Updated exit(0) to exit(EXIT_SUCCESS) in req_rerunjob for continuity.
Made it so trquathd can be pinged. This was done so we
can make sure that only one trqauthd is running at a time.
TRQ-2118
TRQ-2350 - fix issue with parse_cpu_string() that would cause it to go into an
infinite loop and hang pbs_mom on startup when --enable-numa-support set
Fixed a problem in issue_to_svr on a retry condition where
the batch reqeust gets freed before the associated task can
be freed.

Also modified reissue_to_svr to fix a segault where the batch_request
was null but we dereferenced it before checking.

to simplify code.
