Now that the daemon calls remote_spawn itself, there is no longer
a need for the "tree_spawn" command nor the associated command
processing code since the HNP is no longer sending a tree-spawn
message to the orted.
Thanks Ralph for the guidance !

When the node regex is too long to be sent on the command line,
retrieve it first from the parent, and then spawn the remote orted

This parameter can be used to set the node regex max length that can
be passed to the orted command line.
For testing purpose, it can be set to zero in order to force the node regex
being retrieved by orted from its parent.

They were incorrectly changed to subroutines in only `pmpi`
in 258d1aa160.
Strictly speaking, this change involves binary incompatibility.
But nobody used these subroutines and nobody will be affected because
these subroutines were useless (didn't return a calculated value).

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.

In both cases we were comparing with the wrong size, it should be either
the number of local processes or the number of nodes, and not the size

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.

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.
