Don't do a recursive search (hence no need for *idx anymore).
Find the level depth, to hide cache-issues first.
Then iterate over that level to find the objects we want.

df_search_min_bound() would need to be fixed for hwloc 2.0,
but it's only used in opal_hwloc_base_find_min_bound_target_under_obj()
which isn't used anymore. So just remove all of them.

As @hjelmn and I discussed, this is a little hacky. However, it is the only solution that can be done solely from the OMPI side.

The mpool/memkind component was using a deprecated "partitions" API.
This commit refactors the memkind component to make use of the
supported public API.
The public API uses 3 parameters to specify a mpool "kind":
- a memkind type (which for now is just default or HBM)
- a memkind policy
- a memkind_bits (partly to specify pagesize)
The MCA parameters were changed to reflect these memkind
parameters.
Add a make check test for sanity checking of the memkind component.

Fixes issue #5069, which relates a BigMPI bug with the use of
MPI_Type_vectpor to construct very large datatypes (>2GB).

This commit fixes a segfault in btl-portals4 add_procs(). The segfault
occurs if add_procs() is called after a del_procs() call that reduces
the proc count to zero which would cause PT and NI resources to be
freed. This commit resolves the segfault by using a common
initiailization boolean and only freeing module resources in
finalize().

Have Open MPI's PMIx component to set PMIx's "show_load_errors" to do
the same thing that Open MPI's "show_load_errors" does.

Some of the show_help() messages that were added in 40afd525f8 were
really normal / expected behavior (e.g., if 2 peers connect in the TCP
BTL more-or-less simultaneously, one of them will drop the connection
-- no need to show_help() about this; it's expected behavior). Roll
back these messages to be opal_output_verbose() kinds of messages.

The strtoul function returns the pointer to the first non-digit character, which is a '.' in this case. Calling strtoul at that point will always yield a zero - you have to move past it to get the remaining number
Thanks to Greg Lee for the detailed analysis of the problem.

Simple MCA vars for ext1, ext2, and pmix3 components to reflect what
the underlying PMIx library version is. For example:
```
$ ompi_info --param pmix pmix3x --parsable --level 9 | grep

mca:pmix:pmix3x:param:pmix_pmix3x_library_version:value:PMIx library version 3.0.0 (embedded in Open MPI)

mca:pmix:pmix3x:param:pmix_pmix3x_library_version:level:4
mca:pmix:pmix3x:param:pmix_pmix3x_library_version:help:Version of the underlying PMIx library

sizeof(addrs[0].addr_inet)==16 (so that it can handle IPv6 addresses),
but the memory that we are copying from (my_ss->sin_addr) is only 4
