We need to return a persistent request.
`ompi_request_empty` is not a persistent request.

This was done after discussions with core developers about any
potential ABI breakage for any of the libs the user directly
links against. Also compaitiblity tests were done using the
ibm test suite and building with v3.1.x and running with v4.0.x

Since openib is on its long, slow way out the door, don't let it
complain about not being able to find any NICs at run time.

As agreed on #4574, where removed in past release branches
to avoid perfomance impacts in the default values for

This commit fixes a bug when using the UCT btl with the UCX memory
hooks disabled. We were misssing a call to
opal_mem_hooks_unregister_release to remove the btl memory hook
callback.

If someone specifies --with-verbs-usnic, actually do a configury check
to ensure that it will compile (vs. assuming that it will compile if
someone asks for it).

This commit removes some code that protected the odls/alps component
from closing alps file descriptors. For some unknown reason leaving
these file descriptors open causes can cause an orted to hang when
launching apps.

Since progress entries array is globally allocated, it is susceptible
to race conditions when using multi-threaded applications. Allocating it
on the stack resolves any potential races as it is thread local by default.

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.
