We've discovered that our implementation of proctrack/cgroups includes
internal threads as well as the process pids so that "scontrol list pids"
shows them as well. The attached patch (courtesy of Matthieu Hautreux)
to 2.4.2 fixes this problem.

This patch adds logic to work around advanced reservations better.

Using the syscalls directly rather than calling bin/(u)mount via
system() avoids a few fork + exec calls, and provides better error
handling if something goes wrong.

Users of this functionality are also updated to use slurm_strerror in
order to provide a more informative error message.

The mount and umount syscalls are Linux-specific, but so are cgroups
so no portability is lost.

I would like to make two changes to this:

1) since the reservation name can easily exceed 9 characters, I would like the field to be however large it needs to be without truncating the name. I did this by looking at the names then setting the field size to that width.

2) The other headers are in capitals, so I changed

 ResName    State       StartTime             EndTime           Duration  Nodelist

to

RESV_NAME        STATE           START_TIME            END_TIME     DURATION  NODELIST
