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.

file_delete triggers underneath the hood the full component selection
logic, since we do not have a file handle, just a file name.
As part of the selection logic, we have to however initiate the
framework-open of the fs component in case of ompio, since ompio
will call the delete function of the selected fs componentn, which
is based on the file system where the file is located.
This was not handled correctly so far. The problem however only
shows up if the first I/O operatin to be executed is a file_delete,
other wise the file_open will lead to the correct opening and initialization
of the fs framework. This commit ensures that we do the right thing
even if file_delete is the first file I/O operation in the application.

If an application opens a file for reading from multiple processes
using MPI_COMM_SELF (or another communicator that has distinct
process groups but the same comm-id, as can happen as the result
of comm_split), the naming chosen for the lockedfile or the mmapped
file used by the sharedfp/sm component would collide. This patch
ensures that the filename is different by integrating the process id
of rank 0 for each sub-communicator.
This fixes one aspect of the problem reported in github issue 5593

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.

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.
