Added ability to query batch step with sstat.  Currently no accounting data is stored for the batch step, but the internals are inplace if we decide to do that in the future.

Fixed regression in pre12 in crypto/munge when running with --enable-multiple-slurmd which would cause the slurmd's to core.

    libraries are not generally usable.

    safe version of the MySQL library is used.

    - Persistent option selections for each tab page
    - Clean up topology in grids
    - Leverage AllowGroups and Hidden options
    - Cascade full-info popups for ease of selection

   the exit code of the job script (or salloc) while derived_ec contains the
   highest exit code of all the job steps.
-- Added SLURM_JOB_EXIT_CODE and SLURM_JOB_DERIVED_EC variables to the
   EpilogSlurmctld environment

    job specifies it's memory requirement, then more CPUs than requested will
    automatically be allocated to a job to honor the MaxMemPerCPU parameter.

    to partitions configured with AllowGroups.

    to abort.

    slurm_job_step_stat() from user commands.

    for job termination when slurmctld restarts or reconfigures.

    future that the backfill scheduler will look when considering jobs to start.
    The default value is one day. See "man slurm.conf" for details.

    bitmap input before setting the bits indicated in the input string.

    srun. Patch from Hongia Cao, NUDT.

Export more symbols in libslurm for job and node state information     translation (numbers to strings). Patch from Hongia Cao, NUDT.

   cache from becoming corrupted when a hostname cannot be resolved.

    on each node after releasing some nodes from the job's allocation.

    Avoid killing the job step on remaining nodes. Patch from Rod Schultz
    (BULL).

    Previously, some commands support one of those options, but not the other.

    hostlist_ranged_string_xmalloc, hostlist_deranged_string_malloc, and
    hostlist_deranged_string_xmalloc which will allocate memory as needed.

    fixed size buffers (typically 8192 bytes). This patch fixes many, but not
    all possible problems.
