Enabling this alters the scheduling sorting algorithm so that hetjob
components belonging to the same hetjob are attempted to be scheduled
consecutively (not interleaved with other jobs or hetjob components).

Regression introduced in ccafaf7b.

Replace the (was always set to true) check_current_dir argument to
search_path() with check_cwd_last boolean to indicate if cwd should be
evaluated first (needed by sbatch) or last (salloc/srun).

Bug 6271.

Kill running/pending job is allocated GRES and that GRES has a "File"
    configuration, and the GRES count changes.
Also generally better handle changes in GRES count (avoid some bugs
    in GRES data structures).

Bug 6283

SizesByAccount and SizesByAccountAndWckey now defaults to display the
root account totals, or the exact requested Account=. To query like the old
behavior a new option 'AcctAsParent' has been added which will still shown
the subaccounts of the requested accounts in Account=.

This patch also simplifies the code using bit_cnt instead of
_bitstr_bits().  This isn't really necessary, but does look cleaner.

Bug 6093

New X11 forwarding code will only support forwarding back to
salloc or an allocating srun command.

Using this option within sbatch was always hit-or-miss. If the
user submitting was disconnected from the alloc host for any
reason their xauth credentials would likely fail even if they
managed to get assigned the same local TCP port for forwarding.

Bug 3647.

In some systems there can be multiple user accounts for uid 0, therefore
the check for literal user name "root" might be insufficient.

Bug 6184

This pam module is tailored towards running in the context of remote ssh
logins. When running in a different context like a local sudo call then
the module could be influenced by e.g. passing environment variables
like SLURM_CONF.

By limiting the module to only perform its actions when running in the
sshd context by default this situation can be avoided. An additional pam
module argument service=<service> allows an Administrator to control
this behavior, if different behavior is explicitly desired.

Bug 6184

Only print a warning for 18.08. If a user has SLURM_MEM_PER_CPU or
SLURM_MEM_PER_NODE environment variables set for some reason this
situation could be happening by accident, and we don't want to prevent
the srun command from launching steps at this point.

Bug 5648.

The Linux kernel default hard limit of 4096 for the number of file
descriptors is quite small. Debian/Ubuntu have for a long time
overridden this, increasing it to 1M. Recently systemd also bumped the
default to 512k.

Here the limits are increased as follows:

- slurmd: 128k; some workloads like Hadoop/Spark need a lot of fd's,
  and recommend that the limit is increased to at least 64k.

- slurmctld: 64k; per the Slurm high throughput and big system guides
  which recommend a file-max of at least 32k.

- slurmdbd: 64k, matching slurmctld, though slurmdbd shouldn't need
  that many fd's, bumping the limit shouldn't hurt either.
