Note there was a bug in the configuration parsing logic to get
the partition's DefMemPerGPU (it was stored in the field for
DefCpuPerGPU).

This avoid queueing jobs that can not run due to a gres limit.

This was missed when committing before.

This will be needed in a future commit.

Doesn't do anything yet, just pack and print.

Just a name change.

No real code change.

This only adds the nuts and bolts, it doesn't do anything outside

Precursor to changes being added in next commits

Previously needed to lookup the ID to get the name. This should
be better.

Translate any GRES Type string to a numeric value and replace a
bunch of strcmp() operations with numeric comparison for improved
speed. This is important because cons_tres will be making heavier
use of GRES data.
