As the reordering is an optional step, if any operation during the
reorder fails we can return the duplicata of the original communicator
associated with the topology information.

Per https://github.com/open-mpi/ompi/issues/3995, it should not be a
fatal error if the libnl checks fail. Instead, just fail the check
and let the upper layer decide what to do. In this case,
OPAL_CHECK_PACKAGE will mark this library as no good, and then
propagate that upward.
E.g., if libfoo fails the libnl check, and the user had specified
--with-libfoo, this will eventually cause configure to fail (because
the libnl check will fail with libfoo, which will cause
OPAL_CHECK_PACKAGE to fail with libfoo, which will ultimately cause
some upper-level logic to realize "a human asked for libfoo but we
could not provide it -- abort!").
However, if libfoo fails the libnl check and the user did *not*
specify --with-libfoo, then this will cause the upper layer to
silently skip libfoo (because the libnl check will fail libfoo, which
will cause OPAL_CHECK_PACKAGE to fail libfoo, but then the upper-level
logic will realize "oh, we can't use libfoo, but a human didn't ask
for it -- so just skip libfoo support.").

Make sure hostnames are null terminated, even when they were
too long to fit in the hostname buffer.

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).

Update opal configure logic to set disable_dlopen when disable_mca_dso is given. Fix typos in disable_dlopen when setting variables (incorrect inclusion of quotes)

This allows mtl_ofi_provider_include to work with layered providers as well.
e.g. --mca mtl_ofi_provider_include "providerX;ofi_rxm"

Add test suite for netlink and weighted reachable components. We
don't have a great way of running components through unit tests
today, so make them stand-alone tests that are run with mpirun
and such.

Amazon is going to use the reachable framework to fix some connection
bugs in the TCP BTL, so claim support ownership of the weighted and
netlink components.

Wire up the libnl utilities Jeff and Ralph added previously to
the netlink reachable component so that it actually does work.
The algorithm is a bit simplistic, but should work for our use
cases. If there's a route, assume the two interfaces can talk.
If there's no gateway, assume the two interfaces are in the
same subnet, and give preference to that connection. If there's
a gateway, assume there's a route, but the interfaces are not
in the same subnet.
