By default all devices are allowed and GRES, that are associated with a
device file, that are not requested are restricted.

Leaving the ability to read in the file as a contribution is under
review that extends the cgroup_allowed_devices_file.

fa38c431 was the commit this was added in where s_p_get_float
wasn't added until e1d2a0c1.

The conditional for handling --overcommit was not sufficient to prevent

And set it in launch_prolog().

Previous logic would re-use altered node and core bitmaps,
which would tend to fail.
Change some data types for consistency

Cores on additional sockets may be used, but we want to insure some
cores on the identify sockets are included in the job allocation

In cases when you have a range first and then a single afterwards:

nid00[446-447],nid00392

It only worked correctly if it were reversed like so:

nid00392,nid00[446-447]
