By default, logging is to syslog. Expanded usage description to be more
complete.

without duplicates. For example, we want to convert a users request for
nodes "lx1,lx2,lx1,lx3" to "lx[1-3]".

entry counting function. As a job is completing the bitmap gets cleared
as nodes complete, resulting in incorrect values.

required by a pending job. NOTE: On heterogeneous systems or if the
requested number of nodes is a range then the actual number of nodes
allocated may differ from the value displayed.

batch_job_launch RPC, then deallocate those resources and requeue the job.
If a node registers and fails to show a batch job that should have a
script running there (node zero of allocation), then consider the job
complete.

"Can't connect to node" with every ping failure.

Changed the logging level of a few other message.

until the previous one completes. This avoids having too many cycles
active (and a bunch of threads too). Ping_nodes control functions moved
to a new module.

changed from 10msec to 1usec by changing to gettimeofday instead of clock.

Set "reason" field when node set down for slurmd error.

the backup controller and proc_req.c is the code to process incomming
RPCs. No changes in controller logic were made for this.
job_mgr.c was also modified to better handle bad job records on
controller restart's data recovery.

  - Enhanced xsignal.[ch] to more easily block and unblock sets of signals
    [ added: xsignal_unblock xsignal_sigset_create, changed: xsignal_unblock ]
  - Take advantage of above changes in srun and slurmd code
  - Only unblock signals that were specifically blocked in slurmd
    (instead of *all* signals) when exec'ing user tasks.

 o allow error() to return SLURM_ERROR so callers can do:
     return error (...);

of DRAINED from DOWN state.
