advent of persistent connections.

Try to fill up each socket completely before moving into additional
sockets. This will minimize the number of sockets needed, improving
packing especially alongside MaxCPUsPerNode.

the pipe as if it was an int.

Coverity issue 182984

Requeued jobs are marked as PENDING|COMPLETING until the epilog checks
in. The issue is that if job_set_alloc_tres gets called while in the
PENDING|COMPLETING state, the job's alloc_tres_str will be free'd. If
this job then gets checkpointed in this state (PENDING|COMPLETING + no
tres_alloc_str) on startup the controller would crash because it
expected the job to have a tres_alloc_str/cnt when in the COMPLETING
state. This could be triggered if starting the controller without the
dbd up. When the dbd comes up, the assoc_cache_mgr calls
_update_job_tres() which calls job_set_alloc_tres. It could also be
triggered by adding new tres.

This most likely started happening in 17.11.5 because of commit
865b672f which introduced calling _update_job_tres() on each job
after the dbd comes up.
