o set exit code to 1 if any tasks failed

   to srun or slurmctld.
 o new errno ESLURMD_UID_NOT_FOUND

functions, but only for a single task. Multi-task support will need to
wait for modifications to srun and its communications protocol.

sharing via node record of job count (0 | 1) and bitmap of nodes which
permit sharing. Previous logic could permit a job accepting shared nodes
to be scheduled on a node that already had a running job not accepting
shared nodes.

Just log open failure and continue.

failure as fatal error.

failure, log with fatal() and exit.

exit rather than log with error() and continue (which causes abnormal behavior).

job logs, state save directories, etc.

configuring the user authentication mechanism.

its support.

Update configuration parameter information for slurm version 0.3.

 o more fixes for setenvpf() corner cases
 o move tmpdir logic up so it is not executed unecessarily for every task.
 o add getenvp() call to setenvpf.c

    always appended.

configuration file has changed (important for long-running jobs,
especially DPCS daemons).

This logic was added temporarily for testing gnats slurm/223.

Avoid sending TASKS=0 to Wiki; Maui silently rejects the job (insofar as Maui silently does anything)

sets new environment variable SLURM_CPUS_ON_NODE for use by LAM/MPI.
Also fixed bug in srun task distribution logic for block distribution
in heterogeneous cluster.

gracefully kill all jobs allocated resources on those nodes,
gracefully kill all pending jobs that require those nodes,
leave pending jobs that exclude those nodes but ignore those nodes.
Added "best_effort" argument to node_name2bitmap() function.
Fix potential memory leak when maui scheduler interface resets
the required nodes.
