1. Identifies nodes which are unavailable to a specific job,
adding a call to filter_by_node_owner() in select_nodes()
 where the node list is generated.
2. Removes the "unavail_node_str" argument to select_nodes()
as it is no longer useful. This string originally was originally
generated once at the start of the job scheduling logic for all jobs,
but since each job can have a different set of
 unavailable nodes (dedicated to user, group, etc.)
so the same string for all jobs can be misleading.

Prevent from wrongly returning, ESLURM_NODE_NOT_AVAIL from _pick_best_nodes when some jobs are using "--exclusive=user"

Bug 4932.

Improve performance of 'squeue -u' when PrivateData=jobs is
enabled by moving the UID filter code ahead of the more expensive
PrivateData=job checks.

If scaling_available_frequencies file is not available, then derive
values from scaling_min_freq and scaling_max_freq values. If
cpuinfo_cur_freq file is not available then try to use scaling_cur_freq.

This should never happen, but it does harden the code

This is a refinement to commit 95ab36b3

bug 4968

Related to buffer create/destroy operation being supported with
both #BB and #DW prefix.

These are jobs that only create or destroy persistent burst buffers,
so some job data structure fields required by NHC are not available
and can cause an invalid memory reference

over any other nodes.
