 o added new function unsetenvp() to support above

the old_job_allocation response so as to conform with job step's specification.
For example, remove nodes that are excluded (-x), set the node count to
that requested (-N, eliminate nodes as required), etc. This requires
modifying the node list including the slurm_addr, and cpu_count arrays.

Add new logic to prevent some node state transitions via update_node RPC
(e.g. IDLE to ALLOCATED).

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

allocated may differ from the value displayed.

If a node registers and fails to show a batch job that should have a

Changed the logging level of a few other message.
