If a job with running steps is resized, that will result in the job's
core_bitmap size changing, but not that of the step, resulting in an
error message. This adds a job resized flag and prints a more meaningful
message when appropriate.

change to bit_ffs/bit_fls rather than full scan, improves performance

Previous logic could abort in some cases

The last merge from v18.08 (c6f696db) included changes that
are incompatible with cgroup configuration read function changes
that were made in master.

sinfo output in this test is grouping all nodes together in one
output line (e.g. "nid[000001-000099'), while the data used to
have one node per line. Adding the "-N" option to the test returns
the output to one node per line, as required for the test to work.

Bug 5750

when the node_bitmap scan was changed from checking all nodes
to just the nodes within the range set, the node_ptr became
wrong, resulting in bad job counts on nodes and nodes marked
as allocated when there were no jobs active (bug only in master).

No change in logic

Move reused GRES parsing logic to a shared function

This shouldn't happen in practice.
bug 5749

Test1.113 was sometimes failing due to timing issues related to
the Cray Node Health Check running. Add small sleep to (mostly)
eliminate the problem.

The option was previously ignored with the cons_res plugin plus
topology/tree. With cons_tres, handle the option by ignoring the
topology and using the default node selection logic.

add logic to provide optimized resource allocation with respect
to topology/tree configuration. Mostly working
Fix max-node enforcement

They were being referenced prior to initialization

This better handles job submit failures and reduces the time spend
waiting for output files by overlapping the wait for all files.

without this the total GRES counter can keep getting incremented,
the _get_job_cnt() calculation can overflow and extra GRES be
allocated to the job

This reverts debugging accidentally committed in 48ec9695

There are a few anomalies with respect to front-end mode, which
test test changes address

Surrounding with spaces ensures the closing paren isn't accidentally

Bug 5463.

Now slurmctld will fatal if the two incompatible memory enforcement mechanisms
are configured at the same time (JobAcctGather + task/cgroup). Also, a new info
message in slurmctld startup will indicate if there are not any configured
mechanism.

Bug 5479

MemLimitEnforce and setting NoOverMemoryKill kills the job, or the job step
respectivelly if the memory is exceeded at some point based on JobAcctGather
plugin information, in a JobAcctGatherFreq frequency basis.

Both are incompatible with task/cgroup memory enforcement. The defaults have
been changed to not setting any mechanism, and info/fatal messages added
accordingly to give useful info to the admin. Moreover NoOverMemoryKill has
been deprecated in favor of OverMemoryKill and a fix on the detection of job
memory confinement has been included.
