The problem is that with high rate profiling, the cpu usage becomes a
binary field (see the output below). I would like to have a more accurate
value of the cpu usage. I'm thinking about writing another profiling
plugin that may be very useful in our environment, and probably also in
other environments where compute nodes are shared.

change is to ease future transition to IPv6 reducing the number of
places that use AF_INET.  AF_SLURM currently points to AF_INET though.

removed, so make sure we process correctly, sort it while we are at it.

Plus some cosmetic changes to a couple of tests

end up pointing to qos_ptr_2 erroneously.

clearing the pointer in the partition record.

Fix case where job would get the wrong cpu count when using --ntasks-per-core and --cpus-per-task together.

We are using a non-default AuthInfo configuration and based on
log-messages we see I believe this is not properly handled in certain
parts of the code.

Unfortunately the reservation's core_bitmap is a global bitmap and the nodes
in the system may have changed in terms of their node count or nodes have been
added or removed. Make best effort to rebuild the reservation's core_bitmap
on the limited information currently available. The specific cores might
change, but this logic at least leaves their count constant and uses the
same nodes
