Made it so it complies with SWF standard and that it reads from command
line the output for the file

Add swf2trace with Wilmer's changes that made it readble by sim_mgr

Porting to 17.11 finished; proper freeing of helper msgs, msg pack and unpack functions fixed, some function names were changed i, version 17, signal-based slurmd registration converted to shared memory var based registration

bf_queue_limit parameter added to limit jobs checked in the queue to be backfilled. It is a slurm.conf parameter

Fixed a case of synch in which slurmd was not waiting next second to pass before entering next cycle

Created new fields in job structure, then exported by jobcomp plugin to generate more information about scheduling

MAX_RANGE for maximum number of nodes increased, backfill and normal scheduler statistics, in swf2trace number of tasks equals number of requested CPUs
