anyway to attempt to log the backtraces of the potential
unkillable processes.

667f1105.

We have decided to go back to the way 15.08 called NHC instead of calling
it first before sending a SIGKILL to the steps tasks.  With this patch we
only start the NHC early when we have to resend the SIGKILL for unkillable
processes.  This will hopefully get us the backtrace of the unkillable
processes which was the reason we did it this way in the first place :).

We will most likely redo this logic (as it appears to be duplicated) in
a following patch.

Don't generate an error when a batch job is submitted that must wait
  for stage-in before starting.

This might be the cause of run away jobs.  I couldn't see how an end_time
could be 0, but if it was it would just exit and never set time_end to
anything.  At least if it happens now we can have an idea that it is
possible and we will have an idea this is the place it happens.

This will keep from referencing the task array that might not be set up
correctly in src/common/plugstack.c _spank_handle_init().

Prevent possible incorrect counting of GRES of a given type if a node has
    the multiple "types" of a given GRES "name", which could over-subscribe
    GRES of a given type.

The wrong variable was being used in gres.c to print a message of
this sort:
error: gres/gpu: job 7135 dealloc node ### type ### gres count underflow (# #)
The first number in the parenthesis was based upon the wrong index and it's
contents garbage
