We know that hwloc:external will be configured first (because of its
priority). Take advantage of that here in hwloc201 by having it
refuse to configure / politely fail if hwloc:external succeeded.
Also print out some additional lines in configure output indicating
what is going on (i.e., hwloc:external succeeded, so this component
will be skipped, or hwloc:external failed, so this component will be
used).

(cherry picked from commit 4e5f432786d1ab99304e40dadec40ac45e93e76f)
If OMPI is configured with `--with-hwloc=external` or `--with-hwloc=DIR`
and gfortran is used, I see a lot of warnings when compiling files
under the `ompi/mpi/fortran` directory.
```
f951: Warning: Nonexistent include directory
'BUILD_DIR/opal/mca/hwloc/external/hwloc/include' [-Wmissing-include-dirs]
```
There is no such `include` directory in the source tree and `configure`-
created tree. I think these lines in the `configure.m4` file are wrongly
copied from that for the embedded `hwlocXXX` component in the past.
The `-Wmissing-include-dirs` option is enabled in gfortran by default
but it is not enabled by default (or even with `-Wall`) in gcc and g++.

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.

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.

Be a little more deliberate about convering OMPI's --with-cuda CLI
value to hwloc's --enable-cuda configure option.
Also, unconditionally disable hwloc NVML support (because Open MPI is
not currently using it).

Adopting can fail if the server-side hole isn't available on the client.
We can fallback to other ways to load the topology.

Commit fec519a793a2afcfd1ebcb3fa7c151bd30893835 broke the ability to
run autogen.pl in a distribution tarball. This commit restores that
ability by also distributing opal/mca/hwloc/autogen.options in the
tarball.

hwloc v1.5 does not support HWLOC_OBJ_OSDEV_COPROC
nor hwloc_topology_dup(), so for this version :
- do not search for coprocessors
- do not try hwloc_topology_dup(), note this is not
used anywhere in the code base
Thanks Jeff for helping with the wording

Per a prior commit, the presence of "hwloc.h" can cause ambiguity when
using --with-hwloc=external (i.e., whether to include
opal/mca/hwloc/hwloc.h or whether to include the system-installed
hwloc.h).
This commit:
1. Renames opal/mca/hwloc/hwloc.h to hwloc-internal.h.
2. Adds opal/mca/hwloc/autogen.options to tell autogen.pl to expect to
find hwloc-internal.h (instead of hwloc.h) in opal/mca/hwloc.
3. s@opal/mca/hwloc/hwloc.h@opal/mca/hwloc/hwloc-internal.h@g in the
rest of the code base.

Allow someone to specify the "pe=N" modifier to a mapping policy when N=1. This equates to just "bind-to core", but helps people who use a script to set the PE policy. Fix a bug where setting the binding policy left a lingering "if-supported" flag that shouldn't be there.
