Move the prefix area from the head to the body in relevant size
computations. This fixes a problem in high traffic situations where
usNIC may have sent from unregistered memory.

New MCA param: btl_usnic_max_resends_per_iteration. This is the max
number of resends we'll do in a single pass through usNIC component
progress. This prevents progress from getting stuck in an endless
loop of retransmissions (i.e., if more retransmissions are triggered
during the sending of retransmissions). Specifically: we need to
leave the resend loop to allow receives to happen (which may ACK
messages we have sent previously, and therefore cause pending resends
to be moot).

Significantly increase the default retrans timeout. If the
retrans timeout is too soon, we can end up in a retransmission storm
where the logic will continually re-transmit the same frames during a
single run through the usNIC progress function (because the timer for
a single frame expires before we have run through re-transmitting all
the frames pending re-transmission).

New MCA parameter: btl_usnic_ack_iteration_delay. Set this to the
number of times through the usNIC component progress function before
sending a standalone ACK (vs. piggy-backing the ACK on any other send
going to the target peer).
Use "ticks" language to clarify that we're really counting the number
of times through the usNIC component DATA_CHANNEL completion check (to
check for incoming messages) -- it has no relation to wall clock time
whatsoever.
Also slightly change the channel-checking scheme in usNIC component
progress: only check the PRIORITY channel once (vs. checking it once,
not finding anything, and then falling through the progress_2() where we
check PRIORITY again and then check the DATA channel).
As before, if our "progress" libevent fires, increment the tick
counter enough to guarantee that all endpoints that need an ACK will
get triggered to send standalone ACKs the next time through progress,
if necessary.

* The user can set `-mca odls_base_sigkill_timeout 30` to have ORTE wait
30 seconds before sending SIGTERM then another 30 seconds before sending
SIGKILL to remaining processes. This usually happens on an abnormal
termination. Sometimes the user wants to delay the cleanup to give the
system time to write out corefile or run other diagnostics.
* The problem is that child processes may be completing while ORTE is
in this loop. The SIGCHLD will interrupt the `sleep` system call.
Without the loop the sleep could effectively be ignored in this case.
- Sleep returns the amount of time remaining to sleep. If it was
interrupted by a signal then it is a positive number less than or
equal to the parameter passed to it. If it slept the whole time
then it returns 0.

INTERNAL: STL-59403
The OFI (libfabric) MTL does not respect the maximum message size
parameter that OFI provides in the fi_info data.
This patch adds this missing max_msg_size field to the mca_ofi_module_t
structure and adds a length check to the low-level send routines.

Trying out to run processes via mpirun in Podman containers has shown
that the CMA btl_vader_single_copy_mechanism does not work when user
namespaces are involved.
Creating containers with Podman requires at least user namespaces to be
able to do unprivileged mounts in a container
Even if running the container with user namespace user ID mappings which
result in the same user ID on the inside and outside of all involved
containers, the check in the kernel to allow ptrace (and thus
process_vm_{read,write}v()), fails if the same IDs are not in the same
user namespace.
One workaround is to specify '--mca btl_vader_single_copy_mechanism none'
and this commit adds code to automatically skip CMA if user namespaces
are detected and fall back to MCA_BTL_VADER_EMUL.

This commit fixes an compilation error when configured
with `--enable-timing`.
Procedures in the function `orte_ess_base_app_setup`
in `orte/mca/ess/base/ess_base_std_app.c` are moved
to `orte/mca/ess/pmi/ess_pmi_module.c`
and `orte/mca/ess/singleton/ess_singleton_module.c`
in the recent commit 57f6b94fa5.
In `ess_pmi_module.c`, the first argument of the
`OPAL_TIMING_ENV_NEXT` macro should have been adapted
to the destination function but was not.
In `ess_singleton_module.c`, `OPAL_TIMING_ENV_INIT`
was not used in the destination function originally.
So `OPAL_TIMING_ENV_NEXT` cannot be used in the function.

* Fix#6618
- See comments on Issue #6618 for finer details.
* The `plm/rsh` component uses the highest priority `routed` component
to construct the launch tree. The remote orted's will activate all
available `routed` components when updating routes. This allows the
opportunity for the parent vpid on the remote `orted` to not match
that which was expected in the tree launch. The result is that the
remote orted tries to contact their parent with the wrong contact
information and orted wireup will fail.
* This fix forces the orteds to use the same `routed` component as
the HNP used when contructing the tree, if tree launch is enabled.

open-mpi/ompi@0fe756d416 Introduced
a bug in coll/hcoll component. The ompi_requests allocated by
libhcoll would be treated as coll_base_nbc_request during
ompi_coll_base_retain_<> call. Afterwards this would lead to a
segv in the request cleanup.
Fix: since libhcoll interface does not distinguish between the
blocling/non-blocking requests use coll_base_nbc_request all the
time and initialize it properly in
coll/hcoll/get_coll_handle(). It is still within 2 cache lines.
