gres_node_config_load() requires gres_list to work properly after
fully merge slurm.conf with gres.conf logic added in 4d7df8b0.

Bug 7490

If not enforcing QOS, it's possible to submit a job without a qos. If
submitting such a job to multiple partitions where at least one has a
qos, slurmctld would abort in a development build. A non-development
build didn't segfault only because _find_qos_part doesn't dereference
the NULL pointer. Prevent the abort.

Now it will work with multiple GPU types. This currently affects tests
like a subset of the test39.* series and test1.62.

Bug 7884.

If there are less than 2 sockets per node, only the first part of the
test needs to be skipped. So the second half of the test was changed
to still run as long as 2+ GPUs are configured.

Also add headers to sub-tests while here.

Ensure gres_plugin_node_config_load() is called with a gres_list.

Otherwise we would be incorrectly reusing the previous to the
reconfiguration slurm.conf GRES value.

Continuation of previous commit.

Bug 7884.

Ensure that the stepd has slurm.conf GRES data. If the slurm.conf
input argument is NULL for gres_plugin_node_config_load(), then
gres_devices will end up being NULL, causing all GRES binding to not
work.

Bug 7884.

Previous logic would only call s_p_hashtbl_create() to create the hashtable
when the file acct_gather.conf could be successfully stat()'d. This lead to
a subsequent attempt to pack the non-created hashtable into a buffer which
triggered the abort.

This makes it so the hashtable is uncondtionally created no matter if the
file is missing.

Bug 7893.

gethostbyaddr() can potentially return a fully-qualified domain name,
which breaks backwards compatibility with the shortname AllocNodes
expected pre 19.05.

Fortunately the extra arguments were provided at the end, and thus ignored on
most common platforms.

Bug 6605

Instead of giving user as "nobody", give user numeric id. The RPC stats
last the lifetime of the slurmctld process and thus may have users that
have been removed.

There is no performance benefit from caching users in sdiag as it will
only lookup each user once. Caching adds qsort insert cost to every
user for no benefit. Swapped from non-cached call to direct user lookup.
