delivered to network libraries on compute nodes prior to local proc spawn. Infrastructure is in place - implementation will come later.
* Harvesting and forwarding of envars. Enable network plugins to harvest envars and include them in the launch msg for setting the environment prior to local proc spawn. Currently, only OmniPath is supported. PMIx MCA params control which envars are included, and also allows envars to be excluded.

Since we now support the dynamic addition of hosts to the orte_node_pool, there is no longer any reason to require advanced specification of all possible nodes. Instead, use a precedence method to initially allocate only those hosts that were specified in the cmd line:
* rankfile, if given, as that will specify the nodes
* -host, aggregated across all app_contexts
* -hostfile, aggregated across all app_contexts
* default hostfile
* assign local node
Fix slots_inuse accounting so that the nodes are correctly reset upon error termination - e.g., when oversubscribed without permission.
Ensure we accurately track the user's specified desires for oversubscribe and no-use-local when dynamically spawning jobs.
