ip_mroute: Fix a lock leak in X_ip_mforward()
If a FIB does not have a router configured, X_ip_mforward() would leak a
lock. Plug the leak.
The IPv6 counterpart did not have such a check. It wouldn't send an
upcall to a non-existent router anyway due to the router_ver check, but
we should verify that a router is present anyway.
Add regression test cases to exercise these code paths.

du: Complete libxo transition
* Use xo_warn() / xo_err() instead of warn() / err().
* Add a test case for the POSIX-mandated stdout error check.
* While here, don't assume the size of off_t, address some style issues,
and broaden the use of bool instead of int.
* Reorder SEE ALSO section.

sysutils/mpifileutils: New port: MPI parallel file utilities for high scalability on large filesystems
FileUtils provides a library (libmfu) and a suite of MPI-parallel file
utilities such as dcp (parallel copy), dcmp (compare), ddup (duplicate
finder), dfind, dtar/dbz2, dchmod, and more. Designed for high
scalability on large filesystems.

devel/libcircle: New port: API to distribute parallel workloads across MPI ranks
libcircle provides an API for distributing embarrassingly parallel
workloads across MPI ranks using a distributed work queue.
Applications register callbacks to create and process work items, while
the library handles load balancing, termination detection, and optional
global reductions. It is commonly used on large HPC filesystems to
traverse directory trees and perform file operations in parallel on
hundreds or thousands of processes.

devel/lwgrp: New port: Light-weight group library for MPI
The Light-weight Group library provides data structures and collectives to
create/destroy ordered process groups efficiently in MPI codes — useful when
frequent, transient groups make communicator creation too costly.

linuxkpi: Fix an off-by-one error in the kfifo implementation
"total" is the number of slots in the array, so wraparound needs to be
done when "first" or "last" is greater than or equal to the number of
slots.
Note that no consumers of the code are currently connected to the kernel
build.
