'-' is not an alpha character nor a digit, but it is a valid hostname
character and should be handled as an alpha character, otherwise, nodes
such as node-001 do not get "compressed" in the regex.

It is possible to have parts of an in-use registered region be passed
to munmap or madvise. This does not necessarily mean the user has made
an error but does mean the entire region should be invalidated. This
commit checks that the munmap or madvise base matches the beginning of
the cached region. If it does and the region is in-use then we print
an error. There will certainly be false-negatives where a user
unmaps something that really is in-use but that is preferrable to a
false-positive.

This commit updates the configure code for Open MPI to check for C11
support. The features requested are: atomics and thread local
storage.

There were multiple paths that could lead to a fast box
allocation. One of them made little sense (in-place send) so it has
been removed to allow a rework of the fast-box send function. This
should fix a number of issues with hanging/crashing when using the
vader btl.

OMPI_FORTRAN_USEMPIF08_MOD macro was removed in open-mpi/ompi@791bcee6c0
so this macro is now manually expanded to mpi/fortran/use-mpi-f08/mod

set the key of all mpool_tree_item objects, so they can be retrieved
in mpool_base_free and then returned back to the
mca_mpool_base_tree_item_free_list free list.

Fix ability to build examples from 32-bit builds. Remove the implicit
rule usage, so that we know what flags are being used. Make the override
of the FLAGS variables additive so that we don't wipe out FLAGS variables
set in the environment.

This commit removes eax and edx from the clobber list. Older versions
of gcc handled these ok but gcc 7 does not. They are not required as
eax and edx are specified in output constraints.

ompio has the unique problem, that mca parameters set in the io/ompio component
have to be accessible from other frameworks as well. This is mostly done to avoid
a replication in the parameter names and to reduce the number of mca parameters that
and end-user has to worry about.
This commit introduces a generic function to retrieve ompio mca parameters, the function pointer
is stored on the file handle. It replaces two functions that used the same concept already for
one parameter each.

Only selectable when specifically requested via "-mca odls pspawn"
Note that there are several concerns:
* we aren't getting SIGCHLD calls when the procs terminate
* we aren't seeing the IO pipes close on termination, though
we are getting output forwarded to mpirun
* I haven't found a way to bind the child process prior to exec.
If we want to use this method, we probably need someone to
implement a cgroup component for the orte/rtc framework

This commit adds support for fetch-and-op atomics. This is needed
because and and or are irreversible operations so there needs to be a
way to get the old value atomically. These are also the only semantics
supported by C11 (there is not atomic_op_fetch, just
atomic_fetch_op). The old op-and-fetch atomics have been defined in
terms of fetch-and-op.

This commit renames the arithmetic atomic operations in opal to
indicate that they return the new value not the old value. This naming
differentiates these routines from new functions that return the old
