Fix for misleading job submit failure errors sent to users. Previous error
could indicate why specific nodes could not be used (e.g. too small memory)
when other nodes could be used, but were not for another reason.
bug 1537

Modify the command names per latest Cray documentation.
Add Cray API calls, which will replace the Cray command line
  interfaces when available. More work will be required for
  this conversion to the APIs.
Update documentation.

Correct the job array specification parser to accept brackets in job array
expression (e.g. "123_[4,7-9]").
This patch superseeds patch 8d811201
bug 1552

The logic fails if there are commas in the brackets:
slurmctld: job_str_signal: 3 invalid job id 1593_[2,5-6]
Updated patch in next commit

RequeueExit and RequeueExitHold configuration parameters modified to accept
numeric ranges. For example "RequeueExit=1,2,3,4" and "RequeueExit=1-4" are
equivalent.
bug 1549

If SchedulerParameters value of bf_min_age_reserve is configured, then
a newly submitted job can start immediately even if there is a higher
priority non-runnable job which has been waiting for less time than
bf_min_age_reserve.

If SchedulerParameters value of bf_min_age_reserve is configured, then
a newly submitted job can start immediately even if there is a higher
priority non-runnable job which has been waiting for less time than
bf_min_age_reserve.

Start job allocation using lowest numbered sockets for block task
distribution for consistency with cyclic distribution.
bug 1540

block is set up to it's original state.

Add the ability for a compute node to be allocated to multiple jobs, but
restricted to a single user. Added "--exclusive=user" option to salloc,
sbatch and srun commands. Added "owner" field to node record, visible using
the scontrol and sview commands. Added new partition configuration parameter
"ExclusiveUser=yes|no".  Add "Shared=user" job state information.

Bug 1533

Fix bug that can permit someone to kill job array belonging to another user.

Fix support for --mem=0 (all memory of a node) with select/cons_res plugin.
Previously the job would not have it's memory constrained, but it would not
make that memory unavailable to other jobs either.
bug 1526

This was previously added to v14.11

Added new SchedulerParameters value of bf_min_age_reserve. The backfill
scheduler will not reserve resources for pending jobs until they have
been pending for at least the specified number of seconds. This can be
valuable if jobs lack time limits or all time limits have the same value.

Increase maximum MaxArraySize configuration parameter value from 1,000,001
to 4,000,001.
bug 1535

Added LaunchParameters configuration parameter. Have srun command test
locally for the executable file if LaunchParameters=test_exec or the
environment variable SLURM_TEST_EXEC is set. Without this an invalid
command will generate one error message per task launched.

For job running under a debugger, if the exec of the task fails, then
cancel its I/O and abort immediately rather than waiting 60 seconds for
I/O timeout.
