This commit fixes an issue when a registration is created for a large
region and then invalidated while part of it is in use.

This fixes a regression in sockets provider which could return -EINTR value
from fi_cq_read() due to a syscall being interrupted. The error value is
currently interpreted as fatal condition. Relax the rule so that we can retry
fi_cq_read() operation.

As documented in #4563 and #3697, there is an issue on ARM and
POWER platforms when the atomic fifo assembly isn't inlined,
which manifests as a hang. Document the issue and the
work-around until a proper fix is committed.

If we detect that someone has given us an incorrect node name, provide a helpful message telling them as it is almost certainly a typo.

This commit moves the backing files to /dev/shm to avoid limitations
that may be set on /tmp. The files are registered with pmix to ensure
they are cleaned up after an erroneous exit.

(cherry picked from commit 48101278160672317ade352365592f56ef3b8977)
If available, have apps use registration capability to cleanup their session directories. Setup capability for vader to register its shared memory file location - let someone familiar with that code do so.
Final cleanup to track uid/gid, update the opal/pmix API to pass flags for ignore and leave top directory alone

Somehow, the code for passing a daemon's parent was accidentally removed, thus breaking the tree-spawn callback sequence and causing all daemons to phone directly home. Note that this is noticeably slower than no-tree-spawn for small clusters where directly ssh launch of the child daemons from the HNP doesn't overload the available file descriptors.

'-' 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.

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.
