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.

bug 4987

These only work with accounting_storage/mysql, which cannot
be loaded directly in slurmctld any longer.

This would be triggered by bad logic in slurm, but we want the test
to be more resilient

Also includes some changes to gres.c and job_mgr.c needed to
support all gres types

test3.1 - verify that the user running the test is an Admin so
that reconfigure will work. If not, throw a warning and quit to
prevent the reconfigure macro from erroring out instead.

This is in anticipation of an upcoming change to the cgroup hierarchy
on a future CLE release.

Bug 3792.

Always zero on non-BG systems, so remove entirely.

Also start removing BG code, and take out err_cpus which is
always zero on non-BG.

Unused, but missed during prior clean up since it is
split across files.

Both are always one. (On non-BG.)

Always one (non-BG), so just change these to the increment operator.

SELECT_NODEDATA_SUBGRP_SIZE is always zero on non-BG, so all
calling paths into this can be removed.

Removing the CLUSTER_FLAG_BG block forces some code up a tabspot,
making this look a bit uglier than indended.

Also, remove the error_cpus values, as those only applied to BG.

NODE_STATE_ERROR is only valid on a BlueGene, so make this
a no-op for now.

As done previously, this can be removed as it always returns zero:
select_g_select_nodeinfo_get(node_ptr->select_nodeinfo,
                             SELECT_NODEDATA_SUBCNT,
                             NODE_STATE_ERROR,
                             &err_cpus);

Simplify the resulting code, and remove CLUSTER_FLAG_BG code as well.

No functional changes, but do cleanup some style in these
updated blocks while copying.

No changes yet.

Helps avoid pointer soup like &((*msg)->node_scaling).
No functional change.

Mention in RELEASE_NOTES in the appropriate sections.

Tidy up function declarations and formatting while here.

This is always 0 on non-select/bluegene. Remove other
BlueGene-specific output from this block while here.

This is all leading up to removal of the node_scaling concept
from Slurm's internals.
