Added the slurm_job_cpus_used_on_node_inx() slurm_job_cpus_used_on_node() API for working with the job_resources_t structure.

   slurm.h and deleted job_info.h.

--enable-debug no longer has to be stated at configure time to have the slurmctld or slurmstepd dump core on a seg fault.

    any other processing in spank_init().  This now prevents fatal errors from
    being mistakenly treated as recoverable.

When querying database for jobs in certain state and a time period is given only jobs in that state during the period will be returned, previously if a time period was given in sacct jobs eligible to run or running would be displayed, which is still the default if no states are requested.

    name of NULL rather than returning no information about the node so that
    node index information is still valid.

    --sockets-per-node, --cores-per-socket and --threads-per-core options.
    Remove --mincores, --minsockets, --minthreads options (map them to 
    minimum values of -sockets-per-node, --cores-per-socket and 
    --threads-per-core for now).

    preemptable and preempted jobs (both new and old format of commands are
    supported).

SLURM_IMMEDIATE_EXIT to SLURM_EXIT_IMMEDIATE

    to permit user control over exit codes so application exit codes can be
    distiguished from those generated by SLURM. SLURM_ERROR_EXIT specifies the
    exit code when a SLURM error occurs. SLURM_IMMEDIATE_EXIT specifies the 
    exit code when the --immediate option is specified and resources are not
    available. Any other non-zero exit code would be that of the application
    run by SLURM.

    gang scheduling module. Make identification of preemptable jobs an argument
    to the select_g_job_test function rather than calling preempt plugin from
    the select plugin. Make output of srun --test-only option include a list
    of preempted job IDs.
