modes to make use of new parser, also fix for overlap block creation along with full system block creation.

Update information on files and directories.

auto-initialization.

Add test for down XCPU nodes.
Add chmod to XCPU nodes on job start/termination.

New general configuration file parser and slurm.conf handling code.
Allows long lines to be continued on the next line by ending with a "\".
Whitespace is allowed between the key and "=", and between the "=" and
value.

slurm.conf is now read only once, and resulting data structures can be
shared between application and slurm library code.

WARNING: A NodeName may now occur only once in a slurm.conf file.
  If you want to temporarily make nodes DOWN in the slurm.conf,
  use the new DownNodes keyword (see "man slurm.conf").

the "squeue" used for testing was not first in the search
path or totalviewcli passed a full pathname of a node
(e.g. "linux123.llnl.gov" instead of "linux123"). Finally
totalview 7.1.1 is required on infiniband systems to run
(manually alter totalviewcli pathame in the globals file 
as needed).

Tweak test7.4 to work with current totalviewcli script.
