As part of the setup activity prior to invoking the CCM prologue on Cray native
Slurm systems, the job prolog_running value is incremented and the job_state is
OR'd with JOB_CONFIGURING.  After the CCM prologue completes, these field
changes are removed.  That setup activity allows the CCM prologue to complete
before the job launch continues.

If the slurmctld is shutdown or killed while a CCM prologue is executing, those
two job field changes can't be removed since slurmctld is no longer there.
Clearing those field values is now handled during job recovery within the
select/cray plugin select_p_job_init() procedure.  If a job being recovered came
from a CCM defined partition and if either of those two field values are still
set as above, then the CCM prologue is run again.

The CCM prologue handles being called more than once.  The above field changes
are then removed after this rerun CCM prologue completes.  The CCM epilogue is
not affected.

If a job was submitted with a deadline and no time_limit or min_time,
but the system has a QOS MaxWall the job's time_limit would be set
to the QOS limit. Since there is no min_time specified, the QOS MaxWall
would be treated as a min and max time limit for the job and potentially
make the deadline impossible to satisfy. Now we set the min_time to
1 minute of there is a deadline, but no time_limit or min_time.

Also make sure the job is cancelled at the end of the test

Add TopologyParam option of "TopoOptional" to optimize network topology
    only for jobs requesting it.

Timeout stalled transfers and cleanup related data structures. Default
to wait five minutes since last update. Hook onto registration/ping message
type to trigger cleanup in a minimally invasive manner.

While here restructure certain functions to use list_* functions
rather than iterate on the structures.

Otherwise --mail-type=ALL will send an unexpected stage_out message back
to the user.

Siphash is a state of the art keyed hash function that is performance competitive with the usual non-cryptographic hash functions. It's used as the default hash function backing hash tables in e.g. Perl, Python, Rust, and so on. Here we initially use it for the gid cache hash table, and in the common xhash implementation.

step_ptr->job_ptr is already dereferenced several times by now, so
null check is unnecessary here.

If a job fails stage in, set its reason to BurstBufferOperation
with a string describing what happened. Previously the reason was
set to AdminHeld on stage-in failure.

Make default compression vary based on library availability.

This change preserves the old value, which can fix a possible
