Use the PVAR ctx to save the SPC index, so that no lookup nor
restriction on the SPC vars position is imposed.
Make sure the PVAR are always registered.

When using an empty fileview, a division by zero bug can occur in ompio. Not entirely sure why the problem did not show up previously, but some recent changes trigger that bug in one of our tests.
This pr is part of a fix applied in commit f6b3a0a
Fixes Issue #6703

Atomic lock must progress local worker while obtaining the remote lock,
otherwise an active message which actually releases the lock might not

SLURM 19 discontinued the use of --cpu_bind (and changed it to
--cpu-bind). There's no easy way to test at run time which one is
accepted, so set the environment variable SLURM_CPU_BIND to "none",
which should do the same thing as the srun CLI parameter.

In OMPI 2.1.2, buildrpm.sh could work with a value of rpmtopdir that was
set in the environment. In newer versions this is no longer true,
causing such values to be ignored. This patch adds a new argument to
buildrpm.sh, -R, which allows the user to specify where to build the
RPMs.

The new routine transfers the data asynchronously from the source PE to all
PEs in the OpenSHMEM job. The routine returns immediately. The source and
target buffers are reusable only after the completion of the routine.
After the data is transferred to the target buffers, the counter object
is updated atomically. The counter object can be read either using atomic
operations such as shmem_atomic_fetch or can use point-to-point synchronization
routines such as shmem_wait_until and shmem_test.

make-authors.pl checks that .git exists and is a directory before
getting the git log - but when a repo is checked out as a submodule of a
larger repository, .git is not a directory, it's just a text file. This
can cause make-authors.pl to terminate inappropriately.

There are a couple MPI_Alltoallv calls in ad_gpfs_aggrs.c where the
send/recv data comes from places like req[r].lens, and the send
buffer and send displacements for example were being calculated as
sbuf = pick one of the reqs: req[bottom].lens
sdisps[r] = req[r].lens - req[bottom].lens
which might be okay if the .lens was data inside of req[] so they'd
all be close to each other. But each .lens field is just a pointer
that's malloced, so those addresses can be all over the place, so the
integer-sized sdisps[] isn't safe.
I changed it to have a new extra array sbuf and rbuf for those two
Alltoallv calls, and copied the data into the sbuf from the same
locations it used to be setting up the sdisps[] at, and after the
Alltoallv I copy the data out of the new rbuf into the same
locations it used to be setting up the rdisps[] at.
For what it's worth I was able to get this to fail -np 2 on a GPFS
filesystem with hints romio_cb_write enable. I didn't whittle the
test down to something small, but it was failing in an
MPI_File_write_all call.
