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

Thanks to Stefan Teleman for identifying this issue and providing a
proof-of-concept patch. We ended up revamping the detection of
128-bit atomics to reduce duplicated code and be a slightly simpler --
albiet perhaps a bit more verbose -- approach:
- Remove the --enable-cross-* options; they were confusing and
unnecessary.
- Always try to compile / link the compiler-intrinsic 128-bit atomic
functions.
- Strengthen the C tests we use to be more robust.
- Use m4 to avoid duplicating the C tests multiple times in the .m4
source.
- If not cross-compiling, try to run a short test and ensure that they
actually work (as of Aug 2018, there's at least one platform where
they don't: clang 6 on ARM64). If cross-compiling, just assume that
they work.
- Add more comments about what is going on with all the tests; it's
tricky stuff. Our Future Selves will thank us.

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.

The aggregation code in osc/rdma is currently broken and will likely
not be reused. This commit cleans it out.

When an application is not using multiple threads to call into MPI, we can
safely ask for FI_THREAD_DOMAIN setting from the provider as it should
translate to the least amount of locking in provider.
Conversely, for applications using THREAD_MULTIPLE, explicitly ask for
FI_THREAD_SAFE to prevent race conditions.

gcc complains about ret possibly being used uninitialized. That will
never happen but we should still quiet the warning. This commit sets
ret to a valid value.

the sharedfp component has to be selected and opened before
we set the default file view during file_open. Otherwise
there is a sperious error message from the sharefp_file_seek
operation that is called during the file_set_view.

bugfix: major: openib send credits returned correctly after a fault for pending frags to dead processes; also tweak the default IB retry timeouts tomake this happen faster
Make it compile in non-debug builds
Mark the IB endpoint as failed when invoking an error; this resolves UDCM connection deadlocks
Changing the default IB retry timeouts is not a good idea.
We'll need to find another way to speedup credit recovery in failure cases.
Remove ULFM specific cases

The important part of this fix is a couple places 5 was hard-coded that needed to be
strlen(OPAL_INFO_SAVE_PREFIX).
But also this contains a fix for a gcc 7.3.0 compiler warning about snprintf(). There
was an "if" statement making sure all the arguments had appropriate strlen(), but gcc
still complained about the following snprintf() because the size of the struct element
is iterator->ie_key[OPAL_MAX_INFO_KEY + 1].
